experience to the next level. With a lifelike sound that envelops you from all angles, you'll feel like you're
right in the middle of the action, experiencing every thrill and every emotion in effortless but stunning detail.
Wharfedale's commitment to home theatre design has been consistent for many years and product series.
It is clear to see the DIAMOND 12 series' success in this category. Now, with the DIAMOND IW and DIAMOND
OW models, the emphasis is on hearing rather than seeing, allowing for a truly immersive audio experience.
The latest in-wall and on-wall options have been designed with a focus on the celebrated DIAMOND 12
principles. These options are equipped with the innovative Klarity™ cone material, which is a blend of
Polypropylene and mica. This unique blend adds stiffness to the cones, reducing any flexing. As a result, the
cones are incredibly lightweight, rigid and have lightning-fast response times. The result is a loudspeaker
with low colouration that will impress even the most discerning audiophile - a basis that easily translates to
the world of home cinema.
The Klarity™ cone material is made from a unique blend of Polypropylene and mica, which gives it the ability
to reduce flexing and add stiffness. This results in a cone that is lightweight, rigid, and has lightning-fast
response times. The low-damping surround on the cone achieves both low colouration and expressive
dynamics. To achieve a flat response curve without resorting to a high-damping surround; ribs were added
for further stiffening. The magnet system is also precision-made with an aluminium compensation ring to
minimise the effect of variations in inductance. The end product strikes the perfect balance of dynamics and
impact, with detail and depth of projection.
The 25mm dome of the DIAMOND 12 maintains its natural sparkle
with the use of a woven polyester film and high-loss coating that
delivers open and smoothly extended high frequencies. The magnet
system and front plate have been optimised for wide dispersion and
uncompressed behaviour. The front plate is flat, exposing the dome
as much as possible, and a short duct on the front plate balances
the acoustic load while improving the SPL (Sound Pressure
Moving further into the world of AV and home cinema, the DIAMOND
IW and OW crossovers were created initially through extensive
computer modelling, focusing on enhancing nuances that are
important for a home theatre experience. Elements such as vocal
clarity and heightened transients were given priority to create a
cinematic experience for this dedicated integrated HTS solution. As
with all Wharfedale models, numerous listening tests were
conducted to ensure that the end product was in line with the original
concept - an exhilarating home theatre experience that enhances
entertainment while watching movies, playing games, and listening
The DIAMOND IW models come in two forms - IW-1 with a 165mm
(6.5") mid-bass driver and 25mm (1") soft-dome HF, or IW-2 with dual
165mm (6.5") mid-bass drivers and the same 1" soft-dome HF. The
precision-machined baffle is expertly designed to offer a sturdy
foundation for high-performance applications.
Meanwhile, the DIAMOND OW series boasts an ultra-slim profile of
just 141mm deep, making it an excellent choice for unobtrusive
The cabinets are incredibly sturdy and well-constructed, with
specially crafted bracing that adds strength and stability. Its design
minimises any unwanted vibrations, ensuring a pure, resonant sound
for enhanced depth and impact.
Both IW and OW models come with easy-mounting templates and
accessories for a stable and secure installation.
