VHD4.18 VHD Subwoofer Enclosure

The VHD 4.18 is a quad 18”subwoofer system comprising of four individual loudspeaker cabinets. The objective is to make the system easy to transport and setup. When assembled, the VHD 4.18 system becomes a high efficiency neodymium subwoofer system with immense output. The system was designed with very high sensitivity in mind; it provides 110 dB at 1W/1m and a tremendous output of 149dB when running at full power. Each cabinet incorporates a large port area that becomes an optimized horn aperture when all four cabinets are assembled. The quad 18” subwoofer system delivers extreme output, controlled low frequencies and resolution. It also comes with integrated Fly-Track for securing on the ground or where flying the subwoofers is a preference.
