Hey folks, First off I should list all of my speaker equipment to give you an idea of my setup. Center: Acoustic Research Performance Series 2 5.25 Mids 1 1" Poly Dome Tweet Front Stage L/R: Acoustic Research Hi Res Series AR9 Towers 2 5.25 Mag-Alloy Mids 1 1" Titanium Dome Tweet 1 10" Sub per cabinent Surround L/R: Acoustic Research Performance Series 216 BookShelf 1 6.5" woofer 1 1" Poly Dome Tweet My dilemma is that my Center Channel does not exude the same tonal charecteristics of my Hi-Res Towers and I should have known from the get go that if I was going to buy the best Front Stage Towers that AR has, then I also should have went with the timbre matched Center Channel. My problem is 2 Fold. Problem #1 is that I feel the center channel does not produce enough low end frequency. What kind of lows should I expect from any Center Channel? 70 Hz? The second problem is that the Poly Tweet will never sound the same as a Titanium Tweet. For my Surrounds the poly works fine but where tonal matching is critical the poly doesn't match the metal.. I E-Mailed AR and asked if I could buy the Hi-Res 5.25" Mids and the 1" Titanium Tweet and they responded yes I can and the price each for the Mag-Alloy mids are $49.00 each and the Titanium tweeter is priced at $76.00 Now I could just buy the cheaper of the 2 AR Hi-Res Centers the AR2C which has 2 5.25's and the 1" encased in a polymer enclosure for $179.00 ish... Or I could buy the AR4C which adds 2 downfiring 6.5" sub's for just under $300.00. The problem with the 4C is that those down firing subs will no doubt make my RPTV's lenses shake when bass his.. So I was thinking I could buy the Hi-Res components (Mids, Tweet, Crossover from the AR9's, AR9 Binding Posts. And then I could Bi-wire the center or I could just buy the mids and Tweet and forget Bi-Wiring... What is your opinion on this? What should I expect from a Center Channel? Thanks in advance!
