Toa SW-46S-UL2 Specifications

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 effi-
ciency, super-low frequency range, and faithful reproduction
are required, such as discos, concert halls, theaters, movie
houses, auditoriums, and in live sound reinforcement appli-
cations.
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 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 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
TOA SPEAKER SYSTEM
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.
