IMG Stageline SP-46A/500 Professional PA Subwoofer 2000WMax. 8ohm 18"

Subwoofer with extra low limit frequency, but at the same time of optimum high efficiency, mechanically ultra-stable due to double centering spiders - professional bass speakers for extra subwoofer power.

With double centering and parameters for an ultimatively deep bass, even in moderate cabinets. Nevertheless, the efficiency is outstandingly high. The long excursion allows the stable mechanical conversion of the extra high power rating, a subwoofer for a really deep sound. Suitable for any professional application, from discotheque to stage.
