The QV-18B is specifically designed for KTV rooms, featuring a single 18-inch long-stroke bass-reflex design. This product delivers robust, highly detailed low-frequency performance. In large KTV room systems, the QV-18B stands out as one of the best subwoofers, capable of being stacked with multiple units to address space constraints. When arranged in layers, its low-frequency output is amplified, creating an exhilaratingly powerful and immersive bass experience.
The QV-18B, together with full-range speakers such as the QV-10, QV-12, and QV-15, forms a remarkably powerful sound reinforcement system that effectively delivers ample ultra-low-frequency energy—perfect for medium-to-small-sized club environments. The speaker features mounting holes on its top panel, allowing you to securely attach QV-10, QV-12, or QV-15 speakers at an appropriate height above the QV-18B using the optional 35mm pole mount. Additionally, this setup enables a single four-channel amplifier to power both the passive subwoofer and the full-range speakers simultaneously, creating a versatile and high-performance audio system.
