DESCRIPTION
The LA400 single 12-in bass horn – known as the SuperSub,Jr.™ – contains bass horn technology that was developed forthe KF940/BH822e SuperSub dual 12-in bass horn which issetting a new standard for large-scale sub bass performance.It loads a powerful woofer on a bent bass horn to providevery high output sub bass response in a compact, portableenclosure.
The efficiency provided by EAW’s advanced horn-loadingtechniques permits the LA400 to extend overall systemfrequency to the lowest octaves. Critical listeners will berewarded with tight, punchy sub bass response without thesloppy sound associated with inferior products.
APPLICATIONS
The LA400 is engineered to work as a companion to theLA460 Virtual Array Technology full range system, as well asother high-output compact loudspeaker systems. Inaddition to complementing the LA460 to achieve optimumextended range coverage, the LA400 shares commondimensions and provides an ideal ground stacking platformfor the LA460, raising it to an appropriate height to projectHF information into an audience area.
The “towel bar” handle across the mouth of the horn andcut-away lower rear corner allows users to roll the LA400onto its rear-mounted casters with a minimum of effort.Mounting the casters on the enclosure’s rear lowers thesystem’s center of gravity during transport for easier rollingand more stable packing.

IMENSIONAL DRAWING A & E SPECIFICATIONS
The sub bass system shall incorporate a 12-in woofer. Thedriver shall be mounted on a bent bass horn constructed ofhardwood plywood veneer and structural foam.
System frequency response shall vary no more than ±3 dBfrom 45 to 250 Hz. The system shall produce a Sound Pres-sure Level (SPL) of 107 dB SPL on axis with a power input of1 Watt and shall be capable of producing a peak output of140 dB SPL on axis at 1 meter. The system shall handle 500Watts of amplifier power (AES Standard) and shall have anominal impedance of 8 ohms.
The loudspeaker enclosure shall be rectangular in shape. Itshall be constructed of 1/2-in thickness void-free cross-grain-laminated Baltic birch plywood and shall employ extensiveinternal bracing. It shall be finished in black polyurethane.Input connectors shall be dual Neutrik NL4 Speakon. Theenclosure shall include handles and rear-mounted casters.The mouth of the horn shall be covered with a powder coatedperforated steel grille.
The sub bass system shall be the EAW model LA400.TOP/BOTTOM SIDES
