Asked Staip to extend the depth to 700mm, built it and tested it and here it goes..Amazing sub...loaded them with SD18ELClapClapClap

.. loud, heavy and clean..no movement of any sort was noticed on the bins during the testing, even the RCF on top stands still..lovely

Looks like a nice rigid cab you built, very pro. I like it that more and more people router their own handles in the wood like you've done . It looks wAAAAy better,  allows for lifting in multiple directions and it's cheaper. Nice job.

On the the upper freq 186 and this bin well I would almost behave similarly but on the lower end its getting flat at 40hz and even lower in single. It will do its job even the eq is flat.

Hi, Is there a drawing for the 700mm model? Can this be expanded out to 900mm or 1200mm deep for a Super One Eye Monster???? Thanx, VECTORDJ

I am sure it can. But you will win some and loose some.
It will go lower but at SPL loss i think.

In fact there are drawings for few slightly modified variants every made on specific demand.

1. Standard CB-18
2. Extended front CBe-18  (streetsounds version, 700mm deep)
3. Full extended CBX-18 (extended pathlength, front and mouth area) - made on demand for extra few hertz LF extension

+ there is also standard CB-18Light version plans for 15mm plywood (extralight version ... as much as it can Big smile :) )

Ofcourse it is possible to make to modify design to suit some new goals but all comes with some compromise .. If you want additional LF extension in compact size ..SPL suffers, If you want booth , max SPL and LF extension too cabinet size goes up rapidly.. etc :)

It is not big problem to make one "monster mega, giga, cyclops" but than size and weight will go much out of margins of regular "usability" and muscle and spines will hate em (however may be good for showing and shootouts)

I have thought about Cyclops idea to be good bass solution with "ideal" bandwidth for most jobs (flat ~40- ~130Hz), pretty easy manageable size and truckpack friendly. Any further increasing size (more than CBX-18 version) will go out of this goals.Broken Heart

Thanks Staip for tweeking the design a bit as I requested. I cannot ask for more  after hear the first testStarStarStar. Its not that heavy anyway as I expected and can still be easily managed mobility wise.

Well may be, I was thinking, the reason why its not moving at all even when playing  heavy bass is because of its symmetrical design.. additonal plus factor

I could not able to test it fully, neighbors are screamin', but even with a very small volume adjusment you feel the bass. With just 2 cyclops the bass was intense., I just noticed the driver cone moves a lot, Maybe i need to high pass it to around 40 to 45hz

-------------
Bass matters...


Posted By: staiper

35Hz L/R or Butterworth 24db/oct will provide enough mechanical protection even on highest power.
If you feel that you really passing safe margins you may set it up to 40Hz.. above that there is no more point of rising HPF to protect driver , only reason for further rising may be to "preserve" some amplifier power headroom.

Also to note it is not good to completely minimize or "kill" cone movement as it is very important for voice coil cooling / air flow around VC gap and through magnet structure.
By totally reduced cone movement it is much easier to fast increase power compression and turn speaker unit into audio driven heater and under that conditions it is easy to burn voice coil as you cant hear any distortion and its sound level seems lover (and it most likely really is.. due to heating/power compression)  than you used to use before.

Some companies especially for bass cabinets intentionally recommend lower HPF filtering points that theory suggests as safe to improve that cooling effect by intentionally allowed bit of extra-excursion  (but for that they select or design drivers so they can be confident that mechanical damage point is still far from voice coil "reach" and that extra bit of excursion do not make unwanted audible noises)

BTW .. only on very close listening , most of bass drivers on back side may produce slight air "chufing" tones by the magnet pole-hole. This may be audible only on close listening a.k.a. "head in speaker" and it is not audible at all and will not affect sound when you move even 50-60cm away.
..just in case to not confuse this with real "cone farting" Wink

Best wishes, Stipe

Yup I did it last night Stipe killed freqs below 35hz and low pass it to 140hz. I rigged it up with the live band and with just 2 cylops a side the bass was amazingly intense, finally managed to tune it properly. Its a very efficient box I would say, small amount of power exerts lots of bass. I could say that this is a "power amp friendly bass bin", you dont need to push the amp that hard to meet the bass you want., I think this CBe-18 will outrun many sub bin design..but thats just me. Thanks for the design and for the tips Stipe.

Yup some sort of a DIY midtop. Thats a double 12" mid with hi comp driver at the center similar to mT 122 but shorter and deeper. Drivers installed are 2 PAudio C12 500MB for the mids and PADE99 for the hi.

hi streetsounds, 2 questions

which one has a higher spl, your cb18 or the subzero?
which one has a deeper bass, cb18 or subzero?


