Featuring gigantic, 8” diameter, triple-stacked, 360 oz. magnet motors along with custom ordered, exotic, 8-layer, flatwound-wire, aluminum dual or quad voice coils (with ohm loads of .70 - 2 ohms per coil), these drivers deliver exceptionally high magnetic force (BL factor), necessitating the use of bass-reflex (“vented”) enclosures, to convert every ounce of energy into pure SPL.

Additional special features include a heavy-duty, internally vented, cast aluminum frames, extended-gap top-plates and an extremely rugged suspension, including up to 8 heavy-duty spiders, designed to handle the pounding that are part of extreme SPL type of applications. Capable of handling over 2000 watts RMS, and up to 10,000 watts (tone-burst) these low-frequency drivers are capable of handling even twin, “strapped” monoblock amplifiers with ease.
