Model 2215 is a professional quality low frequency transducer capable of handling high power with negligible distortion. Overall sensitivity is controlled to give linear response lower in frequency than any other 15-inch loudspeaker. The 2215 was designed for critical monitoring applications where linear bass response with lowest possible distortion is required rather than high mid-range efficiency. Optimum performance is realized in an enclosure having 6-9 cubic feet internal volume.
