All specifications are therefore subject to change without notice. Part Number: RD0093 (C) KF730 SPEC August 2003 K F 7 3 0 S p e c i f i c a t i o n s group · S FEATURES Highest output to size ratio for small format line arrays Large MF/HF horn and Phase Aligned™ LF drivers for exceptional 110° horizontal pattern to 160 Hz KF730 Wizard auto-designs flown arrays Integral lightweight fly hardware of 6061-T6 structural aluminum 16 ohm inputs allow powering 8 KF730s with 2 amplifier channels 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.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
