Nowadays I get much more pleasure taking small systems to venue's and watching reactions when the "toys" perform perfectly adequately for the job. I have built this little jobby just to test the alignment that I will use in a twin version. I have been a bit aggressive with the tuning and have gone for a couple of db lift at the bottom end instead of the flat response that I normally go for. It is still -3db at 42 hz and -6 at 38 hz not bad for a 12" in a 40l box. efficiency is on the low side though and I should get a max'm output of about 119db continuous. I am hoping output for the twin model will be close to the theoretical 125db which should be ample for most pubs/small clubs.

Looking good there Tony. I have still yet to house my 12" subs I bought from you. lol. I started to build a double cab. Made it 110 litres and got 124db max spl from sims. Saw this tapped horn stuff, put the info in there and now Im getting 125db at 39hz just from the one driver at 99 litres I think it was. Has a bit of a dip between 40 and 100 hz but some eq could help that out i hope. Have the stuff ready on HR but have no idea how to put this data in to a cab. I downloaded google skecth but have no idea where to start. Anyway, just out of interest, why is the port on the back instead of the front? To keep the cab more compact in size??? |

| That looks really good, how did u model the port being close to the driver? did you just add an estimated length to the port?? |
Posted By: Tony Wilkes
Date Posted: 08 July 2009 at 8:07pm
No I use bassbox pro to get an approx length then build and measure the exact frequency. On this design I bring the port to within 40mm of the magnet assembly. This added air resistance actually drops the port frequency by a couple of hz. On this box the port frequency is 45hz. Tony |

Port is on the back mainly to allow me to check Magnet temps, also has the benefits of smaller baffle, less port noise and it has to help cooling. Tony |

Lovely build there Tony. How much gas do you have to give it to get the 119dB?

Its a 600w driver. I have tested it on one of Andy's xp5000's so getting about 1200w with the clip light flickering and the little bugger still seems quite happy, high-passed at 38hz. No problems with Xmax due to the choice of port frequency & dia. etc. Due to have some much more meatier tests soon when I check temp. rise. I mentioned dub to it and it went and hid in the corner  Tony |

| Looks very nice, Tony, as usual. What are your thoughts on the rubber surround? I'd be worried that it's too floppy. Also, what's the UK price on those - I can't find it anywhere. My main problem with cabs that size is port noise. I'm very interested to see how you get on. |
Posted By: Tony Wilkes
Date Posted: 09 July 2009 at 7:06pm
Stevie The rubber surround is unlike what you are probably thinking and is actually quite stiff. When I first saw one of these drivers I tried pushing the cone , as you do, and was amazed at how much resistance there was. Not at all like your typical Hi-Fi driver rubber roll surround. There is no problem at all with port noise, when used with a mid-top my ears are ringing well before I can hear any chuffing. Tony |

Jake, I built it really just to check the tuning alignment I had chosen. They will be used for the basis of some twin boxes which will be used for live bands for up to 150 pepes and also some disco use (cheesy wedding type). I also have to build a pair for a local install as the customer wants a small profile system which will still sound good and have a fair kick to them. Used with my twin 8" mid-tops crossed at 180hz they really do sound very civilised indeed. The only downside is the lack of efficiency and they need a high output amp to get the best out of them. They are quite happy on one of the new Matrix XP5000,s with the clip light just flashing so really you are looking at twice the continuous rating at 600w so 1200w / driver. Tony |

bit of topic but what paint did u use on them is it aldcroft |
Posted By: Tony Wilkes
Date Posted: 26 July 2009 at 8:36am
Yep Aldcroft. First 2 coats thinned with 25% Water and then 5-6 coats applied thickly with a 4" foam roller. The key is to apply thickly which helps eliminate the roller marks and also achieves the textured finish. Best done as well on a cool dampish day. It is slower drying but helps with the finish. Then allow a week for the paint to fully harden. Tony |

I traveled up from Kent to meet up with Tony on Saturday afternoon (going to a party in Chesterfield that evening) to have a listen to this speaker (and a few others) in the cabs. I was simply gob smacked by the output of bass and sub bass this 12" driver was putting out. Played a few tracks that I would use for mobile dj use and it played very well. Hit the sub with some dubstep and boy did it sound nice.  . The single 12" sounded deeper than the two single 15" Tony was using. After to talking to Tony more about this, the single 12" goes around 5hz deeper than the single 15" h was using I believe? Just thought I would share this.

