Re: adjusting gain & subwoofer tuning

Honostly, I have my gain on MAX for my subs and speakers, some say it's not bright, some say it's fine. I do this because with the gain knob all the way up, my speakers and subs get louder FASTER, and Infinity Kappas and most other acoustical speakers sound horrid without the gain up (unless they have a line driver) so I always keep the gain up on those, don't really get any distortion either.

the distortion you are getting is inaudible to the untrained ear. it is called clipping. it is the number one killer of speakers. on an oscilliscope it looks like DC power. a square wave. so if you look at a square wave, the woofer will move out and hold that position building up heat for a period of time, then move in and stay there. it does exactly what the wave looks like.

i dont have time to explain this in detail, so look here:

So if one of my speakers was "killed" how would I notice it? I would assume no sound or bad sound would come out of it, correct? It's quite hard to notice it right now I would assume mainly due to the interference that I'm getting (which should be solved tomorrow). I will turn the gain down to half way just to be safe.
