Product Overview

Active Speaker 2 x 8"/1" 750W

The DVX DM28 excels at rendering speech and vocals. Users’ search for natural response, dynamic balance, and high SPL in a compact, inconspicuous package ends with this stage monitor.

The ultra low-profile enclosure sports two 8" RCF® neodymium woofers with large 2.5" voice coils that go about their business of rendering signals with impressive precision. In contrast to cabinets loaded with simple 8” speakers, the DVX DM28 packs a mighty low-midrange punch. What’s more, it responds far faster to transients in the signal, rendering each attack with awesome accuracy and power. Offering far greater dynamic range, it outperforms standard 12" systems by a combination of asymmetrical CD horn and precision-matched 1" RCF® neodymium compression driver efficiently couples high frequencies.

The digipro®  digital power amp featuring a PFC switched-mode power supply and the speakers are fine-tuned to minimize the risk of feedback, ensuring the DVX DM28 remains remarkably feedback resistant even at peak SPL. Made of rugged multiplex and coated with tough black lacquer, its light low-profile enclosure sets up at two different angles. The integrated controller acts as the enclosure’s controller, serving as an active equalizer, active x-over with phase and delay time alignment, and controlling the onboard limiter.
