Model details
A birch-cabinet powered subwoofer for portable PA and playback. Two line-level inputs sum internally, with separate through outputs for the connected system. Its 18-inch driver and internal 1000 W amplifier provide the low-frequency section without a separate power amp. The XLR through outputs are full range, so filtering for the main speakers must be handled by their own settings or the system processor rather than assumed at the sub output.
Typical uses: Band PA · DJ playback · Portable event bass support
