At $100 ea, the Polk Monitor60s are a very good deal. I don't think they have been that low in price for awhile. The Polk Monitors are equivalent to the Polk TSi series that Best Buy sells. They are just different cosmetically. Real bargain buying from Newegg.
Do you do a lot of gaming? Do you like action movies? I'm biased toward good subs for their bass extension, SQ, and output. Adds realism when the explosion feels like an explosion, not just a rumble throughout your room. The BIC F12 is very much a budget HT sub. You would get much better bass out of higher class of sub and improve the HT and gaming experience. Something like the HSU VFT-2 MK4
. You would also benefit from the more powerful sub given that your living room is part of a larger open floor plan.
For receivers, one of the features to look at is room correction software. Audyssey MultiEQ or better (not 2EQ) on Denon and Onkyo, and the version of Yamaha's YPAO that is listed as "multi point" on their specs. Those versions EQ the speakers and the sub. Other room correction software only EQs the speakers, and subs can use a lot of help in a room. Here's an overview of MultiEQ
. Good room correction software really does improve the SQ of your entire setup. You will definitely appreciate the difference.
Otherwise, pick the receiver that has features that interests you. There's minimal gains in worrying about the wattage between versions (doesn't impact output as much as people assume). Do you want to play the music from your computer? iPhone/iPad? Android phone? For example, there are different networking and connections features for music streaming that are nice.
