L4Z3R37H

I did not clarify that I use 12 gauge speaker wire throughout my HT. Except for the sub RCA. I have been experimenting with the Bi-Amp feature, and my receiver did an excellent job trimming the channel frequencies after going back to the single amped L/R setup. There really is zero audible difference at normal listening levels. Even at higher levels where I comfortably listen to music, there seems to be a little more head room at the minor expense of a "fuller sound". which makes sense, but really isn't important. I watched JJ abrams star trek today, and with all my speakers set to small, and the sub x-over set to 100HZ, I don't seem to get any muddy transitions. My Center is a joke. My Klipsch 10" front fire sub does seem to "flubber" without the punch, compared to my melted 12" down firing Polk sub. After having both kinds of subs, I'm more impressed with a down firing sub, vs the current klipsch front firing. I intend on purchasing a new plate amp for my polk, and dual subbing.

I have a polk audio PSW125 down firing sub that I used up until the plate amp took a shit. I could shop for a new panel amp and use it...And in your opinion i should not bi amp the fronts, and run them at small. what do you recommend for the crossover?

I Own a Pioneer Elite SC-63 receiver. I recently purchased a set of RP-250F floorstands for my front left and right channel. I use the R-10SW sub, a Polk audio RM8 Center (budget, junk) and 2 Polk RM8 satellites for surround (chose them for the bi-directional cones, and budget) overall, an introductory home theater with an adequate sound field. My receiver has a feature called advanced MCACC, where i simply plug in the provided sensitive microphone into the receiver, place it at center listening position at ear level, and the receiver does all the dynamic adjustments for acoustics, distance, channel volumes and so on. It does a great job with the distance and channel volumes. The receiver is capable of bi-amping speakers with such an option. I use the top poles of the floorstands with my left and right channels. (yes, I did remove the brass couplers). The receiver specifies that I use the surround-back channels to bi-amp the bottom poles of the floorstands. I'm almost certain I have this setup correctly. I've also went into the receiver menu and setup of the front L+R channels as bi-amp. the final setup for my HT after the full automation MCACC: Front left and right: Large, Bi-amped Center: Small Surround rears: small Surround back: supplemental Bi-amped Front high: not used Crossover frequency: 150Hz I have 2 LFE sub outs: I use one LFE out to the sub, the LFE is rolled all the way up on the sub, and the gain is rolled back to about 1/4-1/3 of the way from zero. (any more, and the automation complains that the sub gain is too high) my problem: Front channels set to large...Is this right, considering I'm bi-amping? and the crossover frequency set so high? 150hz seems high considering the capabilities of the floorstands. Also, will my rear surrounds suffer if I bring my crossover down to 80hz? I know the receiver is much smarter than me, however when I'm jamming to zepplin or frampton, I use the EX. Stereo option on my receiver. This in my opinion, creates the most magnificent sound field in my living room, but I'm afraid my satellites will suffer from the lower crossover frequency. I listen to music at moderately high, to holy shit volumes. P.S. When I watch a bluray, Such as The Avengers, or Dark Knight rises, I aim for sharing my home theater experience with the neighbors on the backside of my property. I want to experience the Hulk, smashing.
