I recently added the PL-200 as a second sub (using a y-splitter) for my Onkyo 7100 (606 receiver and htib speakers). I placed the subs doing the "sub crawl" then ran audyssey with each sub at about 1/2 (PL-200 a little less than 1/2, Onkyo sub a little more than 1/2). about I get a lot of rumble out of the PL-200, with some support from the Onkyo sub, but the mid-bass is completely missing. I have the PL-200's crossover off, and Audyssey has set the sub LPF of LFE to 120Hz, the fronts and center to 80Hz, and the surround and surround rears to 100Hz. My question is, where the hell is the mid bass? Kicks and snares and stomps do not sound off at all (only through the fronts, minimally); I mainly hear the subsequent rumble. It sounds ridic and unrealistic. Does the PL-200 just suck and not pick up the upper frequencies? What changes can I make? This lack of mid bass is annoying as hell, and just off-putting. I actually think it sounded better pre PL-200, even though there was minimal response at the lower frequencies. I also posted in the acoustech owners thread. Please help. Thanks.
