Loudspeaker
General Description
Technical Information
1
Band-limited pink noise is applied to the MB4 speaker and amplified to a level at the loudspeaker
terminals corresponding to 1 Watt as referenced to the nominal impedance. The average sound
pressure level (dB-SPL) is measured at 1 meter from the speaker in an anechoic environment.
2
Band-limited pink noise is applied to the MB4 speaker and amplified to a level at the loudspeaker
terminals corresponding to the long-term rated power handling of the speaker. The average sound
pressure level (dB-SPL) is measured at 1 meter from the speaker in an anechoic environment.
3
Band-limited noise, meeting the IEC Standard #268-5 is applied to the MB4 speaker and amplified
to a level at the loudspeaker terminals corresponding to the power handling of the loudspeaker. The
loudspeaker must show no visible damage or measurable loss of performance after 100 hours of
continuous testing.
Enclosure construction: High-density
MultiFiber multi-layer wood particle
panel with high-impact foamed
polypropylene end caps.
The PANARAY MB4 Modular bass
loudspeaker is a 200W, low-fre-
quency loudspeaker that can be
used for indoor permanent installa-
tions and for portable applications.
Multiple MB4 speakers can be
combined to effectively create a
larger single bass source resulting in
higher SPL.
The MB4 speaker’s output, band-
width and size make it useful as a
single bass unit, or as a modular
building block to match other Bose
®
products in most professional
systems.
The MB4 speaker can also be
configured using MB4 Endfire or
Broadside bass array spacing,
described in the MB4 bass array
sheet (PC 031395), and the
PANARAY system digital controller to
create directional bass.
The PANARAY MB4 Modular bass
loudspeaker offers the following
features:
• Wide frequency range, from 40Hz
to 300Hz, which can be easily
matched to any Bose professional
loudspeaker
• High impact output for dominant
bass material
• Rugged portable enclosure with
metal grille and carrying handles
• Distinctive styling
• Recessed back plate with two
Speakon
®
NL4 connectors
The MB4 speaker can be used with
the Bose PANARAY system digital
controller to provide smooth accu-
rate spectral response over the entire
operating range of the system.
The MB4 speaker can also be used
with the Bose 1600 or 1800 amplifi-
ers in combination with the MB4
plug-in EQ card to provide active
equalization for the system.

A single MB4 speaker is well
matched in output and bandwidth to
one or two PANARAY 402

A
or MA12 loudspeakers, providing a
full-range solution for distributed or
portable systems.
Two or three MB4 speakers are a
good match for higher-output
loudspeakers, like the PANARAY
802
®
-III speaker, for engineered or
portable systems.
For larger spaces that require even
higher SPL, four or more MB4
speakers can be combined with each
PANARAY LT series loudspeaker.
