Architectural Specifications
The loudspeaker is an active three-way bi-amped system. It features a high power 15" (380 mm) isometric triangular horn loaded low frequency (LF) transducer. The mid-high frequency section includes a two-way design with an 8" (200 mm) isometric triangular horn loaded mid-high frequency (MHF) transducer and a 1.5" (38.1 mm) diameter exit high frequency (HF) compression driver mounted on a waveguide.
Both the LF and MHF transducers are housed in separate, independent moulded fibreglass composite cabinets with a smooth cellulose finish, available in any RAL colour. The transducers are built on cast aluminium frames with treated paper cones. The LF voice coil is 63.5 mm (4") and the MHF voice coil is 50.8 mm (2"), both wound with copper wires on high-quality formers for robust power handling and long-term reliability. The HF transducer utilizes a high-precision waveguide with a 200 mm (8") baffle to ensure controlled pattern and low distortion.
Performance specifications include a usable on-axis bandwidth of 120 Hz to 20 kHz (±3 dB). The average directivity pattern is 60° vertical and 90° horizontal (-6 dB down from on-axis level) from 1 kHz to 12 kHz. Maximum SPL is 138 dB peak measured at 1 meter using IEC268-5 pink noise. Crossover points are set at 500 Hz and 1.4 kHz using 3rd order filters (18 dB per octave). The system is powered by a dedicated amplification module with DSP management.
Connections are made via two Neutrik speakON™ NL4 connectors (one for input, one for loop-out). The enclosures are secured to a powder-coated steel frame using at least four M8 bolts per horn. This frame ensures correct acoustic alignment for constant directivity across the dispersion range and includes mounting holes for U bracket fixtures for ceiling, wall, and ground stack mounting.
The external dimensions of the enclosures and frame are 810 mm (width) x 515 mm (height) x 720 mm (depth) (31.9″ x 20.3″ x 28.3"). The total weight is 47.1 kg (103.8 lbs). The loudspeaker model is the Void Acoustics Tri Motion.
