This sub was designed for those that wanted more than a single 18" while not having room for the 24" driver.  A pair of strong 85-lb 18" drivers utilize the full 4,000 watts of sustained power resulting in an incredibly powerful and hard-hitting subwoofer capable of producing prodigious amounts of tight, clean, articulate bass.

The only finish currently offered is a durable coating but veneer will be available as soon as we're able to secure a source for longer veneer capable of going around the full circumference of the subwoofer.

Please contact us at or 865-240-2500 to order or for any questions.  Payment can be made via PayPal or credit card.

Subwoofers currently ship within 1 to 2 weeks.  Freight shipping is an additional charge.