Posted By: streetsounds
Date Posted: 12 December 2010 at 2:37pm
These CBe-18s will definitely outrun the subzero with regards to SPL and musicality. It can also go deeper.

Im not a reflex user so I dont have that much idea how to compare these cyclops to the reflex bins, but I think these CBe-18s, recalling from what Ive heard from a reflex cabs before, are far better spl wise.

Hello Frad,

It grooooows Clap 

Wanted to ask some question which may also be interesting for other CB-18 owners/builders.
As you already have pretty neat stack of CB's and worked with them on real gigs what is your opinion about CB-18 bass "directivity/throw" .. one of builders have have said that he have pretty nice front-to rear SPL difference described as almost "cardioid" bass coverage with them so I wanted to ask you if you have any observations regarding this.

Best wishes

Well I think the same with me here very good throw at front, waste no sound at back and at sides..but just enough for the band to feel that something is pounding hard and heavy at the front. Ive used them just 2/side in an almost 2 basketball court size semi open gym and still can cope. One more thing ive notice unlike with previous bins that ive used, stacking them in stereo, the bass is almost even at any point at the front, it seems as if you stack them all together at center.. so I think the other builder that you are mentioning is quite right. Now I will try 3 per side and see hows its like Wacko

Nice build. Are there any specs of all this 3 types of CB-18 cabs? I'm interested in building some but would like to now their usable pass band and sensitivity.

Also the tapped horn design as far I'm aware of does not couple (like a normal folded horn) when used in multiples. Is this true?

You can low pass this bin at 35hz and high pass it at 120-140hz, but Ilike it at 120. During our testing (single bin) it registered almost down to 38 hz but that just a software from an ipod.. I think we can ask staip for the horn resp simulation.

For a CB-18 you need 2 sheets (244x122cm) and you'll use almost the whole sheet.

So I think you need 2,5 of 3 sheets for the CBe-18.

Hello Stipe
I've just finished painting and loading 2 CBe-18 cabinets and thought you would like to see some more of your design in a finished product  You can see the whole project at
http://www.facebook.com/album.php?aid=2081972&id=1008565733&l=c96d644b96 (hopefully this link will work)
I'll be testing them out early next week in a club
I have already run a single sub for a test and was very happy with how musical it was  how directional it was and the amount of volume that came from this box The speakers in this set were from a company here in the states similar to a JBL 2240 That's what I had to work with for now but will take your suggestion and load them with RCF Thanks for a great design looking forward to building 6 more

Thank you and again I thank Stipe for providing the great designs and sharing his knowledge (The best things in life ARE free)  I live in Western NC outside of Asheville  and the paint is Rustolium truck bed liner from Advance Auto Parts $59 a gallon and applied with a $19 Harbor freight texture paint gun at 10 lbs psi   As Marjanm said "cleanup is a PIA but worth the outcome.         

 http://www.harborfreight.com/catalogsearch/result?category=&q=texture+paint+gun

took forever to find the right combination roll on 2 coats let dry and spray 2 light splatter coats Be patient (not like me) and let it cure for a few days before stacking

Getting the finish right was always the hardest thing for me

Your not that far from me.
Im in Huntsville, AL. Been to Asheville a few times.

Haven't seen the Rustolium brand bed liner.
Have used both Duplicolor (which you can get in a spray can for touch ups) and also Rhinolining.
Rhino was the best but cleanup is a MPITA.
I have used Duratex also. Better on cleanup but not any cheaper.
Bear premium. OK but not quite it.
Gonna try Cement paint next. Well gonna do a small piece test first.

I use the same gravity fed gun btw.
Paint and then spray twice.

I will eventually build a cyclops to test out.
So far I have built 3 different TH's (Mini clone , Apache , and SS15) along with a few one off builds.

The Mini TH Clones? (not scoops BTW)
Per size nothing comes close to beating it. Clean and loud. If those B&C drivers were cheaper I would just have built a bunch of them.
As is I am just finishing up 12 of the SS15's.
They dont go as low as the Apache/FurySub but cost,size, and weight won out.  Should be putting the grills on tomorrow and touch up paint should finish them off.  Will post some pics over at DIYAudio on the Single Sheet thread when dont.

I used Duratex again.
Rolled then sprayed twice. I really think it needs to be rolled 3 times then spread twice.  Wont get a chance to test the cement paint for a few weeks due to work schedule.

The subwoofer can be adjusted without altering the external dimensions of the loudspeaker enclosure, utilising the entire volume of the loudspeaker enclosure, so that the frontal chamber is tuned by altering the size of the frontal chamber and/or the size of the aperture in the frontal chamber.

So we aren't building it like the diagram shows?

Looks like they are trying to run a con-job on WIPO, and hoping they're small enough to escape notice otherwise.

