PROFESSIONAL SOUND SYSTEM

Super  Woofer  System

SW-38W-UL

Model SW-38S-UL

GENERAL DESCRIPTION

The TOA SW series Super Woofers are super-low  frequen-
cy loudspeaker systems designed for professional applica-
tions in high-level sound reinforcement environments where
high efficiency, super-low frequency range, and faithful re-
production are required, such as discos, concert halls,

theaters,  movie houses, auditoriums, and in live sound

reinforcement applications.

The SW-38S bass-reflex enclosure contains one (1) ultra-

linear, high-power 15" woofer, while the SW-38W contains

two 15" woofers.
The woofer,  Model HLS38UL-8, employs a 2.8" (72mm) di-
ameter  voice coil of edge-wound copper ribbon on an alu-

minum coil form, which is driven by powerful  double  ferrite
magnets. The magnets are supported by a rugged diecast

aluminum  frame and give a flux density of 14,200 gauss.
Bass-reflex  ports are tuned to the optimum condition by
computer, allowing the woofer to provide maximum per-

formance.
The system is rated at 300 watts RMS (150 watts RMS for
38S) of continuous pink noise,  and at 900 watts (450 watts
for 38S) of continuous program  material.
Two pairs of screwtype input terminal  (one-pair of terminals
in the case of the 38S) is provided on  rear of enclosure.
Removal  of the jumper pieces permit the 38W to drive the

two woofers independently by their respective amplifiers.

By removing blank panels on the rear-mounted input
panel, two female XLR connectors (38W) or one each of

male and female XLR connector (38S) can be mounted.
The enclosure is highly reinforced to eliminate unwanted
vibrations.Large carrying  handles are provided on both
sides of an enclosure, and a detachable punched metal
grille in front. The enclosure is finished in grey painting.

FEATURES

1. Ultra linear, high power 15" woofer provides high effi-

ciency in the super-low frequency  range.

2. High power handling capacity of 300 watts (150 watts

for 38S) RMS continuous pink noise and 900 watts (450
watts for 38S) continuous program material.

3. Bass-reflex enclosure tuned to the optimum conditions

by computer assures the maximum  woofer  perform-

ance.

4.  Screwtype input terminal  (2  pairs for 38W and  1  pair for

38S) are provided.  By removing jumper pieces two
woofers can be driven independently by means of re-
spective amplifiers (38W).

5. Two mountable female XLR connectors  (38W) or one

each of male and female XLR connector (38S).

6. Rugged, grey-painted enclosure with carrying handles

and a detachable punched grille.
