• Horn-loaded for efficiency and high output
• Companion to KF760 Series Line Array
• Sized for efficient truck packing
• Response to 29 Hz to capture lowest
musical notes
• Enclosure pads nest together for stacking ability
The BH760 bent horn subwoofer is engineered as both a com-
plement to the KF760 Series Line Array loudspeaker systems
and as a bass supplement to any audio system. BH760s pro-
vide extremely high levels of tight, punchy bass response to
the lowest octave. Its balanced horn design allows it to be
used singly or in multiples. The horns of multiple enclosures
couple acoustically to create a single, larger horn that
increases output and provides directivity to very low frequen-
cies. Optimum performance is achieved when used in arrays of
four or more enclosures.
The enclosure features a system of interlocking pads and
grooves to facilitate stable ground stacks. Compact dimen-
sions, well-placed handles and an optional caster pallet
enhance portability. At 45-in deep, the enclosures pack uni-
formly with the KF760 Series loudspeakers as well as standard
width road cases. Six year warranty.

• Concert Touring • Club Systems

The horn-loaded subwoofer shall utilize bent horn technology
to provide a bass horn length of over 10 feet in a 30-in wide,
40-in deep, 30-in high enclosure. The system shall incorpo-
rate two 12-in cone transducers.
System frequency response shall vary no more than +3 dB from
29 Hz to 100 Hz. The subwoofer shall produce a sound pres-
sure level (SPL) of 107 dB on axis at 1 meter with a power
input of 1 watt, and shall be capable of producing a peak out-
put of 145 dB SPL on axis at 1 meter. The subwoofer shall
handle 1600 watts of amplifier power (continuous) when used
with a 24dB/octave Butterworth high pass filter, and 1000
watts of amplifier power (continuous) without a high pass fil-
ter. It shall have a nominal impedance of 4 ohms.
The subwoofer enclosure shall be constructed of exterior grade
Baltic birch plywood and shall employ extensive internal brac-
ing. It shall be finished in a wear resistant textured black
paint. The enclosure shall have heavy-duty handles and inte-
gral skids with companion recesses so that enclosures inter-
lock for stability when stacked. A caster pallet shall be avail-
able as an optional accessory. Input connectors shall be two
Neutrik NL4 Speakon. The front of the subwoofer shall be cov-
ered with a powder coated perforated steel grille.
The horn-loaded subwoofer shall be the EAW model BH760.
