Low end that frees your tops
A full-range speaker that also reproduces the lowest octaves hits its limit early and loses midrange clarity. The sub takes over the bottom end, and the XLR High Pass outputs send a bass-free signal to the tops so they play cleaner and louder. Crossover modes tailor the low end to the speakers you pair it with, and the polarity switch helps you line up phase.
Growing the system and moving it
Two XLR inputs take a stereo feed from the desk or the tops. Full-range outputs with a mono button chain more subs, so the system grows without an extra mixer. The level control mutes fully, handles make carrying easier and the M20 thread takes an SPM400 speaker pole (sold separately). Paired with Thump12V4 or Thump15V4 speakers, you run the sub's high-pass output to the tops and the lowest band stays in the subwoofer, so the tops no longer have to reproduce it. The cabinet has built-in handles, and the 31.9 kg weight is worth planning around when you load a vehicle. Two XLR inputs take a stereo feed straight from the desk, and the mono button on the full-range output lets you chain several subwoofers in one path.
