The Electro-Voice Model LF215 is a high-performance low-frequency speaker system designed for applications where portability is important. The LF215 features two EVM15L speakers connected in parallel and mounted in a 6,5 cubic feet enclosure equipped with heavy-duty casters. The enclosure is constructed of black vinyl covered 3/4-inch plywood, with protective extruded aluminum trim and recessed handles. The rugged construction of the LF215 makes it ideal for road use.
The LF215 is designed to work well with the Electro-Voice HR series horns and DH series drivers for use in large music stage systems where a portable system is desired. The Electro-Voice XEQ-1 electronic crossover is also an ideal companion to this product.
Four rubber feet are provided on one side of the enclosure so that the LF215 may be laid on its side for stacking. Stacking will approximately halve the rated coverage angle (beamwidth) and increase the on-axis output by 6 dB. 3 dB comes because two paralleled LF215's will draw twice the power from the usual solid state amplifier. The other 3 dB comes from the reduced coverage angle.
