Home Audio Speakers

Normally home theater systems support high channel audio. Say 6 channel Dolby or better. So 110w/channel is quite high (660W right there). Now the receiver has to have pre-amp, possibly radio receiver, and equilizer functions. These are low power applications that are highly susceptible to noise on the power rails and EM noise generated from nearby high power circuits. To properly shield the low power functions, supply power to all the functions, and then properly COOL the whole system down is a large engineering effort. People will not pay the $$ for the increased complexity that providing huge power support will cause to the whole system.
For high power applications, you are much better off (quality/$) to go to individual components and purchase a pre-amp, with a high power amp.
You could purchase a good quality low power theater receiver, then use the pre-amp outputs to amplifiers that support the type of power you are looking for. This will give you great quality high power output, at an audio quality dependant on the pre-amp (theater system) you choose.
