TECHNICAL SPECIFICATIONS BH822e

DESCRIPTION

The BH822e bent bass horn subwoofer represents the next
step forward in large format subbass reproduction. Widely
known as the SuperSub™, the system in designed for use in
arrays of four or more which produce extremely high output
sub bass response to the very bottom of the audible
spectrum.

The 13-ft bent horn loads 2x 12-in woofers specially
designed to endure the extreme conditions the SuperSub
imposes. An array of four BH822e’s will produce a maximum
output of 146.0 dB at 28 Hz and features -3 dB and -10 dB
points of 24 Hz and 21 Hz, respectively.

APPLICATIONS

The BH822e subwoofer system is engineered for use in
arrays of four or more modules and are appropriate in any
application requiring extremely high output levels of sub
bass information.

Relatively small SuperSub arrays will fill the largest domed
stadiums, arenas, houses of worship, theaters and perform­ing arts centers with high impact sub bass information.

The BH822e is optimized for permanent installation only.
Six year warranty.

Applications include:

Stadiums
Large Nightclubs
Large Houses of Worship
Performing Arts Center
Large Theater

The sub bass system shall incorporate 2x 12-in woofers. The
drivers shall be mounted on a bent bass horn with a
pathlength of at least 13 feet constructed of hardwood ply­wood veneer and structural foam.

System frequency response shall vary no more than ±3 dB
from 24 to 300 Hz. The system shall produce a Sound Pres­sure Level (SPL) of 109 dB SPL on axis with a power input of
1 Watt and shall be capable of producing a peak output of
145 dB SPL on axis at 1 meter. The system shall handle 1000
Watts of amplifier power (AES Standard) and shall have a
nominal impedance of 2x 8 ohms.

The loudspeaker enclosure shall be rectangular in shape. It
