The 3/4” MDF enclosure uses dado “lock-joint” and rabbet construction on CNC-fabricated panels to ensure resonance-free response and long-term reliability. The internal high-current passive crossover features the proprietary high-power thermal overload KLIP- circuit, which limits potential damage to the high-frequency driver. Mounting capabilities include top and bottom attachments for the optional SB-102 "U"-shaped bracket.
