June 2023 — Investors have shut down the professional division of Tectonic Audio Labs, and are focusing all of their energies on OEM products. At this time, no Tectonic equipment is available.

We are aware of efforts to revive the professional division, and will update this page when we know more.

The Tectonic LS-118 Subwoofer delivers excellent dynamics and output from a compact cabinet profile that can be easily ground-stacked or hung in multiples of two, three, or four units. It uses a front-loaded, single 18-inch woofer that features a bent bass reflex port. Rated to handle 2400 Watts of program power and 3600 Watts of peak power, the LS-118 is compatible with Tectonic Distributed Mode Loudspeakers (DMLs) and other mid to high-frequency loudspeaker systems.
