QCH 18
Summary Description
The QCH18 is a high-power low-frequency speaker featuring a single 18-inch long-stroke high-power driver. It incorporates optimized waveguide ports to maximize low-frequency efficiency. Designed for ground stacking or suspension as a subwoofer in combination with the QCH16 to extend low-frequency projection capabilities. The cabinet is constructed from premium birch plywood, with a high-strength, waterproof, and abrasion-resistant polyurethane coating on the surface. The front of the speaker is protected by a high-quality coated steel mesh combined with breathable, waterproof mesh fabric. The cabinet includes four ergonomically designed handles and a 3-point balanced suspension bracket for connecting other products from the same series. It is perfectly driven and protected by a proprietary power amplifier with professional processor presets.
The QCH18 low-profile speaker shares the same width as the QCH16, allowing for direct combination to achieve array-style hanging or ground stacking configurations
