SPECIFICATIONS LA400

DESCRIPTION

The LA400 single 12-in bass horn – known as the SuperSub, Jr.™ – contains bass horn technology that was developed for the KF940/BH822e SuperSub dual 12-in bass horn which is setting a new standard for large-scale sub bass performance. It loads a powerful woofer on a bent bass horn to provide very high output sub bass response in a compact, portable enclosure.

The efficiency provided by EAW’s advanced horn-loading techniques permits the LA400 to extend overall system frequency to the lowest octaves. Critical listeners will be rewarded with tight, punchy sub bass response without the sloppy sound associated with inferior products.

APPLICATIONS

The LA400 is engineered to work as a companion to the LA460 Virtual Array Technology full range system, as well as other high-output compact loudspeaker systems. In addition to complementing the LA460 to achieve optimum extended range coverage, the LA400 shares common dimensions and provides an ideal ground stacking platform for the LA460, raising it to an appropriate height to project HF information into an audience area.

The “towel bar” handle across the mouth of the horn and cut-away lower rear corner allows users to roll the LA400 onto its rear-mounted casters with a minimum of effort. Mounting the casters on the enclosure’s rear lowers the system’s center of gravity during transport for easier rolling and more stable packing. A stout grill protects the drivers from objects that might fall into the horn when on its back.
