In the search for a compact sub i came across the 18sw115 driver from b&c. On the website of b&c they have a "suggested design" for the 18sw115, but with the ports on the plan there would be a vent speed of 72 m/s (if given 1700 Watt each). After some research i learned that 30 m/s is the max acceptable vent speed? Thinking about the ventnoise I started simulating with winisd alpha. B&C recommend a 150 L enclosure tuned to 35 Hz, The ports in the simulation are 90x450mm with a vent length of 500mm, this time there was a vent speed of 28 m/s. I would like the vent at the side of the cabinet, so the vent would be shelved. After reading some topics on different website's I learned that shelved ports have some influence on the tuning. Knowing this, i simulated the b&c sub18 design, and tried t0 achieve the same tuning (with 18tbx100). By doing this I calculated that the shelved ports need to be factor 0,6 shorter then simulated. Would this be a good guess? Why I chose this driver? I needed a compact sub, that is capable of reaching 30/35 Hz. Also soundquality wise I prefer reflex designs. |

 Here are some results from winISD. The rear chamber of the BP is tuned to 35 Hz with a volume of 150 L, the front chamber is tuned to 80 Hz with a volume of 40 L. both have a SPL of 92 dB @35 Hz. (Both don't have a flat response). 36 Hz and up the BP wins in the simulation.

It will definitely not gonna be a horn or scoop. They are just to big for my applications. I've read that some BP cabinets are described as slow, but for an example the nexo ls600 or ls18 isn't slow. Could the port lenght have influence on that?

Hey there. Quite late. I have 18SW115 in about 130-135l box tuned at 34Hz for home audio. Works good from 35Hz, does some sound down to 29Hz. I believe the length of the reflex doesn´t have to be that short. Propably 0,8. Depends... Best way is to make a prototype box, and if you cannot, best way is to make shorter reflex, and then add pieces to make it longer. Once you secure it well (screws) and seal holes and spaces between those pieces (silicone) it´will lead to your preferred tuning, and nobody will see the inner work anyway. ------------- Nikon and Canon people should not be married to each other.

Two B&C 18SW115-8 drivers are ordered for some testing. Within a couple of weeks I want to measure two different cabs with REW. A reccomended cab from B&C is already made from mdf (for testing). If the port noise is to loud (what I expect) there will be build another cab with a bigger (and flared) port. Also the TH-18 from Xoc1 seems interesting.. PS: Testing will be done with a NEXT MQ10000 (bridged) and a EV DC-ONE.

Wow, awesome! I always used B&C speakers, and didnt like its high excursion performance (some unwanted noise coming out of the speaker 12PS100,12TBX100,15PS76,15PS100,15TBX100,18PS76,18PZB100,18TBX100). When mounted in the box, it wasnt audible (mostly), but I was not really happy. Now with 18SW115, its different league. Driven to Xmax of about +-15mm, the cone movement is very "cultivated" with very little (expectable amount) of noise. I was surprised positively with this. They finally DID IT! Good times coming. :-) 150l@35Hz should work, but yeah, the bassreflex area is "thin line walking" with 340mm2. Will loose efficiency when driven with large signal. I got 512 on mine, and that´s where I would say no less for noise free audio. With 21", Ill have to approach 650-700cm2 mark. ------------- Nikon and Canon people should not be married to each other.

I would recommend the Keystone TH design for that driver if you go that route. There are comparisons to a reflex loaded with the same driver too |

I've read about the keystone sub, but the dimensions are not ideal for my applications. The Th-18 with its dimensions would be better suited for me. Eventually like al builds there have to be made compromises between SPL,low frequency extension and size. I hope the BR will perform up to my expectations, if that is not the case I will look further (maybe even BP).

Thats a shame :-D Hope you like them after you test them. I found these to be superb compared to previous B&C versions. The bad side is that now they spoiled me with 21DS115. The speaker looks like "business." Or rather GORE. ;-D Two 18SW115 are stronger still, so be careful of yourself at home.

