Wisdom Readies Behind-Screen Planar Speakers

CEDIA Expo 2009 Atlanta
– Wisdom Audio plans to launch two Sage-series line-source planar-magnetic
in-wall speakers whose 50-inch heights were designed for installation behind
increasingly popular 2.35:1 aspect-ratio projection screens.

A suitcase-shaped
subwoofer is also new.

“There was demand for models
incorporating our line-source technology that could physically fit behind the
increasingly popular 2.35:1 aspect ratio screens without protruding above or
below,” said president Mark Glazier. The company’s other in-wall line-source
models are 75 inches tall.

Like other Sage-series
speakers, the new models feature Audyssey MultEQ XT room-correction technology
embedded in their active two-way crossovers to alter speaker response to
compensate for distortion that might be caused when a perforated screen is in

Pricing and
availability were unavailable at press time.

The L100i and
C150i use planar-magnetic line-source technology to reproduce mid and high
frequencies. The L100i uses one eight-woofer array at one side of the speaker
to reproduce bass frequencies, and the C150i uses an eight-woofer array on both
sides. Both are designed for vertical installation. They are meant to be used
with biamplifying SC-1 electronic crossover and, to drive the woofers, an
outboard SC-1 amplifier.

The Sage series
consists of more than 20 in-wall, on-wall and in-room speakers from 20 to 76
inches tall.

Also new is a
$4,000-suggested in-room powered sub whose suitcase shape allows for placement
options unavailable from box-shaped subs. The 37- by 22- by 6-inch sub, a smaller
powered version of the Sage-series S90i in-wall subwoofer, is designed for
rooms in which an in-wall sub isn’t feasible. It fits under or behind
furniture. Also contributing to placement flexibility is the subwoofer’s
configurable enclosure, which allows installers or consumers to select one of
three sides on which the bass port will vent.

The sub features
dual 5×7-inch woofers, a 300-watt internal amp, and SPLs exceeding 120dB at 22
Hz. It ships in the fourth quarter.
