While painting my living room, I noticed that one of my surround grills was loose. Reseating it released a fair amount of disintegrated foam driver surround. So, it's time for new surrounds and I might as well upgrade the center at the same time.
Because I'm using Polk SDA-1C's with their updated tweeters (and likely a x-over rebuild soon) as the front mains, I want to stay with their products to attempt timbre-matched drivers. Support recommends a CSiA4/CS10/CS20 for the center and RM8/TL1/TL2 for the satellites.
I'm currently using the 2600 in 5.1 mode. What's the consensus on the best combination of speaker channels for home theatre with this receiver? Is it more effective to add 2 front presence speakers or have a pair each for surround and surround back speakers? Can I correctly use one of these settings for side speakers? Which scenario takes advantage of the most released material?
Or should I just stick with 5.1 due to lack of material and/or cost? Since my room is only about 13' deep, even if I could make the side speakers work, would it be worthwhile?
