Bowers & Wilkins HTM81 D4 Centre-Channel Speaker Review: Elevating Home Theatre Audio to New Heights

In this Bowers & Wilkins HTM81 D4 Centre-Channel Speaker review, we delve into the pinnacle of home theatre audio technology. As the largest centre-channel speaker in the renowned 800 Series Diamond, the HTM81 D4 is designed to perfectly complement the 801 D4 and 802 D4 models, delivering unparalleled audio quality and cinematic immersion. Our team at The Audio Tailor has been thoroughly impressed by this powerhouse speaker, and we're excited to share our insights with you.

Uncompromising Design and Technology

The HTM81 D4 is a testament to Bowers & Wilkins' commitment to audio excellence. This 3-way vented-box system boasts an array of cutting-edge technologies that set it apart in the world of high-end audio.

Diamond Dome Tweeter: A Crowning Achievement

At the heart of the HTM81 D4's high-frequency performance lies the Diamond Dome tweeter. This marvel of audio engineering, introduced over 15 years ago, remains unrivalled in its ability to deliver ultra-stiff, supremely accurate sound reproduction. The tweeter's low mass and exceptional stiffness contribute to a level of detail and clarity that must be heard to be believed.

Aerofoil™ Bass Cones: Precision-Engineered Low-End Performance

The HTM81 D4 features twin 200mm (8-in) Aerofoil™ bass cones, a technology that combines low mass with high stiffness. The carbon-fibre skin and variable-profile foam core work in harmony to reduce distortion and deliver cleaner, more accurate bass. The addition of the Anti-Resonance Plug further enhances low-frequency performance, ensuring that every cinematic explosion and musical note is reproduced with stunning clarity and impact.

Continuum™ Cone FST Midrange: The Heart of Vocal Clarity

The 150mm (6-in) Continuum™ cone FST midrange driver is a crucial component in the HTM81 D4's ability to reproduce dialogue and vocals with exceptional clarity. This decoupled unit ensures that the midrange frequencies are delivered with precision, free from cabinet vibrations that could colour the sound.

Exceptional Build Quality and Aesthetics

The HTM81 D4's build quality is nothing short of exemplary. The curved cabinet design not only looks stunning but also serves to reduce internal standing waves, contributing to cleaner sound reproduction. The twin solid aluminium bass pods, each clamped into an aluminium plate, provide the ideal mechanical support for the powerful bass cones.

Available in a range of finishes, including the striking Satin White pictured, the HTM81 D4 is as much a visual statement as it is an audio powerhouse. Its elegant design ensures it will complement even the most stylish home theatre setups.

Performance That Demands Attention

In our listening tests, the HTM81 D4 consistently impressed with its ability to anchor complex soundstages and deliver dialogue with exceptional clarity. The speaker's frequency response of 28Hz to 28kHz (+/-3dB from reference axis) ensures that it can handle everything from the deepest bass notes to the most delicate high-frequency details.

The speaker's 90dB sensitivity (on axis at 2.83Vrms at 1m) means it can fill even large rooms with ease, while its nominal 8Ω impedance (minimum 3.1Ω) makes it a suitable partner for a wide range of high-quality amplifiers.
