Advanced Five-Driver Array
Four 5.25" BDSS midrange woofers and a 1" aluminum oxide tweeter deliver ultra-clear vocals with uncanny realism.
Built-In 8" Powered Subwoofer
An integrated 8" powered subwoofer delivers clean, detailed bass that perfectly blends with mids and highs, anchoring voices and effects with rich, full-range sound.
3XR Architecture with Dual Bass Radiators
3XR™ Architecture—introduced in our flagship Descend Series—combines a subwoofer and two passive radiators to produce huge, impactful bass that’s unrivaled in a center channel speaker.
BDSS System and Linear Response Waveguide
Midrange woofers feature Definitive’s Balanced Double Surround System™ (BDSS), which improves excursion and provides superior midrange detail. Our patented Linear Response Waveguide™ extends off-axis dispersion for total sonic immersion.
Patented Intelligent Bass Control
Sophisticated digital processing seamlessly blends subwoofer output with mids and highs to provide powerful deep-bass performance without impacting midrange clarity.
Consistent sound across other Definitive Technology series gives you the flexibility to mix and match Dymension™, Dymension CI, and Mythos speakers to design your dream home theater and whole home system.
