Polk has redesigned their best-selling RTi series speakers for even better audio performance. The RTi4 bookshelf speaker dishes out surprisingly rich, full sound for such a compact model. It takes advantage of the latest generation of Polk's Dynamic Balance® drivers — the 5-1/4" woofer and re-worked 1" silk/polymer tweeter provide smoother response and better detail than the RTis of the past. And these speakers don't just sound great; with its real wood veneer in your choice of black oak or cherry finish, they look great, too.
As always, Polk has paid close attention to the details. The RTi4's cabinet features all-MDF construction with extensive internal bracings that virtually eliminate sound-muddying resonance. It also includes Polk's exclusive Power Port technology for clear, deep lows, and an ARC (Acoustic Resonance Control) port for more natural mids. Dual gold-plated 5-way binding posts allow for bi-amping or bi-wiring.
The RTi4s do a great job with stereo music on their own, or you can team them with a powered sub for rib-rattling results. For dynamic, detailed movie sound, use 2 pairs as your home theater's front and surround speakers. For larger rooms, the RTi4s work perfectly as surrounds in combination with RTi tower front speakers.
