DESCRIPTION
The KF730P Series is a compact, fixed installation, 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 KF730Pis an excellent solution for fixed
installation applications such as houses of worship, theatres, hotel
ballrooms, arenas, 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, 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 KF730P input features barrier strip terminals. A separate
terminal strip is provided for loop-through connection for daisy-
chaining additional KF730Ps.
The KF730P is configured using
the included KF730P Splay Angle Brackets to bolt the
enclosures together. This rigging system is fully compatible with
the companion SB730Psubwoofer. Six year warranty.
3-WAY FULL-RANGE BI-AMP (passive MF/HF filter)
Performance is for a single KF730P. Array performance is determined using the KF730 Wizard.
