Hi all! I was wondering. When used on an HT, the receiver does all crossover work in the digital domain, sending low frequencies to the sub and high frequencies to all satellite speakers. I don't use my sub like that. I have a stereo amp with no crossover, and run a line-out cable to my sub. Basically, I'm running my main speakers unfiltered, and use the crossover sub as a low-pass filter. What if I decided to use the hi-pass line filter on the 300-794, therefore having a hi-pass filter to my speakers? I have thought about it, but I really don't know much about the quality of that filter. Is it of a good quality? Should I just still run my system's main speakers unfiltered to get the sound quality...? I'm not really sure... Thanks for your help!