Hi Tom, Glad you enjoyed the experience. Hope the rest of your day went well. It was the first time that I had heard that box on the end of an XP5000 in a largish room giving out some serious levels and it was nice to confirm the simms. that it does indeed go deeper than the 15" ers. The twin driver models I am set to build should actually give me the same output as the single 15", with the extension of an 18" but loosing none of the so called "fast bass". For house party's etc. just stick a single 12" in a corner and stand back Tony |

I've been successfully using a cab almost identical to Tony's. I know that many here aren't happy unless their internal organs are being damaged by the bass, but for most low volume situations I am using just a single cabinet. I have also tried the drive unit in a 6th order bandpass which worked well too. The original ports (some plastic tubing I had lying around) were too small and I damaged the box trying to modify it, hence the bass reflex. I've got a measured response plot around somewhere and I'll upload it if I get the chance. As Tony said it needs very little eq to get a flat response. I originally built the cabinet to compliment a couple of bms 8" coax units but have since used them with my other mid-top cabinets. At the levels I am running at power has never been an issue but for those interested I've either used one side of a RMX1450 or Yamaha P7000.  a bit blurred but the amp gives an idea of the size.  The bandpass was slightly smaller than the reflex. |

Smiles all round when they had done the sound check, we had only 100 in the audience but the quality of vocals on those little twin 8" ers was simply amazing and even with DI'ed keys etc the system still had about 6db headroom available.

Steve, It was your comments to me about your smaller box that prompted me to try a different alignment for this driver. Originally I was going to stick them in some 60L boxes and go for bottom end but decided to forgo 10hz and get a bit more output. Really pleased with the result, thank you for the prompt.  Tony |

Been lurking here for a while - just wanted to post a massive thanks and respect: A lot of people, including myself, end up with the idea that for good fun you need insanely large boxes - but you cant get these in your car, cant take them round a mates house on a whim on a saturday evening, cant turn up in the middle of the estate with them, cant offer their use or happily lend them out, etc. With the police cutting so hard especially around london on proper parties, smaller gigs are the way to go, so smaller kit that properly cuts it is very cool. Getting a fit for the purpose sound from a tiny system has to be the holy grail. This sub of yours is a spectacularly saleable piece, and you have done an amazing build and finish ( i know its an easy cab but i still see the details :-) ). are you going to produce and sell these i wonder? an active version might be interesting...... Im looking at mini-tapped-horns / advanced reflex loading at the moment, but perhaps its not worth it and I should try to copy what you have done here... what do you think? |
Posted By: Tony Wilkes
Date Posted: 20 August 2009 at 5:45pm
mrchay, thank you for those kind words they really are appreciated.  I do make a few of these boxes for sale and in fact I am just about to start a pair of the twin 12" units for a local install. An active version with a 1000w digital amp. (B&O) would certainly be interesting. it could do some real damage as a home theatre sub. Tony p.s You are welcome to a copy of the drawing as a PDF but they really are optimised for a specific driver as noted. Just pm me your proper Email address. |

Here is a plot of the frequency response of the bms12 in a reflex cabinet. Measurement was done outside with both the speaker and microphone placed on the floor. edit: forgot to mention this is pre eq.

Steve, Very similar curve to that I have measured. The hump on my box is very slightly lower and centred on 60hz which is caused by the slightly bigger box of coarse. Only a tiny bit of EQ needed to get it flat to 40hz . What program do you use to display the FR graphs etc? Tony |
Posted By: Steve_B
Date Posted: 22 August 2009 at 4:50am

