Technology

A critically engineered enclosure houses this exotic driver while keeping a low profile and minimal wall thickness. The extensive internal bracing is aimed at improving rigidity. Offered in five variants, each sealed enclosure features medium-density fiberboard (MDF) construction with reinforced areas to facilitate direct-to-frame mounting.

Loudspeaker Technology

The remarkable 13TW5H driver is capable of outstanding cone excursion with minimal overall depth. It is the key to our unbeatable Fathom CTS systems.
