James Loudspeaker EMB15-DF - Passive 15" In Room Down Firing Subwoofer

Product Overview

The James Loudspeaker EMB15-DF is a passive 15" in-room subwoofer with a down-firing driver, built for commercial AV rooms that demand the deepest floor-coupled bass in the EMB range. Its downward-facing 15-inch driver loads powerful low frequencies into the room, making this down-firing in-room subwoofer suited to large theaters, auditoriums, and high-end residential installations. As a passive sub, it operates from an external subwoofer amplifier. The EMB15-DF gives integrators a finished-cabinet option with the largest driver displacement in the family.

Product Description

The EMB15-DF is part of the James Loudspeaker EMB family of passive in-room subwoofers, where the number denotes driver size and the suffix denotes firing direction. This model combines a single 15-inch driver with a down-firing orientation, directing deep low-frequency output toward the floor for even room loading. Because it is passive, the EMB15-DF requires an external subwoofer amplifier, leaving power and processing in the integrator's hands. It is the largest in-room down-firing model in the range, stepping up in displacement from the EMB12-DF and the EMB10-DF. The finished cabinet supports visible in-room placement without an in-wall build. The full range is shown in the James Loudspeaker collection. This makes the EMB15-DF a strong specification for large rooms that demand high-output floor-coupled bass.