Tony, It is an older version of Smaart. I got it in exchange for some work I did for an acquaintance who has moved on from his audio obsession and no longer needed it. Prior to that I used to borrow Spectralab from work. As I now consider audio to be more of a hobby than job I couldn't really justify a big spend on software for the amount of speakers I now build. I was just fortunate to know the right person at the right time. If you are measuring outside or in an anechoic environment using a pink noise source, then you know that the reference source is flat and a RTA read out gives the same response as a transfer function. The phase measurement makes setting up crossover points easier and the coherence plot highlights where the curve is giving a false reading, but by changing the test setup and getting similar readings you can be confident that your measurements are good. Anything with a higher res than 1/12 octave should get close. In most cases if you set up the same cabinet three times you end up with three slightly different settings on the crossover eq. If the measurements are wildly different something is wrong. One of the problems with aligning subs with mid/tops on a tripod stand is not being able to set up consistently at gigs. I usually do a few measurements putting the cabs in different positions to try an get a feel for what is happening. At pub gigs there is never a chance to do any alignment in situ. |

| It's difficult to tell from this distance, but tuning the box lower might flatten the peak at 60Hz and produce some more useful output below this. |
Posted By: Tony Wilkes
Date Posted: 28 August 2009 at 5:24pm
|
Both myself and Steve_B deliberately wanted the peak which gives about 2db at just about the most influential bass frequency. It is a trade off between extension and size but one which seems to work very well indeed. If you just want extension then just build a 60L box tuned to 28hz and they will go lower than most 18" ers i.e. -3db @ 32hz. Tony |

In my opinion people get too obsessive about getting the flattest most extended response they can from a cabinet design. Don't forget that the loudspeaker is acting as a high-pass filter. If you add an electronic filter in series the response is combined. With modern electronics eqing a flat response is easy. The effects can be simulated in winisd. Sticking with the bms 12" driver this first image simulates three boxes. One is close enough to the box that I built (blue trace). The second is the same box with a -1.0dB cut at 55Hz (red trace) and the third shows a 74 litre box tuned to 32Hz. From these simulations the options seem to be a small box or an extended response. For me all things equal extending the response down to 32Hz from 38Hz wouldn't be worth it anyway for the bigger sized box.  This second graph shows the same three boxes but now plots the maximum spl based on power and xmax. Although the yellow trace (big box) has an increased output below 38Hz the maximum output above 38Hz is less than the small box. Note that the maximum output of the two smaller boxes is identical (you can only see one trace) with the -1.0dB filter at 55Hz the power is reduced at the same point that the output is limited by xmax. For most PA and disco applications where the loudspeaker is operating close to capacity the smaller box will give a better bass output than the large cabinet.  |

| If you stick with the 48 litre box but tune at 42Hz instead of 47Hz, you will lose the peak at 60Hz and gain another 2dBs at 40Hz - that's what I meant. I've got it plotted in BassBox but I don't know how to upload images to the forum. If you want the peak at 60Hz, fair enough. |

Prediction programs are not that accurate. One parameter that I have never seen discussed here is Ql or box loss. This can only be measured after you have built the cabinet so any prediction software has to use an estimated value. Each software designer might use a different value. The graph of my original cabinet was tuned to 38Hz not 47Hz. Using the values you have given winisd predicts an even bigger peak this is what I would expect. A 47Hz tuning would give an even bigger peak. The original image I posted was a measured response. It conforms closely with the predicted response in winisd which gives me confidence in the programs accuracy. To show images you need to upload them to a website and then provide a link. If you don't have your own webspace there are loads of sites that host images for free. For posting on speakerplans I use tinypic.com. It will automatically resize your image to fit different formats and provides the tagged link which you just copy and paste into your message. |

I can help with the drivers but would prefer if you get a quote for the boxes from one of the box builders on this site. I personally have used Dom on here who has always delivered but I know that there are load of competent builders on here. They will seem expensive if you compare them to the budget stuff by Mackie, Peavey, Yamaha etc. but are considerably less than the proper high-end stuff that they should be compared with. Tony |

Kevin Yes I have been using them a while now. Similar output to a typical single 18" but in 70L. These are tuned like the single 12" @ 45hz and have a simmed -3db of 43hz. To use a hi-fi term they really have a slam to them. Have also done slightly bigger boxes of 45L per driver tuned to 38hz. The simple system below has got more praise than anything that I have ever taken out.  |

SamV, I suppose 20 years as an industrial designer must help + I like to keep things nice and simple as long as it does not inhibit performance. The main tool I use for quick plots is Real_RTA I find it just as accurate as the more expensive programmes that I have access too. I use it with a berry ECM8000 as I mainly do comparison checks for which this is perfectly OK. An Earthworks mike is probably on the cards in the next few months.

