U7 loudspeaker
- U-Series
Compact 2-way passive loudspeaker
The U7 is a high-performance, 2-way loudspeaker providing exceptional directivity control and electroacoustic efficiency. Suitable for both mobile and installation applications, this point-source passive cabinet represents the next generation of d&b technology and innovation. It features dual 8" drivers in a bipole arrangement with a 1.26" compression driver mounted onto a 80° x 55° horn that can be rotated 90° without an extra tool (patent pending). The U7 leverages new industrial design and manufacturing techniques for state-of-the-art horn geometry and advanced bass-reflex ports to deliver full bandwidth and extended LF output (-5 dB @ 55 Hz). The U7 loudspeaker provides 55° vertical directivity control starting from 500 Hz, matched with a horizontal dispersion of 80°.
The cabinet is made of highly durable partially recycled ABS and carries an IP54 rating for dust and weather resistance. The front is protected by a rigid metal grille and an acoustically transparent foam. The back has a handle and M10 threated inserts for attaching d&b rigging hardware designed specifically for either mobile or install uses. The U7 can be both mounted or flown, making it deployable in a variety of ways, especially as a standalone full-range system.
Amplifiers: The U7 is designed for electroacoustic efficiency and works with any standard d&b amplifier. It is optimised for use with 5D amplifiers.
