mono amp for sub

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.

In a similar situation and wrestled with this. Used 1 channel of a cheap Sony stereo which worked pretty well. Tried a DIY plate amp, not enough gain control. Found that a straight amp and the prepro's lfe +/- adjustment wasn't enough. Was leaning towards proamps (crown, qsc, etc) with a gain adjustment. I also used a good quality car audio amp I had around (hifonics zeus) with a 12vdc power supply, worked well but clumbsy configuration...

Here's what I have coming and I'll let you know how it works out.... I bought a Buttkicker amp. Class D that only responds in the 10-200Hz freq range. Said to put out 1100W into 4ohm (way more than I need or the sub it rated for) and is said to be 2 ohm stable and double power. It has the crossover and volume level control.

email me in a few days or maybe I'll follow up with how it works as a sub amp.
