LS-218 Dual 18" Subwoofer

• June 2024 — A former employee of Tectonic Audio Labs bought the professional division and has rebranded as FlatPanel Audio!

The LS-218 Subwoofer delivers extended low-frequency performance and dynamic range through an advanced port design that optimizes chamber size, port velocity, and acoustic loading of the dual 18-inch woofers.  The LS-218's enclosure exhibits superior sensitivity and power handling and provides increased gain over typical front-loaded designs.  Two Neutrik NL4 connectors enable the system to be run with only two individual amplifier channels driving 8 Ohm loads or a single amplifier driving a single load wired in parallel at 4 ohms.  Cabinets are designed for easy stacking, they can be used as a cardioid pattern acoustic solution when rear and side-firing low-frequency pattern control is desired.
