Overview
The RCF ART 945-A is the top model in the ART 9 series. It uses neodymium transducers throughout: a 15 inch neodymium woofer on a 3.5 inch voice coil and a titanium diaphragm compression driver on a 4 inch voice coil, crossing over at 650 Hz. That bigger driver gives it the most output and the lowest distortion in the range, with up to 135 dB maximum SPL.
It runs a two channel 2100 W peak Class-D amplifier with convection cooling, and RCF's FiRPHASE and Bass Motion Control DSP. The True Resistive Waveguide gives a constant 100 x 60 degree pattern, and the neodymium parts bring the weight down to 22.4 kg, lighter than the ART 935-A despite the bigger driver. PowerCON TRUE1 TOP mains in and out make daisy chaining power simple.
It suits production companies, bands and venues who need a full range 15 inch box that can carry a lot of vocal level, and works equally well as a main or a loud wedge.

Forefront Tip
When you daisy chain mains through the PowerCON TRUE1 link, keep an eye on the total load on that circuit, particularly if subs are on the same run. On loud stages use the Stage preset as a wedge and angle it so the singer sits inside the 60 degree pattern rather than off axis.
