EAW-Eastern Acoustic Wrks KF730-BLACK

The KF730 SLAM (Small Line Array Module) packs a six-driver, horn-loaded KF Series design into an amazingly compact enclosure, setting a new record for output per cubic meter.

The full-sized mid/high horn fills the entire face of the enclosure, ensuring broadband 110° horizontal pattern control. The unique Phase Aligned LF design extends horizontal pattern control into the LF and a bi-amplified powering configuration (passive mid/high) reduces total system cost and complexity.

Users can quickly and easily construct vertical arrays ranging from 4 to 18 enclosures. As with the KF760 Series, the size and configuration of a KF730 Series array defines its vertical coverage. In most cases, choosing the correct points on the multi-position fly bar will aim the array, although some radically angled configurations will require pull back using an inverted fly bar.

The rigging system permits box-to-box angles of 12°, 6°, 3°, and 1.5°, but always keeps module faces contiguous. Under normal conditions, easily hung arrays can cover listening areas ranging from appoximately +10° to -70° along the vertical axis. SLAM also permits radical array configurations that can cover any vertical angle.

The SB730 is a compact, high-powered subwoofer designed to fly above or stack below KF730 line array loudspeakers. It contains two advanced 12" woofers mounted in a "clamshell" driver arrangement, which provides tight driver coupling to increase output. A massive port radiates the considerable energy needed at the enclosure's tuning frequency to complement the KF730's output.
