TOA SPEAKER SYSTEM
SUPER WOOFER SYSTEM
SW-46W-UL2/SW-46S-UL2
DESCRIPTION
The TOA SW series Super Woofers are super-low frequency
loudspeaker system designed for professional applications in
high-level sound reinforcement environments where high efficiency, super-low frequency range, and faithful reproduction
are required, such as discos, concert halls, theaters, movie
houses, auditoriums, and in live sound reinforcement applications.
The SW-46S bass-reflex enclosure contains one (1) ultra-
linear, high-power 18” woofer, while the SW-46W contains
two 18” woofers.
The woofer, Model HLS46UL2-8, employs a 4” (100 mm)
diameter voice coil of edge-copper ribbon on an aluminum
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 13,600 gauss.
Bass-reflex ports are tuned to the optimum condition by
computer, allowing the woofer to provide maximum performance.
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 program material.
Two pairs of screwtype input terminals (one-pair of terminals
in the case of the 46S) are provided on rear of enclosure.
Removal of the jumper pieces permits the 46W to drive the
two woofers independently by their respective amplifiers. By
removing blank panels on the rear-mounted input panel, two
female XLR connectors (46W) or one each of male and
female XLR connectors (46S) 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 gray painting.
FEATURES
1. Ultra-linear, high power 18” woofer provides high efficiency in the super-low frequency range.
2. High power handling capacity of 480 watts (240 watts for
46S) RMS continuous pink noise and 1,440 watts (720
watts for 46S) continuous program 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 removing jumper pieces two woofers can be driven independently by means of respective
amplifiers (46W).
5. Two mountable female XLR connectors (46W) or one
each of male and female XLR connectors (46S).
6. Rugged, gray-painted enclosure with carrying handles
and a detachable punched grille.

The two woofers of the SW-46W-UL2 are connected in
parallel when jumper pieces are used (impedance is 4
ohms). Removal of the jumper pieces disconnects the
two woofers from each other, allowing each of them
to be driven independently by means of their respective
Screwtype terminals
amplifiers (impedance of each is 8 ohms). By removing
the blank panels two female XLR connectors (46W) or
one each of male and female XLR connector (46S) can
be mounted. To do wiring work, remove the rearmounted input panel.
