After doing alot of research (mainly on the forum pages) on the issue of bi-wiring Polk speakers, I decided to let my own ears tell the story. Glad I did too, 'cause the way most bicker about the subject in the threads would confuse the novice....not that I'm in no way a pro at sound, but I do know what I like. So, taking a stab at good ole experimenting, put heavy gauge on the lows and lights on the highs on my freshly purchased RTi70's......not even "broken in" yet and I could tell an audible difference (for the better) as soon as I turned the receiver on. About the middle of next week, the PSW-350 should be in, and be an even better compliment to the already great sounding speakers that make up my Heavy Metal soundstage Till then, I guess I will have to keep the bass pussed out on the EQ. (only a little) Thanx for the posts and arguments on bi-wiring. Finally purchased the RTi70's after going back and forth over the Infinity Alfpha 50's or 40's.....Like I say, let your own ears to the deciding and after bringing everything from Pantera to Pink Floyd to the sound room at the store, the Polks delivered what I was looking for. Think I'll get a coupon for the acolades? Yeh, right...when Metallica puts out an album!!!
