NEW DYNAMIC BALANCE DESIGNED ACOUSTIC ARRAY.
Whether upgrading your home theater setup with an advanced Atmos configuration or enjoying music, Dynamic Balance ensures a rich, clean, full-range sound no matter what you’re listening to. This patented technology analyzes the speaker’s entire electro-acoustic and mechanical system for improved material selection and more efficient geometry.
HIGH-RESOLUTION AUDIO PERFORMANCE.Our newly designed Terylene dome tweeter features curvilinear formers that extend response and lower resonance. Its powerful ceramic motor structure also lowers system resonance and extend low frequency response for better dispersion in the critical midrange, delivering 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 you’re right there in the studio or concert hall.
CUSTOM MID-RANGE DRIVERS.Mica-reinforced polypropylene cones with butyl rubber surrounds, 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.
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.
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.
