Home Speaker Asylum

General speaker questions for audio and home theater.

RE: The 10" drivers have an Fs of 30 hz, 8 ohm 90db.

Timbo:

I think you should try the HK as you have planned and see how it goes. See how "tight" the bass seems... of course, there is more to it than just response. Just look for signs the HK is struggling... one is distortion the other is excessive heat.

I read your other post... you have lots of copper going into that room so voltage drop should not be too much of a problem. Running big amps on their own circuits is always a good move. I suppose it could be fun to switch amps and boxes to see how things sound. It is tempting to put more power behind the drivers that have higher xmax... but it's also important to know if there are any potential issues with "unloading" of the sub driver, aka where a subsonic filter should be used. Super-lows just rob amp power and move the subs voice coil out of it's sweet spot, as far as it's B-L curve is concerned.

I am not aware if you have a preliminary plan for placement. There are theoretical "optimal zones" to put subs in multi-sub applications for the flattest response (most even excitation of different room modes).

For two subs, I think it was one in a corner and one on the center-line of a given wall. My understanding is that mirror image location of subs is *not* necessarily an optimal layout.

Cheers,
Presto