Yes it does, you can save the plots to a series of memory positions for comparisons. If you download the demo version you can see how it works but only in 1 octave resolution. It will work with your laptop mic if you have one (not for proper use). If you register with these guys you can also download the latest version of Room EQ Wizard 5 for free which also does what you want. http://www.hometheatershack.com/forums/rew-forum/ - http://www.hometheatershack.com/forums/rew-forum/ Tony ------------- www.forteaudio.eu - BMS - db-Mark Processors - Lexon (SAE) |

hi Tony
i found the mackie thumpy but not really articulate, i havent had time yet to get in anywhere and really tweak the beyma boxes at a high level, but they seem to blend with the beyma 12" mid tops quite well, so only time will tell, being able to carry one in each hand and lose the speaker stands was a huge consideration to be honest, but i am more than happy with the sound so far, and the option of being able to hide the boxes under tables and other obstacles where you wouldnt be able to with a bigger box is marvelous too,
i need to get some grilles on them, i rolled up at a swanky bar last night, and you know that look when you walk in with all your gear?, well they were too busy clocking me, they didnt notice the huge cochroach that ran out the front of my sub when i placed it on the stage
 not sure what the score is with that poly glue, the overall appearance of the finished job does not reflect the care i took with the build, it just seemed to froth up and end up all over the place.
hope you are well mate
cheers

Kev, I have found that not all PU glues are born equal. I have been using some for a couple of years that is absolutely brilliant. It does foam as you say but the excess just simply trims away with a chisel to leave a really clean joint. However with some that I have had from Screwfix and other places the extruded excess seems to remain tacky long after the joint has actually bonded and you either have to wait 24 hrs for it to completely dry and it is then a bitch to get off or you tackle it early and it gets everywhere. The one thing that I have found with all of the PU glues is the ease with which it does sand off ready for painting etc. Yes mate I am very well at the moment with plenty to do and keep me out of trouble. How is your life in the Sun? A mate of mine that does the same type of thing as you reckons work has picked up the last 12 months after a tricky period following the big crash.

hi tony
i'm going to presume i had the el screwfix glue then
 it was stuck to the hairs on my arms and everywhere, i tried to clean it with thinners but had to scrape it off in the end.its not too bad here, the problem with the work is the bars and fooderies are trying to introduce a one price fits all policy, which stinks when you compare belting out tom jones and joe cocker at full belt with someone who transposes ub40 in to an even easier key that it was written in??
but its a nice life here so i mustnt complain
glad you are busy and well, will let you know how i get on with my projects.

Tony, the 2x12 and 2x8+HF? system looks perfect for a small 3k PA and rehearsal room set up. Can I get the designs for both please ?? Cheers, Rob.  Actually the single 12 design would be better for the rehearsal room, so all 3 designs please

I presume you mean the 12SB30, no it is nothing like the BMS, the performance of this little cab is tied in directly with the recommended drivers. Anyone wanting plans just PM your Email address. Tony ------------- www.forteaudio.eu - BMS - db-Mark Processors - Lexon (SAE) |

That looks like a really nice, portable system. What size rooms/numbers can this handle at decent levels? What type of amplification does it need? Does anyone build these to order and if so, how much would a pair of each cost? |

I have used the F208/ F212B combo above for a few months now( in fact that actual pair in the photo ) and they are awesome for small to medium DJ use for parties and weddings. I would say up to 200 people at a wedding or party, but reducing to 150 for heavy stuff like dubstep. I use one of Tony's dB Mark 24 mk 2 processors as well as a Minidrive, and one of Andy's XT 6004EQ 4 channel amps. It handles the power with ease and just seems to get louder and louder without distortion as far up as I need to go. Never had to go above half power yet, as it just too bloody loud. Sound quality is fabulous, with female vocal being superb, and bass is just mind-blowing for such a small system. There is a photo of my Xmas set-up on Tony's new website at forte.audio.eu in the blog column I believe. ------------- Protect your hearing, and feel the music. MU South East Roving Safety Rep. |

