Ive searched through the thread and only found i few 4ohm driver recommendations.. Any thoughts on which driver to match the design like the 3015lf do? Have been looking at the B&C 15NDL76 & Fane collosus 15XB. Im not too bothered about the weight, as long the box is getting the highest spl possible. Am I on the right track or would other drivers be a better choice?

I have a feeling the 700W quote is from the test I posted, where I mentioned the output figures were just at clip/limit light.

I did some quick amp tests (also posted in the TH-18 thread) in briged configuration and found the voltage out was less than half of the rated power with the clip limter engaged and the clip/limit light fully illuminated (heavy into it).

When I measured my SS15 just under clip (light flickered), the amp was not bridged and the clip limiter was on.

Just food for thought (and I hope to test with SPL AND actual voltage numbers the next time)

After doing plenty of research on different ideas for a PA subwoofer, I landed here. I tried jumping around from the first page, but decided to skim all 166 pages. Now that my eyeballs can focus again, I decided I needed to post up...

First: Thanks to all involved! This is a great project with a lot of community support.

Now then, I feel a bit confused on what design to go with. There seems to be ~3 versions of this...
1. dbell's original (post #53)
2. Djim's "extended" (post#691)
3. dbell's "SS15v2" (post#1499)

Is there a comparison of the 3 directly? I saw some original vs extended comparisons... It seems the v2 is pretty new and I don't think I saw it tested? Sorry, if this information is all pretty available, I'll be happy to go more read-happy on this thread... just took a long time just to skim through all those pages! Or perhaps, a general consensus on which one to build?

I just to hate to build one to find that it isn't as solid of a build as another. Thanks for whatever information can be provided.

Hi there: Which one you build depends on your requirements. #1 JBell's origional is flat down to about 45hz, #3, JBell has tested his v2 flat down to 40hz. #2 Djim's extention of the origional SS15 is considerably larger and his posted tests show a reduced band width from the origional SS15. Numerous people have constructed the Origional SS15 and according to their posts are using them on sound reinforcement jobs. Since the SS15 is easy to construct and uses (now more expensive) driver 3015lf, you can build one ( or one of the each) and judge if the performance meets your requirements. ...regards, Michael

The original works so well -- just build that.
Use the 4015lf if you plan on abusing it.
Use the kappa pro 15lf2 for a budget, lower power option.

If budget is concern, I'd rather have a pair of kappa pro loaded cabinets, vs a single 4015lf cabinet.

32hz 24db/oct high pass. The high pass is not an option.
