Low Frequency Enclosure

Model  SB-38S

APPEARANCE

Stands  for  the  position  of  the  gravity

center  when  the  speaker  unit  HLS38UL-8
is installed  inside.

Note:Be sure to install each speaker unit from

the inside of the enclosure baffle board.

7.  Input terminal

FEATURES

1.  Low frequency,  vented(bass-reflex)  enclosure  for  permanent  installation.

2.  Creates  a woofer  system  that  reproduces  low  frequencies  with  high  efficiencies when  the

HLS38UL-8 woofer  is  mounted. The tuning  frequency  is 45Hz.

3.  The  speaker  is  mounted  to  the  baffle  board  from  the  rear  of  the  enclosure,  facilitating

maintenance  after  installation.

4.  Creates  a  wide-range,  high-efficient  standard  speaker  system(GS-382S)  when  used  in

conjunction  with  a  LE-M94  CD  horn,  a  HFD-220-8  compression  driver,  and  a  HLS38UL-8

woofer.

5.  It is possible to suspend the SB-38W with the optional HY-38S suspension kit.

6.  It  is  easy  to  mount  the  LE-M94  to  the  enclosure  with  the  optional  HY-M94  horn  mounting
