The hi-end sound reinforcement system shall hold a 1.4” HF driver loaded by a constant coverage waveguide. It’s exit shall be shared by a low-weight neodymium 12-inch driver loaded by balance-drive horn loading system, powered by a 1200W amplifier.


The maximum peak output of the total system shall be 138dB at 1m.

The syste¬m shall have a 60Hz-20kHz frequency range.

The system shall have a 85 degrees horizontal and 30 degrees vertical coverage angle.

The cabinet shall be constructed of cross grain laminated lightweight multiplex, covered by a protective 2 component polyurethane coating.

The total system weight including amplifiers and audio control shall be 45kg only.

It shall have an IEC XLR-3 audio in and output connector and a powercon in and thru mains connector.


The system shall be a self-powered design holding its own protective audio logic control electronics and amplifiers within the cabinet.
