The use of a long-excursion 200 mm woofer combined with a 250 mm passive radiator reflex system made it possible to create a “small” subwoofer capable of providing huge output with excellent musicality. The 15/18 mm MDF enclosure is reinforced with internal bracing and covered with thick moquette to reduce losses in the system. The compact size, the refined cosmetic finish along with the reversible logo makes the EBX range the “solution” enclosure for any installation.
