About the Captivator S1
The JTR Captivator S1 is a high-performance sealed subwoofer designed for home theater and audiophile applications. It features a powerful 18-inch driver with an exceptionally high excursion of 33mm Xmax, allowing for extreme deep bass output with very low distortion. The subwoofer is powered by a 2400-watt RMS Class D amplifier that is DSP optimized to deliver smooth frequency response and maximum output with minimal distortion. The driver incorporates a 400-gram aluminum shorting ring to reduce inductance, improving linearity and reducing distortion across the frequency range. The enclosure is constructed from 18mm, 13-ply Baltic birch plywood for strength and resonance control, finished in a matte black lacquer designed to be non-reflective. Connectivity includes RCA and XLR inputs along with a 12-volt trigger. The Captivator S1 is noted for its ability to produce infrasonic frequencies below 20 Hz with high output and accuracy, making it one of the most capable sealed subwoofers in its class. It weighs approximately 117 lbs and measures 21" x 21" x 18" (HxWxD).
