LD Systems MON 8A G3 Overview

From Manufacturer

Enjoy professional quality sound reproduction with the LD Systems MON 8 A G3, a compact, powered stage monitor that can double as a main PA speaker, well suited for bands, performers, DJs, and singer-songwriters. The MON 8 A G3 delivers a powerful and precise sound, thanks to the 300W RMS (1200W peak) Class-D amplifier that powers the 8" woofer and 1" high-frequency driver. The drivers are arranged in a coaxial design for true point-source performance and provide a frequency response of 68 Hz to 18 kHz with a peak SPL of 121 dB.

The rugged enclosure is made from birch plywood and features a resistant polyurea coating. The side of the speaker features two combo XLR-1/4" inputs and XLR-thru outputs, as well as two powerCON power connectors for daisy-chaining to other monitors. The second generation DynX DSP provides four application presets, a 3-band EQ, tunable notch filter, and an alignment delay. The other side of the speaker features a 35mm pole socket for raising the speaker on a stand to be used as a main PA. The MON 8 A G3 ships with a powerCON power cord.

Robust Construction
Heavy-duty birch plywood

  • The enclosures are made of heavy-duty 15mm birch plywood and coated with durable polyurea. Thus, they reliably withstand many years of hard use on the road

Steel front grille

  • The extra-strong, torsion-resistant steel grilles effectively protect the speakers

Two die-cast aluminum handles

  • The two cast aluminum handles, homogeneously integrated into the overall appearance, enable the best possible handling onstage

Recessed connections

  • The connections and controllers are recessed in steel trays and are thus optimally protected against damage

Noiseless heat sink

  • An elegantly designed heat sink on the back of the monitor provides fanless and thus noiseless cooling of the power electronics

I received the products promptly on time. One was an open box and I couldn’t tell the difference between that and the new one. I am very satisfied.

Can you link a non-powered version of this ...

Can you link a non-powered version of this speaker / I would like to power the second monitor with this speaker?
Asked by: Randall
The amplifier in the LD Systems MON 8 A G3 Powered 1200W 8" Coaxial Stage Monitor cannot be used to power a passive speaker. This monitor can only be daisy-chained with another powered monitor.
