Product Description

Pair, Black. Used, Excellent Condition: These two SRM450v2s in black are in mint or nearly mint condition with little to no signs of use. They were on display in our store and therefor may have suffered a light scratch or other cosmetic ding but the grill and rest of the cabinet is unblemished and they are in perfect working order. We have several to sell; these are definitely in the best condition.

 

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 RecoveryTM ampli ers 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 eld with far less material, making the woofer extremely lightweight without sacri cing 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 including 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 ampli ers if the signal drops below –45 dBu for three minutes.

The center of gravity, handle locations, handle design, position of y-points and ease of use have been ergonomically designed. There is also an integrated pole mount cup and a weather- resistant steel grille. The asymmetrical trapezoidal cabinet has been designed to provide an ideal oor 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.
