    Never had a set of these but did you run a cable to the LFE input from the sub out on your AVR?

    You have to run a cable to the lfe input on your 25's in order for the sub to work, that is why you are not getting anything from them.

    Coming in late to this - so keep that in mind....

    1. - do you have the jumpers between the terminals on the back of the speaker? If no - you won't get any bass with just speaker hook ups. If yes, don't connect an RCA cable to any input.

    2. - If you are using the subwoofer output on your AVR (or pre/pro) you want to use the LFE inputs on the speaker. (this will bypass the crossover in the speaker)

    I personally like option 1 (especially if you have other subs in the mix) but thats just me. If you do choose option one - in the AVR - set your front speakers to "large" and sub to "off" (if you do not have other subs in the mix)

    If you choose to use option 2 - make sure speaker is set to "small" with sub to "on".
    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)
