Polk RT55i speakers

These bookshelf monitors sold for $600 per pair when new. These are a steal at $140. No lowball offers. Polk's latest bookshelf speakers sound better than ever, thanks to design concepts inherited from Polk's impressive RT towers and a few subtle technology upgrades. They feature Power Port technology for amazingly clean, powerful bass. And their drivers are mounted on a raised bezel to eliminate unwanted grille diffractions — these gems really image! The 2-way RT55i produces sweet, silky-smooth highs, employing Polk's acclaimed 1" trilaminate dome tweeter (now fine-tuned for more precision!). Two 6-1/2" Dynamic Balance® drivers team with Polk's Acoustic Resonance Control (ARC) system (dual complementary ports tuned to different frequencies) to minimize cabinet resonance and deliver naturally smooth, clean midrange, as well as deep, accurate bass. Two sets of gold-plated binding post connectors let you biwire or biamplify the RT55i for even cleaner sound and improved imaging. Finished in real black oak wood veneer.
