EAW RSX218 - 1400W 2 x 18-inch Powered Subwoofer with 3-inch Voice Coil in Black Finish

The EAW RSX218 is a powerful and versatile 1400W powered subwoofer, equipped with dual 18-inch drivers, designed to meet the demanding requirements of rental firms, system integrators, and production applications. The RSX218 combines EAW's signature acoustical design with intelligent features that streamline setup and provide maximum sonic performance with minimal setup time. Ideal for applications requiring robust low-frequency output and precise control, the RSX218 integrates advanced DSP processing, including Focusing and DynO technologies, to deliver pristine impulse response and deep, controlled bass at all output levels. Its push-button cardioid operation is designed to provide directivity, helping to minimize excess low-frequency energy on stage and improving the overall listening experience in both large and small venues.

The RSX218 features dual 18-inch low-frequency transducers with a 3-inch voice coil, allowing the subwoofer to handle high output levels with remarkable efficiency and clarity. The 1400W maximum power output ensures that the RSX218 can deliver powerful, deep bass in even the most demanding environments. Ultra-wide ports are incorporated into the design to drastically reduce low-frequency turbulence, delivering smoother, more controlled bass response without distortion, even at peak volumes. With an operating range from 27 Hz to 125 Hz, the RSX218 covers the full spectrum of low-end frequencies, ensuring accurate and powerful sub-bass reproduction for professional sound applications.

With full Dante integration, the RSX218 offers seamless digital audio distribution and networked control via Ethernet, allowing for easy integration into modern sound systems. The subwoofer includes two Neutrikx etherCON RJ-45 connectors for Ethernet/Dante communication, providing reliable data transmission for large-scale sound installations. Analog redundancy is built-in, ensuring reliability and continuity in the signal path. Additionally, the subwoofer supports XLRF input, with electronically balanced wiring to maintain signal integrity and clarity. The RSX218 also features Neutrik PowerConx for AC mains input, ensuring secure and reliable power connections with an input voltage range of 100V to 240V and a frequency range of 50Hz to 60Hz, making it suitable for use worldwide.

In terms of performance, the RSX218 achieves a calculated peak SPL of 135 dB (whole space SPL with a 12 dB crest factor), providing deep, impactful bass output for large venues and demanding applications. Its nominal beamwidth of 360° horizontal and 360° vertical ensures even bass coverage across the audience area, ideal for installations requiring consistent low-frequency response. The RSX218's DSP-controlled amplification, with integral limiting, protects the drivers from overdriving, ensuring long-term reliability and consistent performance over time.

The RSX218 is also designed for ease of use and system optimization, with the EAWmosaic iOS app offering system prediction, control, and monitoring from anywhere in the venue. This comprehensive application allows for room design, system simulation, and real-time adjustments, making it easier than ever to optimize the performance of the RSX218 in a variety of acoustic environments. The user-friendly push-button rotary encoder and LCD screen on the amplifier panel provide intuitive control and monitoring of the system's settings, and the logo LED is customizable for visual feedback during operation.

The RSX218 features a rugged build, designed for durability in demanding environments, and weighs 153 lbs with compact dimensions of 20.6 x 44.0 x 31.1 inches, ensuring it can handle the rigors of transport and installation without compromising on performance. The subwoofer's sleek black finish and high-quality construction make it a visually appealing addition to any professional audio setup.
