Super Woofer System
SW-46W-UL2
Model SW-46S-UL2
GENERAL DESCRIPTION
The Toa SW series Super Woofers are super-low frequency
loudspeaker systems desi ned for professional applica-
tions in hi h-level sound reinforcement environments where
hi h efficiency, super-low frequency ran e, and faithful re-
production are required, such as discos, concert halls,
theaters, movie houses, auditoriums, and in live sound rein-
forcement applications.
The SW-46S bass-reflex enclosure contains one (1) ultra-
linear, hi h-power 18" woofer, while the SW-46W contains
two 18" woofers.
The woofer, Model HLS46UL2-8, employs a 4" (100mm) di-
ameter voice coil of ed e-wound copper ribbon on an alu-
minum coil form, which is driven by powerful double ferrite
ma nets. The ma nets are supported by a ru ed diecast
aluminum frame and ive a flux density of 13,600 auss.
Bass-reflex ports are tuned to the optimum condition by
computer, allowin the woofer to provide maximum per-
formance.
The system is rated at 480 watts RMS (240 watts RMS for
46S) of continuous pink noise, and at 1,440 watts (720
watts for 46S) of continuous pro ram material.
Two pairs of screwtype input terminal (one-pair of terminals
in the case of the 46S) is provided on rear of enclosure.
Removal of the jumper pieces permit the 46W to drive the
two woofers independently by their respective amplifiers.
By removin blank panels on the rear-mounted input panel,
two female XLR connectors (46W) or one each of male and
female XLR connector (46S) can be mounted. The enclo-
sure is hi hly reinforced to eliminate unwanted vibrations.
Lar e carryin handles are provided on both sides of an
enclosure, and a detachable punched metal rille in front.
The enclosure is finished in rey paintin .
FEATURES
1. Ultra linear, hi h power 18" woofer provides hi h effi-
ciency in the super-low frequency ran e.
2. Hi h power handlin capacity of 480 watts (240 watts
for 46S) RMS continuous pink noise and 1,440 watts
(720 watts for 46S) continuous pro ram material.
3. Bass-reflex enclosure tuned to the optimum conditions
by computer assures the maximum woofer performance.
4. Screwtype input terminal (2 pairs for 46W and 1 pair for
46S) are provided. By removin jumper pieces two
woofers can be driven independently by means of re-
spective amplifiers (46W).
5. Two mountable female XLR connectors (46W) or one
each of male and female XLR connector (46S).
6. Ru ed, rey-painted enclosure with carryin handles
and a detachable punched rille.

The two woofers of the SW-46W-UL2 are connected in pa-
rallel when jumper pieces are used (impedance is 4
ohms). Removal of the jumper pieces disconnect the two
woofers from each other, allowin each of them to be
driven independently by means of their respective ampli-
fiers (impedance of each is 8 ohms). By removin the
blank panels two female XLR connectors (46W) or one
each of male and female XLR connector (46S) can be
mounted. To do wirin work, remove the rear-mounted in-
put panel.
