Axiom SW121HLP

The SW121HLP subwoofer is designed to deliver high-quality low frequency reproduction where very high output is a key requirement, together with well defined and deep basses and fast transient response.

The SW121HLP is a high-performance subwoofer with a special configuration based on a small cavity behind the speaker and a very compact horn. With this special design and a particular digital processing, the SW121HLA can be used as an infra-sub and it can provide an impressive low-frequency extension and a “punchy” feeling in the upper bass range.

The SW121HLP is equipped with a 21” (533mm) transducer capable of long excursion (up to 70mm peak-to-peak) and controlled by a Double Silicon Spider. The robust copper 135mm (5.3”) voice coil is wounded in four different layers both outside and inside the coil support, then improving the long term thermal capacity of the loudspeaker. Cones are made in cellulose with a special carbon fiber treatment to increase resistance and durability.
