To give some idea of this club:
Then: 6 CV 15" 3-ways for tops, two CV 18" FL horns for bass
Now: Rented equipment - 4 18" "scoops" (loaded with BNC drivers) for bass, tops unknown - some DIY design from Trinidad loaded with a 15", a 10" and a compression horn. A WT3 test on the scoops suggests that they're turned to 35 Hz.
What they're currently considering: Four of the previously-mentioned EV 18" subs for bass, and rebuilding the previously-mentioned CV full range boxes.
I suspect that the EV 18" subs may be a step down from what they're currently using 🙂.
I'll mention your ideas to him.
Tell him to build (2) Berta's with the mouth extensions (Levan) Insane Bass from them!

Personally I don't think the ss15's will be enough for a club considering the tuning...Many songs will have content below the tuning and can kill the drivers pretty easily (without proper monitoring of clipping etc)

How many litres for how many dB SPL?
How long is the horn?
To what frequency does it hold flat?

Yes, the SS15 MUST HAVE it's highpass. 32hz butterworth 24db/oct minimum.
Yes, dnb, etc has content below 40hz that may be needed in a club. However the first thing that is requirement, is that the brother needs to be convinced of the advantages of TH. Only when that is accomplished can he start considering what low cutoff and spl targets he wants to achieve.
Ohh I kno about the high pass on it. But even with it set up, on a heavy bass track with a DJ pushing the system for more output, he will probably drive the amps to clipping not paying attention etc etc. That's what I was referring to. I guess I was saying it from
More of a headroom perspective. It's better to have more headroom and not worry.

ahh... got it... 4015lf and brickwall limiters help with an aggressive dj for an ss15.
The best defense (even makes things kid proof) is an XTI amp with everything in one chassis PASSWORD PROTECTED.

Hi there, Brian Steele i'm from TRINIDAD the DIY top from Trinidad loaded with a 15", a 10" and a compression horn.Is a copy of the EAW KF850z top
Thanks. It is an identical copy (e.g. same drivers), or is just the box built the same as the original and different drivers are being used?
One of my brothers indicated that it lacked midrange, but that may be due to "boomt-iss" tuning by the DJ (if you're really a trini, you'd know that term, LOL. The non-trinis here should be able to figure it out 🙂). I wasn't in the club long enough to have a look at how they were being driven.
BTW, sometimes copying (or rebuilding) a commercial system may raise some interesting issues - see my attempts at rebuilding the CV tops here - So, my brother brought over 4 blown Cerwin-Vega Pro Stax PSX-153 speakers... - Techtalk Speaker Building, Audio, Video, and Electronics Customer Discussion Forum From Parts-Express.com
Hi, that is certainly a nice price, and your simulation also looks good.
I've found a few places to buy these, but I can't find any T/S or other detailed specs on these. What data did you use to simulate it? Or where can the data be found? Is it official or measured?
At a woofer this price, it's probably best to invest in a woofer tester to make sure the parameters don't deviate too much. But at 1/4 of the current price of the 3015 (50% price hike - ouch!) that's definitely in the budget.
Hi guys, just thought id share my SS15s!
sorry for the bad ones.
the only issue i had was that my sheets are 1200x2400 not 8x4 so its slightly less deep and a smidge short. but they still sound awesome! cant wait to flex them on the weekend.!

theyre the drivers out of a pair of DJTECH branded active subwoofer cabs. I was emailed the t/s specs that i used to model the driver in hornresp. Ill post a response curve later. Theyre about 350w rms... And im about to push them with 1200. See how long they last...

Aww yeah, that's what I call an upgrade. Don't forget to post a shot of the cops when they show up!!! 😀😀😀
You got the filtering to protect the setup?

Brian they are not an identical copy some times the drivers & the built are different (eg the original use a B&C 10" with a phase plug and wave guide)
iv got a filter on the amp, its a 30hz cut, i should probably use it, but they just dont sound anywhere near as phatt with the filter active. i guess at higher volumes the SPL will more than account for the lack of <30hz...
I find similar when I compare domestic listening with different roll-off frequencies.
Lower than 20Hz by a factor of 10 sounds better than lower than 20Hz by a factor of 2, i.e. I can hear the difference between F-3dB =10Hz and F-3dB =2Hz.
My speaker specification says I should not be able to hear that amplifier difference.
F-3dB=30Hz is seriously altering the audio spectrum response.
But, which is more important contended paying customers or broken equipment?
