Active installation subwoofer, black

8" active subwoofer with 10" passive radiator
Sleek, low-profile design with rugged aluminum casing

DSP presets for DQOR® speakers or HPF for any speaker
Optional surface mount box (wall + ceiling) with hinges for easy installation

The DQOR® SUB 8 A from the DQOR® series is an active subwoofer for indoor installation with an 8" woofer and a 10" passive radiator. It has two 140 W RMS power outputs that have been specially designed for connecting external full-range speakers. These outputs are fine-tuned using the DSP presets to ensure optimal audio pairing with DQOR® series speakers or any other speaker.

Designed for high performance in a compact form factor, it enables a powerful 2.1 audio system without the need for separate amplifier racks.

Combining aesthetics with powerful audio performance, the DQOR® SUB 8A's clean, low-profile design makes it an elegant addition to any room. Delivering 250W RMS, it provides impressive sound quality with up to 108dB SPL and an extension of low frequencies down to 37Hz.

The DQOR® SUB 8 A has rubber feet for placement on the floor or can be easily installed with the optional surface mount bracket. This offers flexible mounting options, holes for clean cable management, locking screws, a security lock and a hinge mechanism for quick mounting.

Four terminal blocks allow for balanced stereo input, VCA volume control and remote standby. Dip-switch selectable features include stereo/mono mode, auto standby mode and DSP preset.

The active indoor subwoofer can be used in many different areas, such as hospitality, retail, entertainment or corporate.

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