The ID3.115-66 is a two-way, full range loudspeaker, designed specifically for permanent installations. It is comprised of the McCauley 77105 15” cone driver and a 3.0” diaphragm compression driver mounted to a rotatable 60° x 60° waveguide.

The 77105 features a large 4” aluminum voice coil to improve power handling, an FEA optimized, field serviceable ferrite magnet structure, and a lightweight hybrid paper composite cone. The new cone body balances high stiffness, to keep breakup modes above the crossover frequency, with the internal damping that is inherent to paper cone loudspeakers.

The coupling of the cone driver and high frequency waveguide has been specially engineered to produce a rich and fully balanced sound from 50 Hz to 18 kHz. The ID3.115-66 is available in either a bi-amplified or passive configuration and features a versatile rigging system.

Mounting locations are distributed across 5 surfaces of the enclosure. Omni-mount™ compatible locations are available on 4 sides of the enclosure, while an additional 14 reinforced 3/8-16 threaded locations are available for other mounting options. iDESIGN iDB™ Series array frames are available to facilitate assembly and suspension of multiple modules as a single cluster. iDESIGN iDB™ Series U-bracket hardware is also available for single unit wall and ceiling mount installation.

The enclosure is constructed of 18mm 13-ply void-free birch plywood and is coated with a weather and wear resistant ProCoat™ polyurea hybrid finish. Loudspeaker components are protected by a flush mounted, wrap-around perforated steel grill lined with acoustically transparent foam. The grill and rigging components are weather protected with a heat cured epoxy powder coat finish.
