I am the original owner. These speakers may be used as
either a directional (forward-firing monopole) full range speaker system in a
discrete 5.1 to 7.1 digital system, or as a dipolar ambience generator for use
with either THX or Dolby sources. The surrounds are in excellent shape and work perfectly. Rated 8 only because of age. Buy with confidence - check my perfect feedback. I do not have the original box but rest assured the speakers will be packed safely - double boxed and plenty of foam. I will wrap the speakers in shrink wrap.
System Type: Multiple application surround speaker
suitable for either monopolar or dipolar use. A side mounted button is provided
to select between the two radiation patterns.
Mounting Applications: The unit was designed for
wall mounting. Alternately, the unit may be placed on stands or mounted on the
ceiling, facing downwards.
Surround Applications: Suitable for use with Dolby
Pro Logic, Pro Logic II, Dolby Digital (AC3), DTS, DTS EX, and all future
formats for multi-channel movies or music recordings.
Monopole Pattern: All drivers will radiate in
phase, with a wave launch facing 90 degrees from perpendicular; the dispersion
pattern is 180-degrees with a highly focused image. Some experts claim that
this radiation pattern is best suited for musical recordings and/or DTS
Dipole Pattern: A "null" created by an
out-of-phase driver wiring technique enables the speaker cabinet to disappear
as the source of the sound. An equalization circuit is provided to allow deep
bass to be reproduced with the out-of-phase woofer wiring. Many experts claim
this radiation pattern is best for movies, no matter what type of encoding was
used, as the speakers mimic the "infinite surround" design found in
Dispersion Angle: 180-degree dispersion with either
monopole or dipole setting, enabling even large rooms to be filled with ambient
Woofers: Two-5.5" bass-mids per speaker,
using mica-impregnated cellulose cones to reduce flexing and distortion for
maximum bass impact and highest level of transparency in the midrange.
Tweeters: Two-1" tweeters per speaker, using
fabric domes laminated with two layers of synthetic vinyl for strength and
Ferrofluid liquid cooling for high power safety. Both drivers use our Low
Distortion Motor to enable high volume levels to be reproduced without
harshness or glare.
Crossover: Our proprietary Global Axis
Differential Network enables either in-phase (monopole) or out-of-phase (dipole
null) radiation patterns. Crossover point is 2.2 kHz. High quality air core
inductors and polypropylene film capacitors are used to ensure very high
