Built upon the proven, World-Class, performance of The Bass Blaster, the SQL-2000 sets itself among some of the best sounding, most versatile, and durable woofers in it's class.

The four (4) inch copper coil comes immersed in a Jacob Fuller designed motor assembly complete with aluminum shorting pole cap, flared velocity heat-vents, and plenty of ferrite in it's dual 9.25" diameter slugs which gives it one of the highest motor forces in a woofer of it's size.

New styling gives the SQL-2000 a sleek look. A molded rubber magnet boot, laser engraved and polished backplate, and heavy aluminum dust cap add to the modern aesthetics and a classy style that's sure to blend well with almost any install.
