mono amp for sub

KGvet,

I was in a similar situation to yours a couple years ago when I decided to try a better amp on my NHT SW3P. The NHT SA-3 mono amp wasn't cutting it. I also considered the Bryston 7B, but opted for a 4B instead just in case I decided to do a dual sub DIY. I still haven't built it.

I'm still using the 4B, and just one channel is much better than the NHT amp. Maybe you could go with an older 7B or 7NRB which should save you some cash as opposed to getting a newer 7ST or 7SST.

Otherwise, the Crown amp idea is a good one.

Good luck.

Not sure why you would want to waste an amp like the Bryston in the first place, subs need no such amp.

I use an Onkyo M-504 to drive my Vmps subs...over-kill to say the least.

Rooze...I use CarverPro zr1600 amps for my subwoofers, and they certainly do the job. One advantage, for a SW, of the zr1600, or any digital amp, is that their efficiency is very high. Much music has no signal content in the SW range, and where the music does have such LF content it is usually only for a small portion of the time. Digital amps draw almost no power when there is no signal.

That was my point although you said it much better. My Onkyo M-504 has large power meters, at 60hz. and below my Vmps subs hardly draw over 100 watts even at extream volume levels. Those power levels are peak at that!

90% of music is in the 0-50 watt range to be honest.

Something like an $2,500 Bryston for that limited freq. range is a waste of money IMHO.
