About the CSi5
The CSi5 is a discontinued, two-way center-channel loudspeaker designed to match Polk Audio’s RTi-series speakers. It uses two 6.5-inch Dynamic Balance polymer-composite mid/woofers and a 1-inch silk/polymer-composite dome tweeter. Its vented enclosure combines a rear Power Port with a front Acoustic Resonance Control (ARC) port. The cabinet is magnetically shielded and finished in real-wood veneer; dual gold-plated five-way binding posts support bi-wiring or bi-amplification, and an adjustable kickstand helps with placement on shallow television surfaces.
