Achromatic
W70D Versatile High and Low Boy Deluxe Four-Way Speaker System.
Exclusive
Sand-Filled Enclosure
The
new W70D incorporates the finest components for multiple speaker systems. The
12 ½" woofer employs a
massive (9 ½ lb) magnet assembly
on a heavy cast aluminum chassis. The 2" pole piece and magnet keeper
plates of finest grain-oriented, high permeability Sheffield steel, insure
maximum gap flux density with minimum heat loss, as well as exceptional power
and transient handling ability. Low natural resonance, high but well controlled
compliance, and long axial excursion add to the thrilling bass response
capabilities of this acoustic suspension system.
A special,
heavy duty 8" speaker serves as a "passive" radiator for the
upper bass range and as an energized driver for the lower midrange. An
acoustically isolated 5" unit handles the upper midrange, wwhile
Wharefedale's advance-design mylar pressure-dome tweeter contributes pure,
wide-angle treble. Individual, continuously variable controls adjust the mid
and treble ranges.
The
enclosure employs Wharfedale's exclusive sand-filled construction for maximum
inhibition of cabinet sound coloration. The versatile design permits use of the
W70D as a "high boy" when placed on end, or as a "low boy"
when placed on its side. Superbly styled, the W70D is often used, because of
its table top, as an end table alongside sofas or chairs. Because of its low
height, it is also ideal for positioning under bay windows. The front grille is
removable for decorative changes.
