Description
The LA400 uses bass horn technology that was developed for the KF940 SuperSub?. It loads a powerful 12 inch woofer on an expanding bass horn that is eight feet in length, and provides extremely 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.
The LA400 is designed to be easily transportable. 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 grille protects the drivers from objects that might fall into the horn when on its back.
Applications
The LA400 defies conventional wisdom, which states that an 18 inch woofer is required to drive a bass horn. 18 inch woofers simply do not have the rigidity required to drive the high acoustic impedance present in a horn throat. As a result, traditional 18 inch bass bins get loud, but only produce one note very well. The LA400 in contrast uses a proprietary heavy duty 12 inch woofer. The woofer has the motor structure of a traditional 18 inch device, and its cone is reinforced to be a better engine for compact horn-loading. This woofer is then loaded onto a properly designed bass horn which matches path length to cone area and maximizes driver efficiency. The result is tight, punchy sub bass response that not only will shake your foundation, but is articulate and musical as well.
The horns of multiple enclosures couple acoustically to create a single, larger horn that increases output and provides directivity to very low frequencies. Factory-recommended digital processor settings will enhance LF performance even more. The LA400 is engineered to work as a companion to LA Series full range systems, as well as other high-output compact loudspeaker systems. Laid on its side the LA400 is only 21 inches high, which also makes it very effective in clubs and theatres where subs must be intalled under a low stage.
