Premium Materials for Optimized Audio

DT Series speakers use exclusive composite-filled polypropylene driver cones with rubber surrounds for superior transparency and longevity.

Annealed Aluminum

Great transients and smooth response are the direct result of the perfect rigidity and lightness of an acoustically optimized annealed aluminum tweeter dome.

High Definition Crossover

Crossover is crucial to high-end audio quality. The high definition crossover network in DT Series speakers is how each one delivers the purest high frequencies.

Designed for Superior Sound

Speakers that visually dominate the room distract from the sound. DT Series speakers have whisker-thin micro-perf grilles with slim bezels that can be custom painted to blend in.
