S-150 Surround Speaker System
ince the surround speakers are vital to the
S
recreation of a realistic sound field in home
theater applications, Von Schweikert Audio has
designed a world-class wall-mount speaker
system with 180-degree dispersion and
adjustable radiation pattern. The TS-150
features the Global Axis Differential Network
which enables the speakers to recreate two
different radiation patterns for both music and
film sources. A side mounted button converts
the radiation pattern from monopole to dipole
operation: a monopole has a conventional,
forward-firing radiation pattern, while a dipole
has a diffuse, non-directional pattern.
Music and newer movies sound better with a
directional monopole speaker, but the older
movies using a mono rear channel sound better
with a dipole design, as this style “bathes” the
room with ambience; the sound is magically
“everywhere” but is also highly focused! As the
dipolar design mimics an invisible source of
sound spread out across the entire room, many
movie buffs prefer this type of sound, even
with the newer discrete digital surround sources
such as Dolby Digital and DTS.
The TS-150 is a reasonably priced surround
speaker offering both designs with correct
implementation. Finally, both music and movie
lovers can agree: the TS-150 rules!
CONE ARRAY & ENGINEERING DESIGN
In order to bathe a large room with total
surround ambience, the TS-150 is shaped as a
wedge, spreading the sound over 180 degrees.
A pair contains eight high quality, high
powered drive units: on each face is mounted a
5.5” bass/mid and 1” tweeter. For timbre
matching to other Von Schweikert Audio
speakers, the TS-150 uses special diaphragm
materials resulting in the highest Clarity Factor
available. The bass/mids have micaimpregnated cones to deliver powerful bass,
astonishing for their small size. For extremely
high transparency, the Ferrofluid-cooled dome
tweeters utilize two layers of synthetic vinyl
laminated on the silk dome to eliminate
distortion at high volume levels. Both woofer
and tweeter designs utilize our Low Distortion
Motors to handle the dynamic range and
volume levels necessary for thrilling realism
without compression or distortion.
The TS-150 can be mounted on the wall, placed
on stands, or even mounted on the ceiling,
facing down, enabling installation in any room.
Heavy duty mounting hardware is supplied, and
this model is available in Navajo White with
white grills if you wish the speaker to
“disappear.” Other finishes available are:
Black Ash, African Hazelwood, Dark Red
Cherry, and Blond Maple, all with black grills.
TS-150 SPECIFICATIONS
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 encoding.
Dipole Pattern: A “null” created by an outof-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 movie theaters.
Dispersion Angle: 180-degree dispersion
with either monopole or dipole setting,
enabling even large rooms to be filled with
ambient sound.
Driver Complement:
Woofers: Two-5.5”
bass-mids per speaker, using micaimpregnated 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 transparency.
Power Handling: 200 watts nominal input
(music power).
Frequency Response: 40Hz to 25kHz +/3dB, (60Hz to 20kHz +/- 1.5dB).
Sensitivity: 90dB @ one watt/one meter, 6
ohm nominal impedance (8 ohms
compatible).
Size and Weight: 11.5”W(rear) x 3.5”W
(front) x 11.5”H x 7”D. 16 lbs raw, 37lbs
packed.
Warranty: 10 years Parts and Labor
(excluding abuse such as burnt voice coils).
