Vanguard Dynamics - CSC-601STT - Dual-Voice 6.5" In-Ceiling Speaker

Vanguard Dynamics - CSC-601STT - Dual-Voice 6.5" In-Ceiling Speaker

STTTM Stereo Tweeter Technology:

A world first! Vanguard Dynamics is the only speaker company to utilize this technology. Normal stereo in one speaker technologies uses two tweeters placed close together to deliver the left and right signals from the source. This configuration causes compression and distortion in the music as waves from each tweeter interact with the other. Stereo Tweeter Technology utilizes a carefully designed dual voice coil tweeter that assures better acoustic delivery and low distortion thereby providing a more musical experience.

This In-Celing speaker also utilizes a unique design which eliminates phase cancellation, including a 6.5" Polypropylene Woofer and STT 1" Soft Dome Pivoting Tweeter. Vanguard's goal was to create the finest architectural speakers available. How is such a lofty goal achieved? It starts with a management team that has been designing products for the architectural audio market for over 20 years. The team’s experience and engineering expertise is then combined with passion to create speakers that stand apart from the ordinary. To us, great speakers create great music.

Because their team is genuinely excited about music and still gets a thrill when they listen to their favorite music perfected on one of its newest creations. Of course each of their speakers is backed by a LIMITED LIFETIME WARRANTY.
