New Dynamic Balance Acoustic Array

Whether upgrading your home theater setup with an advanced Atmos configuration or enjoying your favorite music, Dynamic Balance ensures a rich, clean, full-range sound no matter what you’re listening to. This patented technology eliminates issues that reduce speaker performance.

High-Resolution Audio Performance

Our newly designed Terylene dome tweeter delivers clear and detailed high frequency response for realistic reproduction of vocals and instruments. Certified and capable of delivering 40kHz to support the latest high resolution audio files so it feels like your right there in the studio or concert hall

Custom Mid-Range Drivers

Mica-reinforced polypropylene cones with butyl rubber surrounds, four-layer voice coils, massive ceramic motor structures and high-temperature Conex fiber spiders combine to create drivers of exceptionally high efficiency, for clean, clear bass, better linearity, lower distortion and greater durability.

High Sensitivity and Maximum Compatibility

Works with the most modestly-powered amplifier or receiver. Whether you’re connecting them to the newest digital processor, or your vintage rig, you get sound reproduction that’s spacious, clear, enveloping, and realistic. Plus, it’s compatible with latest Dolby and DTS surround sound technologies

Power Port Deep Bass Technology

Power Port® is our patented design that smoothly transitions the air flow from the speaker’s port into your listening area. It also extends the overall bass port, providing greater surface area to eliminate turbulence and distortion, for bigger, more musical, deep bass impact. Plus, it offers 3dB more bass response output than a traditional port.

Quality Crafted Cabinet Design

Strong, rigid and acoustically inert enclosure reduces unwanted internal standing waves for less audible coloration. And non-resonant Meddite MDF construction, with extra bracing and minimum thick baffles, ensures a more lifelike sound

Timbre-Matched

Designed with the same components throughout to achieve seamless speaker-to-speaker blending effects in multi-channel systems.
