Diamond 155

2.5-way floorstanding speaker, 16.5cm woofer and midrange, 25-150W power handling, 89dB/W/m sensitivity

Product information

The Wharfedale Diamond 155 is the newest floorstanding version of the popular Diamond series - designed to improve and replace the popular Diamond 10.3. The Wharfedale Diamond 155 looks majestic, thanks to the design overhaul and new cabinet design and are available in four wood finishes. 

These speakers offer a very competitive 89dB/W/m sensitivity, making them an ideal partner for a wide range of amplification. These speakers are designed to fit in with the rest of the Diamond range (including older models) both in terms of sound and looks. 

The Diamond 155 is the perfect choice for many systems - offering a larger soundstage and better bass response than its bookshelf counterparts in the new Diamond range. Equally at home in an AV setup as with hi-fi applications, the Diamond 155 is very reasonably priced - offering exceptional performance without stressing your pocket!

Design Improvements 

The new Kevlar-cone units mean the mid and bass response is greatly improved featuring some technologies used in the Jade series. Built in to the low frequency and midrange cones are semi-elliptical ‘break-up’ areas which have the effect of evening out the response across the audible range.

Also featured is a new bass-reflex port - offering technologies usually reserved for much higher-end products. This allows a nice, clean transition between the pressure variation in the cabinet and the low frequency sound developed in the room.

The cabinet shape adds to the impressive sound; constructed to rectilinear shapes, the internal volume is maximised whilst the bass response delivers an impact at an optimal depth. The new composite multigrain material used to construct the cabinets results in a sturdy design with minimal cabinet colouration and minimal internal sound leakage.
