What is the AUDAC MBK302S/B ceiling flying system?
The AUDAC MBK302S/B is a ceiling flying system designed to suspend one FX3.15 15" 3-way cabinet and one FX1.18 18" subwoofer as a single flown stack. It lets integrators hang the FX top and bass cabinets from a ceiling or other structural point while aiming the loudspeakers at the required angle. The black kit is built for permanent installation of high-output FX systems in venues where floor space or sightlines rule out ground stacking.
How does the AUDAC MBK302S/B ceiling flying system work?

The MBK302S/B is a complete bracket set rather than a single frame. It contains one MBK310/B fly frame for FX series loudspeakers, one MBK315-01/B side board set for the FX3.15 (2 pcs), one MBK318-01/B side board set for the FX1.18 (2 pcs), one MBK318-02/B rear connection board for the FX1.18, one MBK320-01/B connection board set with a 20° to 60° angle plate (2 pcs) and one MBK302S-SS screw set. The side boards attach to each cabinet, the connection boards join the subwoofer and top cabinet, and the angle plates set the downward tilt of the FX3.15 so coverage lands on the audience area. Steel safety wires (Ø 8 mm, 3250 mm and 3150 mm) and a 1.5-ton bow shackle are not included because of local legislation, so source certified suspension hardware locally. The complete kit weighs 100.97 lb, which must be added to the cabinet weights when calculating the load on the rigging point. Pair the flown FX stack with SMQ500 or SMQ750 WaveDynamics DSP amplifiers for crossover and driver protection. AUDAC also lists an MBK302SI/B version that is technically identical and differs only in improved packaging.
What are the key features of the AUDAC MBK302S/B ceiling flying system?
- Purpose-built for the FX series — the kit is designed specifically to fly one FX3.15 top cabinet together with one FX1.18 subwoofer.
- Adjustable aiming — the MBK320-01/B angle plates allow the top cabinet to be tilted between 20° and 60°.
- Complete bracket set — fly frame, side boards, rear connection board, angle plates and a dedicated screw set ship together.
- Ceiling or structural mounting — the stack can be flown from a ceiling or other suitable position instead of being ground stacked.
- Black finish — the black hardware matches the black FX cabinets for a discreet flown installation.
- Local safety hardware — safety wires and shackles are excluded so installers can fit locally certified suspension components.
