Design

The Lancer 77 uses an acoustic suspension cabinet design, which relies on the air inside the sealed enclosure to provide restoring force for the woofer, resulting in accurate low-frequency reproduction. The system incorporates a 10" passive radiator to augment bass output without the need for a port, and a 2" driver handles midrange and high frequencies.
