Our Take
Midrange Driver
The D320 speakers incorporate an advanced midrange/bass drive unit, using the latest generation of Wharfedale’s woven Kevlar cones, bonded to a lightweight high tech foamed polyether surround. The driver delivers clarity and dynamic musical expression, for a detailed performance from a low-cost speaker. The cone is driven by a super long throw voice coil motor system, for increased bass extension, with low frequency accuracy. The magnetic flux is controlled by a specially shaped pole plate that reduces inductance, ensuring distortion of bass frequencies remains at a minimum, while oversized ceramic magnets create high sensitivity and smooth response across the cone.
WFR Tweeter
The Wide Frequency Response tweeter was original developed in the Diamond 11 Series, and has been fine tuned for the D300 Series. The 25mm textile dome tweeter is built in its own cabinet, with fibre filling for damping. The tweeter is driven by an oversized ceramic magnet with a copper capped pole piece for flux control, and performs with a smooth and pure tone, producing defined high frequency detail.

Crossover and Cabinet
Wharfedale’s Advanced Software and Listening Iteration system has been used to carefully develop the new crossover to add emphasis on lifelike reproduction of voices and instruments. The crossover components use low loss polypropylene capacitors and laminated core inductors for the optimum signal transfer. The cabinets for the D320 speakers feature 28mm front baffles, profiled to reduce diffraction edge reflections from high frequencies. Inside the cabinet, critical bracing is employed on the panels to eradicate unwanted noise and the walls are lined with a specially developed fibre to absorb resonant sounds. The sound output by the speaker therefore remains free from external noise and colourations, to produce pure and delicate audio.
P-EQ Bass Reflex Port
The D320 speakers included the newly developed P-EQ Pressure Equalisation bass reflex port for deep and controlled bass. The bass frequencies are emitted through a downward firing port in the speaker base, sounding Omni-directionally into the room. This reduces the pressure differential between the high pressure port and the low pressure room, minimising turbulence and chuffing, whilst improving bass response and efficiency. The P-EQ bass port on the D320 creates the fundamental notes of bass instruments, to match the realism of the midrange and tweeter. With the down-firing port, the D320 speakers can also be placed closer to the wall than conventional speakers without affecting the bass response, making the speakers less obtrusive in a room, and more easily placed on shelves.
The D320 speakers offer a remarkable performance from a budget, compact speaker, with an impressive midrange and fluid high end detail, with an accurate and controlled bass from the P-EQ port. The D320s are available in Black, White, Walnut and Rosewood finishes.
