The WMD 1803 is a 1 x 18’’ extremely efficient long throw subwoofer, specifically designed for big indoor and outdoors venues. The 2.8m length of the horn gives it a huge amount of gain + beam and as
there are no parallel sides within the box we have eliminated ÔboomingÕ. Our WAVE FRONT REFRACTION“ ensures punchy, pure sub clarity. The WMD 1803 is designed to be used in pairs, as the boxes are not symmetrical on the inside. This means that a pair can be set up to be directional, or very directional. The more WMD 1803’s you have, the more efficient each one becomes. They also can be used in conjunction with VSB 218 to achieve the full sub spectrum. The WMD 1803 has a useable frequency range from 30Hz-125Hz.
1 x WMD 1803 will give you 107dB SPL @1w/1m. Maximum continuous SPL 137dB @1m.
