DESCRIPTION
The KF730P Series is a compact, fixed installation, line array
systemthatsetsaperformancebenchmarkabovesimilarsystems.
Itdelivers3-way, KF Series performance in a flexible,easy-to-use
system that can deliver concert-level output in an exceptionally
widerangeofvenues.TheKF730Pisanexcellentsolutionforfixed
installationapplications 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,andstage/performercoverage.
OnelargeMF/HFhornfillstheentirefaceoftheenclosure,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
theLF beamwidthmatchesthe MFthroughcrossover.
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
enclosurestogether. Thisriggingsystemisfullycompatiblewith
thecompanionSB730Psubwoofer.Six yearwarranty.
3-WAY FULL-RANGE BI-AMP(passive MF/HF filter)
Performance is for a single KF730P.Array performance is determined using the KF730 Wizard.
