SoundTube PC-SURR-II 3-Way Switchable Surround Speaker

The PhaseTech PC-SURR-II is a low-profile, on-wall surround speaker offering switchable bipole/dipole modes for customizable home-theater immersion. Its sealed enclosure houses a patented 6.5″ tri-laminate Kevlar/RPF®/glass-fiber flat-piston woofer, two 4″ polypropylene midranges, and two 1″ soft-dome tweeters to deliver enveloping, articulate surround effects from 60 Hz to 22 kHz.

Just 5.25″ deep, the PC-SURR-II mounts flush to walls or speakers stands, blending seamlessly into any room. Gold-plated binding posts and a removable magnetic cloth grille ensure both reliable connections and a clean aesthetic.
