Overview
<p>The ISORAY18S is a flyable line source subwoofer system engineered to deliver exceptional flexibility and high-output low-frequency performance in professional sound reinforcement applications. Its unique bi-directional rigging capability allows for seamless integration in both vertical and horizontal configurations, adapting perfectly to any venue's acoustic demands.
</p><p>At the heart of the system is a premium 18-inch CELTO 18EXN1200-8 transducer, featuring a 4-inch (100 mm) long-throw voice coil and a die-cast aluminum chassis. Delivering 1200 W RMS (4800 W Peak) power handling, it achieves a maximum SPL of 134 dB Peak and a frequency response spanning from 33 Hz to 100 Hz. The system operates exclusively in active mode, ensuring precise control and optimal acoustic coupling.</p><p>The enclosure is constructed from heavily braced, marine-grade Baltic birch plywood with tongue-and-groove joints, finished in a touring-grade rubberized PolyUrea coating. Front-to-back connectivity is simplified via genuine Neutrik Speakon NL4MP connectors, including a front-mounted input with a dedicated switch to facilitate clean cardioid arrays. Fully integrated, cable-free rigging hardware and an M20 pole mount socket provide secure, rapid deployment for both flown and ground-stacked configurations.</p>
