SRM450v2

The Mackie SRM450v2 is a full-range, portable, powered

loudspeaker system providing high-output, ultra-wide

dispersion and low-distortion performance in a compact,

lightweight design. Two Fast Recovery™ ampliﬁers

independently power a 12-inch lightweight woofer and a

precision titanium compression driver. Mackie’s

sophisticated Active electronics provide phase correction,

crossover, time correction, equalization and protection

circuitry.

A heat-treated titanium compression driver with multi-cell

aperture directs pristine highs through an exponential high-

frequency waveguide, allowing for ultra-wide dispersion.

This allows the SRM450v2 to deliver clear, smooth sound to

audience members up to 45° off axis.

The 12-inch lightweight woofer provides a greater magnetic

ﬁeld with far less material, making the woofer extremely

lightweight without sacriﬁcing performance. The 3-inch voice

coil allows the driver to run cooler, delivering consistent

performance even after long hours of use.

Mackie-designed Active electronics provide equalization,

crossover, time alignment, and phase correction to enhance

sonic performance. Protective circuitry includes

over-excursion protection, low-line voltage shut-down,

thermal protection, level dependent low-frequency roll-off and

independent LF and HF limiters.

The SRM450v2 features a number of dedicated controls

includ

ing a mic/line switch, a single microphone and line input

level control,

and a contour switch for low-level sound

reinforcement applications. There is also a timed turnoff feature

that turns off the ampliﬁers if the signal drops below –45 dBu

for three minutes.

The center of gravity, handle locations, handle design, position

of ﬂy-points and ease of use have been ergonomically designed.

There is also an integrated pole mount cup and a weather-

resis

tant steel grille. The asymmetrical trapezoidal cabinet has

been designed to provide an ideal ﬂoor monitoring position.

The cabinet is constructed of high-pressure injected

polypropylene. The enclosure features ample amounts of

reinforcement ribbing and structural strengthening resulting

in a strong, super-rigid design providing ideal acoustical

characteristics.

APPLICATIONS

Small to mid-size club/band PA systems, houses of worship,

DJs, vocal/band monitor wedges, gymnasiums, banquet

halls, conference rooms and many, many more.
