What is it? An active column speaker array system for portable PA, performance venues and live sound applications. Details Incorporating four 6” high-power woofers and a 2.5” voice coil compression driver loaded from a waveguide on a 100° x 30° constant directivity horn, the NX L24-A is driven by an internal 1.4kW amplifier with DSP control of crossover, equalisation, phase alignment, soft limiting and speaker protection. The birch plywood enclosures may be operated as single columns or in pairs (using single or dual EQ presets) and can be pole mounted, stacked or flown. Frequency response is quoted at 65Hz - 20kHz (-3db) and the enclosures are capable of maximum SPLs of 131dB across 120° horizontal and 30° vertical coverage angles. Enclosures dimensions are 1056mm(H) x 201mm(W) x 274mm(D) and incorporate four M10 and four Quick Lock fittings plus dual side handles. And another thing... Internal processing provides both thermal and RMS protection together with soft limiting.
