GENERAL  DESCRIPTION

Subwoofer Systems:  Models SDB and SLB
Sound reinforcement of today's electronic  musical  instruments
and digital  quaiity  recordings  requires wide frequency

response, high power output and extended dynamic range,

making the reproduction of ultra-low frequency sound an im-
portant  factor. To complement our SD and SL Series of sound

reinforcement  speaker  systems,  the SDB and SLB were
designed to meet these  strict  requirements.
Both systems are comprised of a bass  reflex  enclosure hous-
ing a heavy duty 15-inch woofer. The low frequency cut-off is

tuned to 40 Hz for the SDB and 50 Hz for the SLB. The front
baffle of the enclosure is designed as a functional low pass
filter, thus allowing the reproduction of ultra-low frequencies

with outstanding clarity. The SDB is rated at 360 watts and

the SLB is 240 watts continuous program material.
Four 1/4" phone  jacks are provided on the rear panel for input
and bridging functions. The internal crossover input provides

access to a built-in low-pass filter  network (passive), and is
used when an  external  electronic crossover network is not
available. The direct  input  provides access to the  15"  woofer,

and is used in conjunction with an external electronic
crossover network.

The wooden enclosure is designed and constructed to prevent

resonance and sympathetic vibrations that may interfere with
the accurate  reproduction of ultra-low frequencies.  The
enclosures are equipped with large side-mounted  handles for

convenient transport, and interlocking protective corners for
multiple speaker stacking. The SDB and SLB are finished in
an attractive, scratch  resistant  polyester resin.

FEATURES

1. A  uniquely  designed  enclosure  combines a bass reflex

design with an acoustical low-pass filter to  produce ultra-
low frequencies with outstanding  clarity.

2. High power capacity  provide dynamic  range
3. Quarter  inch  phone jack terminals for input and bridging

functions.

4. Internal passive  crossover network (low-pass filter).
5. Rugged  enclosure finished in scratch-resistant  polyester

with handles and interlocking corner protectors.
