Sound Column

Model VM-TW403

Product Overview
VM-TW403 is a compact passive linear sound column equipped with four 3-inch full-range drivers and one high-efficiency 1-inch neodymium tweeter. It delivers smooth frequency response from 120Hz to 20kHz (±3dB), with 130W RMS / 260W peak power and high 118dB SPL output at 8Ω impedance, ensuring clear vocal reproduction and powerful long-distance sound projection.
With slim dimensions of 105×145×495mm and lightweight 4.2kg design, it supports concealed wall-mounted installation. Its vertical linear array structure minimizes vertical sound reflection, ideal for conference halls, lecture rooms and banquet venues to deliver uniform, distortion-free audio coverage.
