DESCRIPTION

The KF730 Series is a compact line array system that sets a
performance benchmark above similar systems. It delivers
3-way, KF Series performance in a flexible, easy-to-use system
that can deliver concert-level output in an exceptionally wide
range of venues. The KF730 is an excellent compact line array
solution for applications such as houses of worship, corporate
A/V, theatres, hotel ballrooms, and concert halls. The system is
also ideal for supplemental coverage for larger line arrays, such
as the KF760 Series. Such uses include audience side fill, stage
lip fill, delayed arrays for balconies, and stage/performer
coverage.

One large MF/HF horn fills the entire face of the enclosure,
better maintaining horizontal pattern control throughout the
MF/HF passband. The curved aperture MF loading slots
effectively move the MF acoustic origin further into the horn than
physical space permits. The side-mounted LF drivers provide a
forward-firing, figure eight type pattern. The drivers are spaced
so that the LF beamwidth matches the MF through crossover.

The KF730s are sized to truck-pack friendly dimensions. The
rigging system is fully compatible with the companion SB730
subwoofer.

3-WAY FULL-RANGE BI-AMP (passive MF/HF filter)

Performance is for a single KF730. Array performance is determined using the KF730 Wizard.
