I'm in the process of building my first real home theater system, and have pretty much settled on the Infinity Primus P163, which from what I've read are a great value at $85. After two of those, a receiver (Onkyo HT-RC360 for $250), and a sub (Bic F12 for $183), my budget is down to around $200 for the rest of the system.
I had been thinking of getting the PC-350 center with that $200, and either leaving the system at 3.1 or using my old Logitech Z-5450 for the surround, depending on which sounded better in testing. However, reading back through the last couple of pages of this thread, I see recommendations for just using a third P163 for the center, which I hadn't considered before. Doing that would free up enough to get a couple of P143s for matching surround and come in right at my budget target of $800.
Is that sort of setup still recommended? Has anyone tried it in the real world? How much would I really be giving up going from the 350 to an additional 163, and would the higher-quality surrounds make up for it? This is for an even mix of movies and gaming with only occasional music, so having dialogue be clear is pretty important.
