Thanks dsrussell, JT and tvuong!!
tvong, I wont keep asking setup questions in this thread, but I do have one clarification question for you based on your post. You suggested using the line in on the sub if my mains/center can handle below 100hz (which they can... per Aud XT32, at least down to about 40hz... I know my surrounds go to about 85 hz). I was under the impression that the sub falls off on the high end pretty quick above 80 hz using the line in input, but goes up to approx 200hz using the LFE input. I guess I am wondering why anyone would want to use the line in over the LFE input? ... I dont see any benefits on the surface (but I am first to admit, I am no expert, and have not researched). If I am crossing over around 80 (I am guessing 60-80 will be where I'll end up after I get the sub in place), am I not better letting the sub play up to 80-90hz (vs my PSB main towers and center?) Seems like using line in, if I cross at 80, and the crossover is gradual, and the FV15HP falls off sharply, then might I be missing some of the impact frequencies in the 80-90 range? It is probably no big deal, I guess I just dont understand benefits of using the line in input over LFE input. Thanks again.
