It features a high-output 12-inch woofer and a 1.75-inch titanium compression driver, each powered by a dedicated class-D amplifier within a lightweight yet durable composite enclosure.

The rear panel is designed for user-friendly connectivity and control, featuring two combination XLR/TRS inputs with independent level controls, a stereo RCA input for media players, and both XLR and RCA link outputs for easy daisy-chaining. The intuitive control set includes a two-band EQ for basic tone shaping and a ground lift switch to eliminate potential hum from connected equipment. Its built-in angled wedge design allows the speaker to be tilted back for use as a stage monitor, adding to its versatility. The inclusion of robust molded handles and a compact form factor makes it exceptionally easy to transport and position, whether used as a main speaker on a stand or as a floor monitor.
