Bowers & Wilkins HTM81D4 800 Series Diamond Center Speaker Gloss Black
Product Description
For those who demand the best in home theater sound, the Bowers & Wilkins HTM81D4 stands as a flagship performer. Its Diamond dome tweeter and Continuum cone midrange ensure crystalline highs and transparent, articulate midrange, making it a worthy partner for the 801 D4 and 802 D4. And with twin 200mm Aerofoil bass cones, expect bass that's both deep and controlled.
This 3-way vented-box system is designed to sit at the heart of your home theater, delivering sound that matches the screen's visuals in quality and intensity. The HTM81D4's solid body Tweeter-on-Top design minimizes distortion, while the aluminum bass pods provide a stable foundation for the Aerofoil cones, ensuring that every note is delivered with precision.
Whether you're setting up a dedicated home theater or enhancing a versatile living room, the HTM81D4's 90dB sensitivity and 8Ξ© nominal impedance make it compatible with a wide range of amplifiers. It's more than just a speaker; it's the core of an immersive audio experience.
At MODIA, you can experience the HTM81D4 in our acoustically treated showrooms across Houston, Dallas, and Austin. Schedule a demo to hear this center channel's remarkable integration and detail, and let our experts guide you in crafting the perfect setup for your space.
