Yi8 loudspeaker

The compact Yi8 line array loudspeaker is designed for use in vertical columns. The 2-way passive design features two 8” drivers in a dipole arrangement and a centrally mounted 1.4” compression driver with a wave transformer. The Yi8 is the installation version of the Y8 loudspeaker and differs only in cabinet construction, finish and mounting hardware. Sophisticated horn geometry combined with the advanced bass-reflex port design delivers full bandwidth capabilities with an extended LF output. These high performance line array modules offer 80° horizontal directivity controlled down to 500 Hz. The mechanical and acoustical design enables vertical arrays of up to twenty four loudspeakers with vertical splay angles from 0° to 14° with a 1° resolution. It can be used in columns of purely Yi8 loudspeakers or combined with Yi12 and/or Yi-SUB cabinets. The loudspeaker cabinet is constructed from marine plywood and has an impact resistant paint finish, whilst Weather Resistant and Special Colour versions are available. The front of the loudspeaker cabinet is protected by a rigid metal grill backed by an acoustically transparent foam. Three point rigging hardware is integrated into the loudspeaker enclosure.

Architectural specifications

Architectural specifications

The 2-way dipolar, passive loudspeaker shall consist of two 8" low frequency drivers with a neodymium magnet assembly and one 1.4" exit neodymium compression driver with a 3" diaphragm mounted to a dedicated wave shaping device and a passive crossover network.
The loudspeaker shall only be operated by a dedicated, compatible controller amplifier.

The cabinet enclosure shall be made from marine plywood with an impact and weather protected PCP (Polyurea Cabinet Protection) finish.
The drivers shall be protected by a rigid metal grill backed by an acoustically transparent foam.
The cabinet shall incorporate a three point rigging system for the assembly of vertical line source arrays of up to 24 cabinets in conjunction with a dedicated flying frame.
The cabinet shall incorporate two M10 threaded inserts on the top and bottom panel for the secure attachment of dedicated mounting brackets.

The connection panel on the back shall be recessed and fitted with two speakon NL4 M sockets and a two pole screw terminal block. A cover plate for protection of the connection panel shall be included.

The loudspeaker shall have a nominal horizontal dispersion angle of 80°. The vertical dispersion angle of the assembled array shall be determined by the geometry of the splay angles between the cabinets, which shall be adjustable in a range of 0° to 14° in 1° increments.

The power handling capacity shall be 400 W RMS and 1600 W peak (10 ms). The frequency response (–5 dB) measured on axis shall be 54 Hz to 19 kHz with a maximum sound pressure of at least 139 dB.

The dimensions (WxHxD) shall not exceed 630 x 257 x 375 mm (24.8" x 10" x 14.8") and shall weigh no more than 20 kg (44 lb).

The loudspeaker shall be the Yi8 by d&b audiotechnik GmbH.
