Ahh, yes -- you are correct. I've stated several times that everything all 'falls apart' (meaning power compression, out of xmax, cabinet at limit of what it can take, etc..) all at about the same time on the ss15 -- I call that good engineering..... or maybe just getting darn lucky...

This is designed as a 500 watt class sub, using cheap eminence drivers, that can be knocked together in an afternoon, that weigh a fraction of a kilowatt class commercial sub. Where I hang cabinets... My back likes me better.

It also just happens to put a smile on my face when I crank up a pair...
BTW, peavey IPR's with dsp... and using the integrated maxxbass for HighPass is interesting. (hint)

Hint?

Awe man!

Funny part between 500 watts and 1000 watts is that there is not a very noticeable difference in SPL, especially when they warm up.

Ohh I wasn't knocking the cabinet at all! You know I loved mine for beach radio duty!

I was just saying they have their place. Maybe not in this cabinet, but in others for sure

Anyone need a 3015lf? I have a spare for $150 shipped in the US. I don't NEED to sell it hence the lack of FS thread, I just figured I'd help out someone looking to build a cheap ss15!

does the SS15 like being ran via a compressor? people are telling me i need a compressor to get the most out of my subs.

ive always thought that a more dynamic signal (ie: biggest difference between hi and low amplitude signal) was better. rather than compressing it and losing the dynamic range.

if im wrong, please learn me. otherwise, imo, i cant see why i would "need" compression to make them sound "good" coz they already sound great to me.

A compressor can be useful in certain situations.
If over-used the increased average levels will just overheat your speakers.
Fortunately for you as you have found out with your 4 X SS15 cabs the difficulty is getting the mid tops to keep up rather than the bass!
Some compressors can be used as a limiter just to knock off any transient peaks that would cause clipping - Digital crossovers usually have this function built in. This can gain you a few DB of volume.
I have used a compressor in the past with moronic DJ's who seem intent on blowing up the PA - I found an old school Behringer MDX 2000 - 2100 works well and sounds good. You can set up a gentle compression ratio and a clip limit - The clip limit on these compressors then adjusts the compression threshold downwards when the rig is overdriven. This is a very useful function especially for those all night gigs when you dont want to be tied to the rig every minute. I also have a Drawmer MX30 compressor on which the clip limiter is very harsh in comparison with the MDX 2100.
These days I usually use compressors to manage dynamic peaks on individual channels of a live mix, to fatten up vocals and limit drum transients.

Default Complementary subs.

I have rounded up two 3015lf's and am making a pair of SS15's. I was planing on constructing four but due to a amp upgrade I now have 850watt X4 to throw at them, should I just use the definimax or B&C drivers in the next boxes or is there another design that would be better suited to more power that could work with the SS15's.

4015lf is a very respectable driver and works great in the ss15.
A pair of lightweight 3015lf's and a pair of heavier 4015lf SS15's would be a nice quad stack.

Most of the interesting things that happen with subs happens below 500 watts in my opinion, as that's the tipping point where losses really start mounting. I don't try to make any of my designs really work at the multi-kilowatt levels.
