In a predicament, warranty vs great deal. I have found a SPL120 subwoofer for sale for $300 locally. He has all packaging, but apparently damage occurred during shipping (has two corner dings) and he used for two weeks while waiting for his new one. The other option is getting a brand new R-12SW from Costco locally for $250 and it will have full warranty along with costco match. I've heard mixed reviews on the reliability of klipsch subwoofer amps and am curious if anyone else has had issues with them. Is it worth the difference in performance to roll the dice on this sub from offerup? Thanks,
