approach, precisely targeting key areas to improve in order to make an already great loudspeaker range
deliver even better value for money.
Enhancements across the range include:
New cabinet construction
– a sandwich of particleboard between MDF, which has enabled
improvements both aesthetic and sonic.
New lacquered baffle design further enhances aesthetic qualities.
Improved bass motor system with larger magnets makes the speakers easier to drive and boosts
transient acoustic power.
Enhanced 'Slot-Loaded Distributed Port'
– improved airflow control lowers turbulence and hence
reduces low-frequency distortion.
Upgraded crossover networks further improve the integration between the drive units.
The Wharfedale Diamond 200 Series in full
First to arrive from the new Diamond 200 Series is the
Diamond 220
. Available from October, this pivotal
model is the latest evolution
of Wharfedale’s classic Diamond standmount speaker – a neatly proportioned
design with a 130mm mid/bass driver. It is the direct replacement for the best-selling Diamond 121 from the
outgoing Diamond 100 Series, benefitting from all the enhancements described above, yet Wharfedale has
managed to shave £30 off the RRP
– the Diamond 220 will sell for just £199.95 per pair.
The remaining Diamond 200 Series models will follow in December. These include the
Diamond 210
, an
ultra-compact speaker for rear/surround duties or stereo applications where space is at a premium (£149.95
per pair), plus three floorstanders
– the
Diamond 230
(£499.95 per pair),
Diamond 240
(£699.95 per pair)
and
Diamond 250
(£999.95 per pair).
The
Diamond 220C
home cinema centre speaker (£199.95) completes the range. Anyone wishing to
compile a 5.1 or 7.1 surround sound package from the Diamond 200 Series can add an active subwoofer
from Wharfedale’s highly rated PowerCube SPC range, selecting an appropriate model to suit their room.

Many of the speakers’ core features are unchanged from the Diamond 100 Series. The bass and midrange
cones are fashioned from woven Kevlar and incorporate semi-
elliptical ‘break-up’ areas – visible as raised ‘V’
shapes on the cone
’s surface – that smooth the response throughout the audible range. The dust cap is
blended and treated to provide a smooth transition with the treble unit, which incorporates an advanced
ferrite magnet system and a carefully constructed waveguide around the fabric dome for optimal dispersion.
Bass performance is enhanced by a newly refined version of the Slot-Loaded Distributed Port, first
introduced in the outgoing Diamond 100 Series. Instead of the usual circular reflex port, all Diamond 200
Series models incorporate a port that exits at the base of the speaker cabinet, loaded by a slot that is
created by the plinth. This equalises the air pressure to mimic that inside the cabinet, allowing smooth
transition between the pressure variation in the cabinet and the low frequency sound developed in the room.
