Highlights & Key Technologies

Diamond Dome Tweeter & Solid Body Tweeter-on-Top
The HTM81 D5 carries a 25mm (1in) Diamond dome high-frequency unit, decoupled from the cabinet in the Solid Body Tweeter-on-Top. The tweeter housing features the new metal grille mesh design first debuted on the 800 D4 Signature, which significantly improves acoustic performance. A new trim ring design improves perceived quality by moving the sight lines to the side of the pod.

Continuum Cone FST Midrange
Midrange is handled by a 150mm (6in) Continuum cone FST unit fitted with an Anti-Resonance plug and Biomimetic Suspension. The new mid and bass cloth grille design adopts a subtler aesthetic with lighter weight for easier handling.

Aerofoil Bass Cones & Flowport
Low frequencies are produced by two 200mm (8in) Aerofoil bass cones loaded by Flowport in a three-way vented-box system.

Matrix Cabinet
The drive units are mounted in a stiff, curved Matrix-braced cabinet. A refined top plate with smaller, more subtle edges derives its improved acoustic performance from the 800 D4 Signature.
