2-Way Driver Design: The Wharfedale Diamond 220 is a 2-way bookshelf
loudspeaker which incorporates a 1" fabric soft-dome tweeter and 5" woven kevlar
cone woofer. A finely tuned crossover guarantees a smooth transition between the
tweeter and woofer with an enjoyable audible experience, both on and off-axis.
- 1" Tweeter: The 1" tweeter uses a sheer fabric dome and advanced
ferrite magnet system, surrounded by a carefully crafted wave guide that
encourages outstanding midrange performance too.
- 5" Woofer: Semi-elliptical "break-up" areas on the
woven-kevlar woofer smooth the response through the audible range. The cone
edges are treated with a unique diamond pattern rubber surround.
Non-Resonant Cabinet: The speaker cabinet combines layers of particle
board and MDF, bonded in a unique structure to damp annoying resonances and
block internal sound leakage. The result is that the "noise" and distortion from
cabinet walls are buried more than 35dB below the driver output. Cabinet walls
and internal bracing were developed using Wharfedale's latest "Virtual Speaker"
software, with the help of Delayed Cumulative Spectral Analysis. The top,
bottom, and side walls of the cabinets are finished with a wood veneer (black,
rosewood, or walnut), while the baffle is finished with a gloss black lacquer.
Bass Port: Exiting the base of the speaker cabinet is a slot
loaded distributed port created by the plinth. This equalizes the air pressure
to mimic that inside the cabinet allowing a smooth transition between the
pressure variation in the cabinet and the low frequency sound developed in the
Dual Binding Posts: Each bookshelf loudspeaker has two sets
of binding posts connected by jumper-plates. The binding posts will accept bare
wire (up to 10AWG), pin connectors, spade connectors, & banana plugs (single
only). Using these dual binding posts, you can bi-amp or bi-wire the speakers.
Bi-wiring or bi-amping the speakers provide improved bass & treble performance.
If you decide to bi-wire or bi-amp, you must remove the jumpers between the
terminal posts (failure to do this could result in damage to your amplifier and
- Bi-Wiring: Bi-wiring can provide noticeable
improvements in the overall transparency of your loudspeakers. Run separate
speaker wires to the low & high frequency drivers from a single amplifier
(the upper set of binding posts are for the high frequency drivers; the
lower set of binding posts are for the low frequency drivers).
- Bi-Amping: Bi-amping allows you to use separate
amplifiers for the high & low frequency sections of your loudspeaker for
greater dynamic range & lower distortion. We recommend that your separate
amplifiers have identical gain to preserve the speaker's voicing balance.
Mounting Options: These bookshelf loudspeakers can simply be
mounted on stands, shelves, or other piece of AV furniture with a flat surface.
Eight self-adhesive rubber feet (4 for each speaker) are included to protect the
bottom of the speaker and the mounting surface, while isolating the speaker
cabinets from the mounting surface. The rubber feet add approximately 0.375" to
the overall height of the speakers.
Note: The speakers do not include any type of wall-mount bracket, keyhole slot,
or threaded insert.
Placement: Try to position the loudspeakers equidistant (6.5' to 13')
from one another and the main listening position. The speakers should ideally be
positioned so that the tweeters are roughly at ear level to a seated listener.
The speakers should be "toed" or angled (15°
to 40°) into the main listening position.
The speakers can be positioned as close as 2.3125' to 3.3' from a side facing
wall. There should be a distance of at least 0.6875' to 3.3' between the back of
the speaker cabinets and the wall (the speakers' bass extension will improve if
they are positioned closer to a wall or corner).
Diamond Series: The Wharfedale Diamond series consists of
three floor-standing loudspeakers (Diamond
Diamond 240 /
Diamond 250), three bookshelf loudspeakers (Diamond
Diamond 220 /
Diamond 225), and two center-channel speakers (Diamond
Diamond 240C) - all sold separately.
