Same as usual MrGsR:
Eminence 3015lf, 18Sound 14W700, JBL 265H-1, P.Audio C15-600EL, RCF L15-200AK....
But I think you need an extra piece of wood for this. The idea behind the design is extended LF (at cost of 3dB max) and it should match with an original SS15 and both can be powered with a standard 900watt/4Ohm amp. The total response of the two together should equalize the dips and peaks with no fase issues.

Just took a look at the driver mentioned in post #964 which is a 12" woofer sold by MCM it looks to be an intersting drive. However I saw Dan's comments about T/S data and MCM drivers. Has anybody bought and measured one of these woofer and are they close to the stated specs? MCM # 55-2982. thanks and best regards Moray James.

ok im trying to get to grips with Horn resp using the ss15 but ill be honest, i dont have a clue where to start.

I tried typing the parameters that i found in post #54 but i dont know what other setting i need to adjust because its not as straight forward as copying the numbers.

Im trying to find out if the

18sound 15NLW9400

will work in the ss15. I have a couple of these winging there way to me and im really hoping they could be a high power upgrade over the 3015LF.

They are recommended as such for the t48 so if they dont work in the SS15 then i will stick them in a couple of t48.

Of course i would rather be able to model the speakers myself...

Default SS15: 3015LF_v_15NLW9400

Hi Dave NonZero,

Here is the 18Sound 15NLW9400 stuffed into the Hornresp input from the SS15(3015LF). Maybe you can optimize the design from there.

Regards,

Yea it's 25lbs instead of 10, but it's within a db of a 3015lf in output, and half the price.
...while exceeding xmax by 3mm, no? I believe you have to reduce input power to 200W to bring the displacement to the rated/published xmax (which in turn brings down SPL quite a bit...).

If all of the sub-$200 3015LF's go bye-bye, I think the next best bet (response wise) would be the RCF L15P200AK 15" Woofer at $259/ea or even better, the 4 ohm variant -- IF you can find it in the states.

run the hornresp for the kappa pro 15lf... it runs lower xmax while producing within a db of the same sound. It stays within xmax at 63v
