I have two sets of Polk SDAs. The big daddy SRS 1.2 and a 2.3 and would like to use them in a 5.1 or DTS system. I would need to get an third set od SDA's for the center. Has anyone done this and are there any problems doing this. Would you use the inter connect cable in the front or just use them as separate speakers. I have found that using the polks SDA's as front spreakers only in the 5.1 system doesn't work, they over power everything else. Is this a crazy idea?