I'm not sure why Klipsch referenced this 1952 patent in their patent #4138594, but the Danley TH looks like it works on the same idea as the 1952 patent.

You call that A18 box a SUB???? -10db at 50Hz. LOL

And all that marketing mumbo jumbo patent blabla horn loading in a special way
 but only 100db at 1m. What a joke.

* Sensitivity, 1w/1m: 100 dB (free space) *
you know what that red part is about, rite? Tongue   ( = 103dB@1W/1m/2pi )

Anyways, seems like a poor approach on a commercial knockoff of the "cyclops" design with its -10dB@50Hz. Though the box is quite small and light, but who would choose a TH for kick duty over a BPH (like ES18 or HD15) - which deliver equal or more output per input, have better phase response, and are even smaller? Confused

djk, thanks for doing research!

No, seems that they do not build their subs like the diagram shows LOL
When you look at the whole publication you can see that they have tried a lot of different enclosure variations including a type of enclosure which is very similar to a tapped horn...

The whole patent publication:
http://www.wipo.int/pctdb/images4/PCT-PAGES/2010/482010/10136639/10136639.pdf - http://www.wipo.int/pctdb/images4/PCT-PAGES/2010/482010/10136639/10136639.pdf

Attached sketches of different enclosure types:

http://www.wipo.int/pctdb/images4/PATENTSCOPE/101/b4/cc/06b4cc.pdf - http://www.wipo.int/pctdb/images4/PATENTSCOPE/101/b4/cc/06b4cc.pdf

...most of them seem to be some kind of 4th order bandpass designs, Marjan already spotted the low sensitivity specs referring to their old 'subwoofer' designs, ie A18 Sub, etc...
Anyone ever tried to do a flh with a chamber in front of the mouth???


But there are others as well, who try to run a con-job:

http://www.wisdomaudio.com/pdfs/S90i-Manual.pdf - http://www.wisdomaudio.com/pdfs/S90i-Manual.pdf

...in the manuals you have a very nice plan so you don't have to guess what's going on inside the RTL subs, more a horn as a transmission line imho Wink

If i'm not wrong, this was partly designed for Aura's biggest sub.

I haven't heard their design but they seem to be quite proud of new XD range. I had a brief talk about it over phone with one of Aura people but didn't quite get it when he told me about the loading. They were quite happy specially about how fast it stops ie. doesn't reserve too much energy. Aura sells BMS, 18sound, Faital, PD and Fane so I contact them every once in a while.

There is quite much of Aura stuff in use here in Finland and general word between sound engineers is that while it is not d&B / Meyer / L'acoustic it mostly gets the job done, just. Subs (the new range I guess) are generally thought being better than midtops and monitors. I have mixed on Aura once and heard it few times. A8 has bite that is not what I'm exactly looking for. I have not got recent memories of it though.

Wow, can you imagine a tapped horn with almost the same size of a psyco bin driven by an 24inch precision device!!?!
Must be amazing!

Found a trick for conversion for mm to inch If you are math challenged (like me) You can use Maxcut to enter all of your dimensions in mm and convert to in.thru MaxCut all by using the toolbar- imperial/metric function all in one click

finally have some cash to purchase drivers to build 2 CB-18 not the extended version.  trying to decide on what driver to purchase seeing i am in the states and i have a budget of $250 max per driver.  now loudspeakerplus has the SD18 but i am confused on what version.  the specs and picture show the old version, but the more info link shows the upgraded version.  i will probably have to contact them.
http://www.loudspeakersplus.com/product/SD18/P-AUDIOSD18/

i was also looking at the C18-650el, but not sure how well it would perform
http://www.loudspeakersplus.com/product/C18-650EL/P-AUDIOC18-650EL/

what about the peavey lowrider
http://www.peavey.com/products/speakers/proaudiospeakers/index.cfm/item/117174/18%22LowRider%26reg%3BSubwoofer.cfm

or maybe something from Selenium.

the B&C runs $300 with free shipping.  i've thought about those drivers.  i'll have to save up some more before i can purchase anything over 250.

my goal is to build a pair of cabinets that will perform better or equal to the sub set i am currently using.  i use 2 peavey SP118 with the 1808 drivers and 2 older peavey 118HC.  nothing fancy by any means, but this set up is used primarily for live band applications.  my amps are QSC RMX2450s.  i have plans to build 2 more cabinets in the future for outdoor shows.


Posted By: MarjanM
Date Posted: 06 August 2011 at 11:25am
B&C and 18sound drivers are top quality. How ever i am not sold on Faital fancy look and marketing. I have a friend that is still arguing about his damaged 18XL1500 with the USA distributor. The wire lids from the basked to cone have broken at half after 3 months of use. Clearly a design flow that they wont admit.
