Dual 8" In-Wall Subwoofer

The unit fits within standard 16 wood stud walls and uses heavy-duty mounting tabs for a fast, secure installation. A magnetic, powder-coated white grille detaches easily and can be painted to match any décor, while spring-loaded binding posts simplify speaker-wire connections.

Questions about this item

What frequency range does the 36 to 200 Hz response cover in practice?

The 36 to 200 Hz range reproduces deep bass fundamentals and low midrange, letting the dual 8" woofers handle movie effects and music bass down to the lowest octave.

What wall cavity depth is required for the 16 inch stud mounting?

The speaker is designed to fit within standard 16 inch wood stud walls, so a typical 3.5 inch deep cavity between studs provides enough clearance for the enclosure and mounting tabs.

How are the spring loaded binding posts wired during installation?

Strip each speaker wire, press down the spring loaded post, insert the bare conductor, then release; the post clamps securely and the magnetic grille snaps on last to finish the job.