That´s weird. It should do a lot. Of course, not very sensitive driver, but goes deep easily. Also modern high-Bl drivers with higher impedance need higher voltages and equalization to drive these at rated powers. Conventional usage is not a way to go for best outcome with these. ------------- Nikon and Canon people should not be married to each other. Why did you let this happen? |

B&C SUB 18 needs heavy bracing inside to stop panels from resonating! This is really important especialy with this monster driver! |

ive A&B the 2 differant cabs ,the b&c sub & this mini scoop,..ok the sub was a lot smaller but also a 3rd of the output of the scoop,. to me that speaker was a waste in that b&c sub,.probably good for the smaller b&c's but not the sw,.try & get your hands on a mini scoop,i suppose the tapped horn would work aswell but as marko said,, what ever cab you go for you need some real solid bracing,.    |

And whatever your findings may be, if you want to test them in some huge(1x1x0.6m) tapped horns to see what they can do, i am still curious how these drivers would perform in my Tapped horns. Where are you from? ------------- Best regards, Teun. |

Those mini scoops look rather big still, how many liters is that one, 400? I've built a pair of keystones with these drivers that I use atm, monster output very clean sounding, solid nice kick 100-110 hz. Could bark a bit more tho to my taste for techno but I guess it's due to the low distortion.. sounds different compared to my flh's which has a nice compression bark up close and more 'snappy' sound but not even close in output at a little less than double the liters(I have four t30 3012lf loaded, eight would probably be somewhat equivalent with two keystones) |

Th-18 it is! The output was very nice, and deep enough. They will have a full grill, and two m20 plates for a top cabinet (what will be the next project). The panels for the cabinet will be done by a professional company. Paint and overal finish will be done by myself.

A small update  The processing for the complete system will be done by a Xilica XP3060. For amplification I am thinking of a fp14000 (copy)  and a fp10000q for the top cabinets.And I bought a pair B&C DE800 drivers with two 18sound XR1496 horns. I also have a pair B&C 12NW76 drivers laying around, but they don't sim great in a reflex enclosure. The top cabinet wil be the next project A pic of the DE800 (with horn) and a 12NW76.  And a pic of the S18CN.  I have two more foto's, but since the build I have a new phone  |

Nice! 12NW76 speakers are very sensitive and loud, but sure, don´t go low. I would not hesitate to equalize these heavily though. It can take some excursion. I finally made my decision and bought 21DS115. Behaves very well, I´d say the same as 18SW115, except for that it goes few Hz lower.

Yup, the nw76 isnt a great reflex driver. Mine are in sealed monitors. They dont drop very low, but produce a very nice tight punchy sound very well suited as vocal stage monitors. Definitely always require a sub when used as tops in a pa system. ------------- Best regards, Teun. |

Yeah, that value of Qts says although they will work in a reflex box and it'll be fairly small, you'll never get any significant low end out of them. But I bet they are good for vocals and fast transients, very strong motor in that relatively small driver with strong damping. I bet they'd make a good horn driver too with the right design. |
Posted By: smitske96
Date Posted: 04 February 2017 at 10:32pm

The top cabs will only be used 100 Hz and up. So maybe the 12NW76 wil work. The aim is a small 12/1.4 reflex cab. The nw76 sims good enough tuned at 80 Hz but de cab would be +-26 L, that's pretty small, and the xr1496/de800 is pretty deep. I am going to simulate some cabs with winISD, and in the end I will build a test cab. |

I'm thinking of a different low/mid driver for the top cabinet. Any reccomendations? The relfex cab will be tw audio m8 style but then 12" format. The reason is because I can place flying brackets on the side for an U brace.

Probably the 12NW76 will be sold and as a replacement I was thinking of the RCF MB12N405. It can handle double the power, and sims better tuned at 60 Hz (almost 3 dB louder). I hope the TH-18 subs are done by next week.

Here is my 18SW115 (135l, 34Hz). Does good job, but will be replaced by 21DS115. Today I got it past Xmax for a while (16,5mm), and even under tuning, it can do a lot, while staying quiet in terms of port or cone noises. It did very quiet friction hissing noises around the surround and wires, so if it played some real sound, it would not be noticable except for distortion of the sound if any. Awesome driver, really. Hope 21DS115 gets me even further. ------------- Nikon and Canon people should not be married to each other. Why did you let this happen? |

Yeah, I'm pretty sure 21" will be absolute "solution" for me for a while.  I'm thinking about larger tops too.

