    Default Speaker choosing - RTi8 - timbre matching

    hello and thanks...

    When I designed my basement HT, I installed TC625i's and TC620i's for the in wall rear surround sound, according to the Polk's web these timbre match with the RTi-A's, but I was wondering if the RTi8's will work as well for timbre matching?

    thanks
    chris

    The RTi8's are acoustically identical to the RTi-A5, so yes.

    You should be fine, more important to timbre match the front 3 speakers.

    This is a good question

    I have four RTi8 (Front LR, Rear LR). I'm using an RTi A (CSi A6) for the center.

    I would say that my set up works well for me. (key phase)

    I would also say that to RTi8 and RTi A line of speakers do sound nearly the same.

    During a couple hours of demo at American TV here in St. Louis, I got the chance to sit and listen to the RTi8 and RTi A 5 floor standing speakers which are similar to each other.

    Both pairs have two 6.5 inch drives and 1" silk dome tweeters. They have the same overall Frequency response (30hz-27kHz), same power recommendation, and the same 90 db efficiency rating.

    However, while playing both pairs of speaker thru a Denon AVR, I found the RTi8ís to be brighter in its sound delivery vs the RTi A 5 which sounded a little warmer with all setting being equal on the receiver while playing Apple Lossless music tracks. I didnít notice this as much during movie playback.

    (NOTE) This could be because of American TVís wiring and switching board set up which I would say leaves much to be desired. I have a Journeymanís Electronic Certification from the US Air Force.

    Secondly, while setting up my own system using an RTi A series center channel I felt the same way. This is to say that RTi8 sounded a little brighter in sound production than the RTi A center channel speaker. However, after a period of play and system calibration things lined up really nice.

    I find the mixture pleasant to my ears. Iím not any expert but I do have earsÖ
    I donít think it will matter at all considering your rears are different.

    Thanks everyone for your replies, this was very helpful. Currently I have Infinity IL30s for my fronts so I think I will see a massive improvements by rounding out my HT with Polks; currently debating between the RTi8 & RTi A3s
