Sound Projects - SPX-4

The sound reinforcement system shall hold a 1.4” HF driver on a horn with a horizontal dispersion of 85 degrees and a vertical dispersion of 30 degrees and a low-weight neodymium 12-inch driver on a balance-drive horn loading system, powered by a 1200W amplifier. The maximum peak output of the total system shall be 138dB at 1m. The system 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.
