Part of the DQOR® series, the DQOR® SUB 8 A is a powered indoor installation subwoofer with an 8" woofer and a 10" passive radiator. It features two 140 W RMS powered outputs, specifically designed for connecting external full-range loudspeakers. These outputs are fine-tuned by DSP presets to ensure an optimal audio pairing with DQOR® series loudspeakers or any other loudspeaker.

Designed for high performance in a compact form factor, it enables a powerful 2.1 audio system with no need for separate amplifier racks.

The clean and low-profile design ensures the DQOR® SUB 8 A is a sleek addition to any room, combining aesthetics with powerful audio performance. Rated at 250 W RMS, it delivers impressive sound quality at up to 108 dB SPL with low frequency extension down to 37 Hz.

The DQOR® SUB 8 A has rubber feet for floor mounting, or it can be easily installed with the optional surface mount bracket, which includes flexible mounting options, holes for clean cable management, locking screws, a safety-locking mechanism, and a hinge mechanism for quick setup.

Four terminal block connectors allow for balanced stereo input, VCA volume control and remote standby control. Dip switches allow for stereo/mono mode, auto standby mode and DSP preset selection.

The indoor installation subwoofer can be used in a wide variety of applications including hospitality, retail, entertainment or corporate settings.

It is available in two colours: black (RAL9005) and white (RAL9016).
