PROFESSIONAL SOUND SYSTEM

Super  Woofer  System

SW-46W-UL2

Model SW-46S-UL2

GENERAL  DESCRIPTION

The Toa  SW series  Super Woofers  are  super-low frequency

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  rein-
forcement  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"  (100mm)  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  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  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  removing  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  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  18"  woofer  provides  high  effi-

ciency  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  re-
spective  amplifiers  (46W).

5.  Two  mountable  female  XLR  connectors  (46W)  or  one

each  of  male  and  female  XLR  connector  (46S).

6.  Rugged,  grey-painted  enclosure  with  carrying  handles

and  a  detachable  punched  grille.
