    Default LSI hookup

    Hi guys,

    I am a newbie. I apologise for the "basic" questions.
    This is my situation.

    Got three zones:

    living room - 2 x Polk Audio LSI 25
    living room - 4 x Polk Audio LSI FX
    living room - 1 x Polk Audio LSI C
    living room - Yamaha RXV 1900

    Outside Patio - 2 x Polk Audio Atriums

    Bedroom - 2 x FOCAL in ceiling

    Home is already prewired. And I have already mounted the speakers.
    How best to hook up to the Yamaha?

    I am especially concerned about the living room - a bit of overkill...with the 2 floor with powered subwoofers and 4 surround speakers ...8.1 system :) ?

    Any help/advice would be greatly appreciated.

    Welcome to Club Polk.

    Living room would be considered a 7.3 system depending on how you have things hooked up.

    I would run your living room from an external amp and use the amps in the AVR for your other speakers.

    Do you have a separagte subwoofer (other that the built in subs in the 25's) in your living room? If so - what kind?
    Mains.............Polk LSi15 (Cherry)
    Center............Polk LSiC (Crossover upgraded)
    Surrounds.......Polk LSi7 (Gloss Black - wood sides removed and crossovers upgraded)
    Subwoofers.....SVS 25-31 CS+ and PC+ (both 20hz tune)
    Pre\Pro...........NAD T163 (Modded with LM4562 opamps)
    Amplifier.........Cinepro 3k6 (6-channel, 500wpc@4ohms)

    Thanks for your input McLoki.... I want to use the tri-zone capability of the Yamaha to run the 3 rooms.
    My big concern is the living room.
    For the living room I have only got the built in subs in the 25's. How do I connect those 2 powered sub woofers to the single sub output of the yamaha? And how do I ensure that the subs are not out of phase cancelling each other?
    Any help will be appreciated!

    use a y connect on the back of the yami . with this you can now run both subs. if the speakers are a matched pair I would assume that they are already set up to provide proper phasing of the bass modules...
