Hi, newbie here who knows absolutely nothing about audio and video but very willing to learn. I just sold an my Polk S-6's and looking to upgrade. I don't have tons of cash to drop on speakers so my ceiling is around $400/pair. Any help steering me in the right direction would be appreciated. FYI - I'm not an audio buff and my speakers would be mainly used for movies.... I have the following components Receiver - Yamaha RX-V371 Sub - Poll Audio PSW 505 12" Center - Infinity Systems Thanks!
