EFS 4.2 | 4" Shallow-Mount 2-Way Component Speaker System

The EFS 4.2 from the Epic series is a high-performance, shallow-mount 4-inch component system. It's the ultimate problem-solver for vehicles with limited mounting depth, delivering premium sound where other speakers simply won't fit.

Slim Profile, Full-Size Sound

Engineered with an ultra-flat basket and a front-mounted neodymium magnet, the EFS 4.2 provides an incredibly shallow mounting depth without sacrificing performance. Paired with the detailed ET 20 WS tweeter featuring MegaSphere™ technology, this system delivers the full, dynamic sound German Maestro is famous for, even in the tightest of spaces.
