The speaker shall be a sealed-type line array speaker system consisting of 4 individual boxes or “cells” made of polypropylene resin, each measuring 497 mm W × 166 mm H × 274 mm D (19.57” W × 6.5” H × 10.79” D). Each cell shall contain two 5.5” low-frequency cone speakers, symmetrically positioned on either side of the front baffle, and flanked by bass reflex-style form elements at the outer edges. A multi-slotted, high-frequency waveguide manifold shall be located between the low-frequency drivers and be rear-loaded with a 1” high-frequency compression driver. A rust-proof surface-treated steel punched grille shall be mounted to the front baffle of each cell and shall be removable if necessary.
The four cells shall be vertically arranged and mechanically and electronically integrated to operate as a single unit. Mechanical integration shall be accomplished using metal pivot joints between cells and an adjustable, multi-segment steel spine running along the back. The vertical angle between each cell shall be adjustable in 15-degree increments to achieve a total vertical coverage angle between 0 and 45 degrees. An optional extender bracket shall allow vertical angle expansion up to 60 degrees. The horizontal coverage angle shall be fixed at 100 degrees. The system shall be capable of delivering true line-array projection and consistent front-to-back room coverage.
The speaker shall incorporate an internal crossover network dividing the input signal at 1.7 kHz between low-frequency and high-frequency drivers. Electrical connection shall be made via M4 screw terminals located on the rear panel of the middle cell, and the speaker shall have a rated impedance of 8 ohms. The speaker shall produce a sound pressure level of 100 dB with 1 W input measured at 1 m and shall be capable of handling up to 750 W continuous program power.
The frequency response shall be 105 Hz to 20 kHz. The overall dimensions shall be 497 mm W × 664 mm H × 274 mm D (19.57” W × 26.14” H × 10.79” D), and the unit weight shall be 30 kg (66 lbs). The speaker shall provide dust and water protection rated at IPX4 and shall include a rubber-sealed terminal cover and port plugs to prevent water ingress. The speaker shall be finished in a weather-resistant coating and available in black or white. The product shall be identified as the HX-7B-WP (Black) or HX-7W-WP (White).
There shall be several hardware and mounting options for this speaker system:
- HY-CN7B-WP / HY-CN7W-WP: Weather-proof connection brackets for vertically linking additional HX-7 units.
- HY-60DB-WP / HY-60DW-WP: Weather-proof angle adjustment brackets to increase vertical angle to 60°.
- HY-TM7B-WP / HY-TM7W-WP: Weather-proof top-mount rigging brackets with 3-point T-bar for flying or supporting mounting hardware.
- HY-MS7B-WP / HY-MS7W-WP: Weather-proof L-brackets for fixed wall-mounting.
- MT-200: 70V transformer kit with 30W, 60W, 100W, and 200W taps.
- HY-MT7: Transformer mounting bracket for secure installation of MT-200 to the speaker.