Safety man im in surrey and my mate lives in Brighton iv built those bass cabs too, fancy a link up and see what damage 2 pairs could do together!! And yes they just are great speakers!! Fact ------------- I do a sideline in ply wood wheels. |

Hi Tony, Yes, still love the speakers and, more to the point, the punters really do too. Not heard anyone dislike the sound yet !! Hi Edd Jordan, Yes, a link-up will be fine, thanks for offering. 4 subs together, and 2 pairs of satellites would be an interesting combo ! Are your bins neodym, and the tops ferrite drivers ? Mine are. ------------- Protect your hearing, and feel the music. MU South East Roving Safety Rep. |

Oh, ok for the dual 6's tops. I play all kinds of music for parties, though not usually dubstep . Yes a link up will be ok, thanks ------------- Protect your hearing, and feel the music. MU South East Roving Safety Rep. |

Joined to find a compact ported design to build for a bass guitar- this looks like what I envisaged, 1 x 15 or 2 x 15 I was thinking. Any advice would be very gratefully received. Thanks Mike

Hi Mike, I have not used it 'live' yet, nor with a bass guitar. However the 2x12's produce a phenomenal amount of bass on recorded music up to 200hz. The combo with 2x8 tops that I use give an excellent overall sound. However, for bass guitar you may need something a bit different. Tony Wikes will be able to guide you far better than I, as he is the designer/builder of these cabs. ------------- Protect your hearing, and feel the music. MU South East Roving Safety Rep. |

| tony, in your research for drivers that work in a small sub application, what others did you test? your current choice is quite hard to find in the usa but the box and its intended use is right up the alley i need. other drivers that might work in a small sub? |

Speak to Jack Arnott of Assistance Audio http://www.assistanceaudio.com/ He will sort you out. Tell him Tony in the UK sent you :) In this box the driver IS everything, IMHO the 12S330/12N630 cannot be beaten at least for a reasonable price. It is not till you get your hands on a 12S330 that you realise what a piece of engineering it is. Tony ------------- www.forteaudio.eu - BMS - db-Mark Processors - Lexon (SAE) |

Hello, it's my first post here... I was just designing a subwoofer using a pair of BMS 12N630, and I found this thread! My idea was to run them in 90 liters and tune using a 250 cm2 port, 45cm long. This will give a moderate peak in the 50 Hz area, with about -1 dB @ 40 Hz and 30 Hz @ about -8 dB. You can see details in the attached image. I will build a pair of these subs (so total 4 woofers) to be used when djing, usually in not very large rooms. Is it possible to get the plans for the design you're discussing about, so I'll be checking and compare this to my design? My mail address is roberto at ddaudio.it Many thanks in advance, and congrats for your good job! Roberto http://shack.us/photo/my-s/713/2bms12n630.png/ -  |

Adding to that, as the OP is offering the Q12 as flat pack, why would you even need plans? Oh... right...

Tony I requested the drawing for the 1 x 12 design almost 3 years ago, but never got round to building it (hangs head in shame) Has the design changed at all? The drawing I received was F112BN and had an Fb of 45hz Just thought i'd ask before attempting to (finally) have a go. Are the designs for the tops available too???? Thank you.

Hiya Jon, I have only changed items like the handle position etc. the basic box at 35L tuned to 45hz is exactly the same. I have just done a dedicated top box for use with single Q12's which is the Q25. As the name suggests it uses twin 5" drivers with the top one being a co-axial jobby. Not released details yet as the boxes are being cut and as usual will not release details until they have proven that they perform. If you are going to be using 2 x Q12 per side then you need a bit more oomph and the Q28 (2 x 8") was designed for this. The plans are available for the Q12 and Q28 and also the STP and IGES files for anyone with 3d capable CAD. There are no dimensions on the new drawings you would need Draftsight or similar to get dimensions from the DXF. http://www.3ds.com/products-services/draftsight/overview/" rel="nofollow - http://www.3ds.com/products-services/draftsight/overview/ Tony ------------- www.forteaudio.eu - BMS - db-Mark Processors - Lexon (SAE) |
