gain is different from input sensitivity. You can never remotely accurately compare power of two different amps with their separate volume controls set at about the same place. Musical instrument...

Digital bolume controls are cinfusing. Assuming the receiver goes to 100 as currently configured, at 80 (20 dB lower) you are using one one hundredth the power you would use at 100. Iow you are a...

The mbl is exactly what I was thinking about. The primitive part of my brain expects them to expand or morph into Star Trek mankillers. Probably the sex would be good til then, though

Well. "obviosuly" (at least according to EU regulators) if you were to run the amp with all channels at full power without any limiter for a couple of hours or so, it could get hot enough to create a...

go to, like, Stereophile.com, and look at testing for amplifiers. Every amplifier in the world will exhibit 0.6 or 0.7 percent THD at some power level. In fact, unless it has very significant power...

First, if you have enough power to get as loud as you need to without audible distortion, having more power will never make a difference because you never will use it. Ohm's law guarantees that, in...

The advice above is spot on. just my 2 cents. Almost certainly your problem is not the receiver. all the bass power comes from the sub's amp. Even at 2 volts output (the high end for a consumer...
