Notes

This system is comprised of the Mach 5 UXL-18 driver in the 4.2 cubic foot sealed test enclosure used for 18 drivers. This is a capable system with decent sensitivity for the enclosure size and type of extra long throw driver used. The response shape is good with a modest hump centered at about 55Hz and a very mild 4dB roll off by 200Hz which is not bad for a driver with a motor and voice coil containing this much mass. Output headroom is generous particularly in the very deep bass frequencies and compression performance is good as well. Response shape does not change much even at very high power and excursions. Distortion performance appears to be good but the distortion testing was not fully completed. This system gives a good accounting of itself in all of the major metrics.
