QM-210L

Passive Line Array Speaker

The QM-210L is a compact passive line array element that delivers high sound pressure and precise vertical control for live sound and installed applications. Dual 10-inch ferrite low-frequency drivers are paired with a 1.4-inch exit neodymium high-frequency driver with a 3-inch voice coil, loaded by a planar waveguide for a tightly controlled 100° × 15° coverage pattern. A built-in 1.3 kHz passive crossover with bi-amp switching allows the system to be run passively or actively, with Quest QXD amplifiers providing dedicated DSP presets and control.

 

The marine plywood enclosure is finished in a waterproof, wear-resistant and UV-resistant polyurea coating, with a steel mesh grille backed by polyester fibre fabric. An integrated aluminium rigging system with stainless-steel quick-release pins, together with short and long fly bars, allows fast, repeatable array deployment. The QM-210L is backed by a 5-year warranty.

QM-218S SUBWOOFER

18" Installation Subwoofer

The Qmotion QM-218S is a high-power dual 18-inch subwoofer engineered to deliver deep, authoritative low-frequency extension for demanding live sound and fixed installation applications. Two 18-inch ferrite drivers provide high output with clarity and control, extending down to 25 Hz (−10 dB) with a calculated peak output of 142.8 dB SPL. It complements Qmotion line array system, and Quest QXD amplifiers provide the power, DSP presets and control.

 

The marine plywood enclosure is finished in a waterproof, wear-resistant and UV-resistant polyurea coating and protected by a steel mesh grille with polyester fibre fabric. speakON connections on both the front and rear panels make cabling flexible. Two handles per side, stacking feet and front wheel board locks make transport and ground-stacking quick and secure. The QM-218S is backed by a 5-year warranty.
