Polk Audio Blackstone TL1 Satellite Speaker – Clearance / Open Box

Polk Audio Blackstone TL1 Satellite Speaker Whether you’re looking for your first home theater sub/sat system or want to upgrade to more performance, you’re in for a big surprise in a small, compact package from Polk Audio. The predecessor to Blackstone® TL, our RM series, was always about “Big Speaker Sound Without The Big Speaker.” Blackstone TL represents a significant leap forward, delivering an astonishing home theater performance never before heard in compact loudspeakers. Time Lens Technology The acoustic centers of the tweeter and mid-bass driver are located in the same plane for superior imaging, while the acoustic lens incorporated in the grille  moothes the tweeter’s frequency response. The TL Series creates imaging and frequency balance previously impossible in small, high performance satellite speakers. TL1 Satellite Aperiodic Tuned Rear Port enables better blending with a subwoofer. This design combines the bass extension of an acoustic suspension enclosure with the mid-bass boostof a ported enclosure by controlling air flow through the port for better extension without distortion. Curved Enclosure Design employs non-parallel surfaces that not only lead to a stronger, more rigid and acoustically inert enclosure, but they also result in less audible coloration from internal surface resonances. 1/2″ Silk Dome Tweeters for crisp, clear imaging and smooth response that’s never tiring.
