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.

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.

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.

MB4 Loudspeaker

Combinations

Incremental bass output can be

achieved by combining multiple MB4

units in close proximity.

# of PANARAY MB4s

A single MB4 speaker is well

matched in output and bandwidth to

one or two PANARAY 402

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.

PANARAY

MB4 Modular Bass

Loudspeaker

General Description

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.

Max Output (dB)

The PANARAY MB4 Modular bass

110

loudspeaker offers the following

116

features:

119

• Wide frequency range, from 40Hz

122

to 300Hz, which can be easily

matched to any Bose professional

loudspeaker

-II, 502

• High impact output for dominant

bass material

• Rugged portable enclosure with

metal grille and carrying handles

• Distinctive styling

• Recessed back plate with two

Speakon

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.
