Sub-bass reinforcement speaker designed as a companion to our SX series line of full range speaker enclosures, the SXsub has proven itself to be worthy of any extended low frequency response duty. Capable of extremely high sound pressure levels, this enclosure is the perfect match when used in conjunction with other Adamson enclosures...extending low end frequency response to below 40Hz. The SXsub is equipped with 2 AW18 Kevlar bass drivers mounted in a tuned, vented and heavily braced cabinet. Supplied with integral castors for easy tilt and roll, this cabinet is lightweight, compact and powerful.