Very interesting system, I have a pair of 18sw115 loaded keystones which are great but I wonder how much you win compared to a small BR cab like yours with close to the same -3dB. Would be interesting to hear your plans for the 21ds115 and 12nw76. I've been looking at the 12nw76 driver and got particularly interested in it when I saw the BR top cab b&c has suggested on their site using it, very strong above 100 |

Date Posted: 23 March 2017 at 4:46pm

I've read that a (good designed) TH will win 6dB over a single reflex enclosure with the same driver. I'm also very curious towards the 12NW76, they have to reach 80/90 Hz. The current design I have for the 12NW76 is tuned at 70 Hz with 30 L Net volume.

Smitske96: It's not because of you saying it, but I absolutely hate that claim. There are few threads on diyaudo, one is even called "case study" about TH being 6db louder. That is very misleading generalization. It only works for certain bandwith without box volume comparison. I.E. per driver maximum performance. But once you check with box volume suited for BR box, and frequency bandwith, TH really doesn't run anywhere. So one should make his choice carefully. Th also has specific colour and distortions. Distinctively different than BR. Generally lower, but again, not across the whole bandwith. I like BR boxes more because of that... ------------- Nikon and Canon people should not be married to each other. Why did you let this happen? |

Ofcourse there are some compromises to be made! But if you would build a cab tuned to 35 Hz, the volume would still be 200 L +-. So a real comparison would be, a cab tuned to 35 Hz with the 18sw115. If the BR cab would come on top in sound quality that's just a + for the BR. If the TH could outrun the BR in SPL that would be a + on the TH. Just to be clear, my comparison is made to a BR cab tuned to 35Hz (approximately). And I am very interested to do a comparison with a BR cab with the same tuning.

I did compared a double 18 reflex with internal volume of 450lit and tuned to 37hz to a TH single 18 with the same driver. The double 18 stomped the TH is every aspect possible.

Bhaha I'd like to see how that one (really small) folds for more SPL, efficiency, usable bandwith, especially for lows, all at once, for basdreflex to loose. Damn, if all that was true, I would not use BR boxes for quite some time. Didn't happen for obvious reasons.

Hallo! I am new to the forum. I would like to made bass reflex for a group starring my son. We have a sound system that is becoming too small. Even given the time to watch the B & C 18SW115 8Ohm. The game is played folk music and fun. I need to carry out live music. By just making will not be a problem. The problem I see in the design. Therefore, I appeal to you if there is any possibility to help me in the calculation of the box. Thank you. Jani

Of course. I compared Cubo12 extended with some 15"s and 18"s, and it also could keep up with bigger guys above 50Hz. You have SPL, size and range, and you always can pick only two in your favor. That way comparing yours with box that can do 35Hz well, is not fair comparison. It simply cannot do what the bigger box can. Therefore it is not generally better box. It is better box for your taste and purpose. And that's good. Nothing wrong about that. It doesn't suit me though, as the performance under 50Hz, and especially under 40Hz, is pathetic. Otherwise I would build THs every time. I will anyways, but for different purpose... ------------- Nikon and Canon people should not be married to each other. Why did you let this happen? |

toastyghost: Yes, I´m aware. I was making a point towards size/SPL/range ratio, and TH isn´t going to break that either. I did Cubo 12 classic, and "superextended", and the second make might work in very hybrid, close to tapped horn mode. It didn´t go low though.

It is tuned at 34,5Hz that way. Could be made 3-5cm shorter for more prominent bass notes. and possibly 2-3Hz higher tuning. ------------- Nikon and Canon people should not be married to each other.

Sure thing, but put two of them together and you have more physical space taken up than a single 18" tapped horn - not by much, but still more space, and double the amp power needed to boot. As ever, you pick your compromises. |

Still in works, while 18SW115 leaves me next week, so I should hurry up, or I end up without audio. I tested it in the 18SW115 development box, and it was promising. So with few Hz lower tune and 60l more box volume, I can only imagine it will get better. I specially appreciate what it could do under the vent tuning. It sill moved a lot of air without noise artifacts, and could vibrate everything around. Depends on what are you after. It seems that these woofers rock for power density in compact boxes. Especially under 40Hz. There is no other 18" or 21" box type that would work better in the same volume. But 21" gets large fast when you want to use its potential, so I might think about something like 12" or 15" tapped horns for next years to come. ------------- Nikon and Canon people should not be married to each other.

