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 im­portant 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 hous­ing 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 ultra­low 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.