Hey. Small teaser. The box is waiting to get home from the "factory". http://www.picfront.org/d/9AQv" rel="nofollow - http://www.picfront.org/d/9AQv With some "padding, it's tuned slightly under 32Hz. Will measure at home what it can do with one or two ports stuffed with cloth... I'll propably make new thread about this as I don't want to exploit this one. Propanly ported boxes department.. ------------- Nikon and Canon people should not be married to each other. Why did you let this happen? |

HI guys. I want to build a compact sub for professional use with an 18SW115. My idea was to create a similar sub type QSub. I was thinking of a box with a volume of 160 liters with triangular reflex tubes. The problem is the tuning frequency. Which frequency do you recommend to ensure good sound pressure like 133-134dB? I have to use it in the live field.
Thanks you so much!

Hey. You don't want to milk one bassreflex subwoofer(driver) for steady output with this SPL. I'm not sure what Qsub thingie is... The driver likes 34-40 Hz tuning. ------------- Nikon and Canon people should not be married to each other. Why did you let this happen? |

| Put it in a decent tapped horn if you need that sort of SPL from one box. |

| The Qsub has an output of 133 dB (peak) and is a box in bass reflex with a lower speaker than the B& C..Also the brand is a guarantee! For the tapped horn, some ideas? I'm open to all options! There is no project for this speaker in the live range (for which it was created) ... |

133db peak is very vague parameter. Seriously. ------------- Nikon and Canon people should not be married to each other. Why did you let this happen? |

| The classic parameter in a data sheet of a professional loudspeaker...There are those who lie and those who indicate a true parameter. None indicates the peak frequency .. |

JAckDR: That´s why it´s close to meaningless, unless we put it in certain situation and usage scenario. ------------- Nikon and Canon people should not be married to each other. Why did you let this happen? |

qsubs are tuned quite high, not much below 40hz.. if you are fine with that a rel. high tuned tapped horn might be the most economic use of a single driver? (if size doesnt matter..) |

Qsub is a shitty box. It that is what impress you, your standards are quite low. ------------- Marjan Milosevic MM-Acoustics www.mm-acoustics.com https://www.facebook.com/pages/MM-Acoustics/608901282527713 |

| I listened and worked with the original and I can assure you that it's not just a shitty box. The timbre is excellent even if the project is rather simple. Together with the satellites of the same series it was a standard for quality live productions ... We're probably not talking about the same loudspeaker ... |

Hi Kyle What in your opinion would be a decent tapped horn, the cyclops maby? I am also looking to get a few cabs made around the similar driver. Mike

keystone subs will go lower than cyclops and are tried and tested with 18sw115s.. |

Almost everything goes down to 30Hz. It depends on the actual power output it delivers at this frequency. ------------- Nikon and Canon people should not be married to each other. Why did you let this happen? |

according to the sims i have seen/afaik/remember, the regular cyclops are not tuned very low.. around 50hz.. the extended version propably rather 40ish hz, keystone regular around 45hz, extended about 35hz? |

Cyclop, TH118, Keystone, all not very big boxes, so 40hz real output with a -3db point at 35ish HZ is what you realistically get from them. For real 30hz performance, you should look at something like the OT horn or similar design. Bigger boxes needed for sure, so it is all a compromise. Once you start thinking truck pack, things get complicated fast. ------------- Marjan Milosevic MM-Acoustics www.mm-acoustics.com https://www.facebook.com/pages/MM-Acoustics/608901282527713 |

| I am not so experienced as you guys here but if 30hz is needed wouldn't band pass cabs be better to use, maby X1? |

Better is also very broad term. It gives out great SPL for one box, but has also many disadvantages. ------------- Nikon and Canon people should not be married to each other. Why did you let this happen? |

Standard Cyclops has 40hz with Fane Prime even though Staip said 45. Has a very reflex sound. Not an enjoyable build, think about getting bracing in, need a carpenters mind, or one better than mine :) Very high attack and subby cab though. Only time I have ever liked sound of non reflex cab in small space Sadly the FSP link is broken. Link below (the builder) was me. https://forum.speakerplans.com/beware-the-one-eyed-monster_topic39393.html" rel="nofollow - https://forum.speakerplans.com/beware-the-one-eyed-monster_topic39393.html ------------- It's everything, not everythink! |

| Hello I know this may be late but did you make the box yourself. Cause I am also interested in the driver and I am looking for the best of both worlds that is the best sound with the smallest possible size and weight. That's why I like your box. Please if you didn't build it yourself who did. I am based in Maryland and have been trying to get a good box builder. Any help will be appreciated |
