Eastern Acoustic Works (EAW) has announced the debut of the RSX218, a dual 18-
inch subwoofer that has joined the RADIUS family of loudspeakers. Like other
RADIUS loudspeakers, the RSX218 is designed for both portable and permanent
installation applications.

RADIUS is a comprehensive family of loudspeakers that includes 8-inch and 12-inch
2-way point source loudspeakers available in 2 horn patterns, a double 8-inch
articulated line array, a single 12-inch coaxial stage monitor and single 12-inch, 18-
inch and now dual 18-inch subwoofer models.

“The new RSX218 adds tremendous low-frequency output and punch to the RADIUS
family while still including all of the family’s signature features and benefits,’ explains
Louie King, Marketing and Communications Manager at Eastern Acoustic Works. “The
RADIUS Series has been extremely well received since its debut last year. The addition
of the RSX218 is ideal not only for live sound applications like festivals and clubs but
also for fixed installs in auditoriums, churches and performance venues.’

The powered subwoofer features EAW’s signature acoustical design and technologies
like EAW Focusing and DynO while integrating Dante networking and iOS-based
prediction, control and monitoring via EAWmosiac. The convenient push-button
cardioid operation provides directivity to reduce excess low-frequency energy on
stage. With half space peak output of 141 dB, the RSX218 provides 7dB more output
than the single-18 RSX18 but in a very compact footprint, which translates into less
equipment for larger shows, saving companies on cost and truck space.

The all-wood enclosure with EAW Roadcoat finish is loaded with two high-power 3-inch
voice coil 18-inch woofers powered by 1400W of onboard amplification. The RSX218
combines optimised acoustic, electro-acoustic (transducer) and electronic (DSP)
solutions to provide an extremely efficient system. This efficiency allows it to draw
significantly less current than other subwoofers, allowing smaller AC services to be
used without sacrificing power.

At the heart of the entire RADIUS family, including the RSX218, is the EAWmosaic
iOS-based application. This completely integrated and intuitive platform provides
prediction, control and monitoring at any location in the venue wirelessly. The power
of EAW RADIUS and EAWmosaic deliver spectacular audio results easier and faster
than ever before.

Like the rest of the RADIUS family, the RSX218 features a large, highly-legible
navigation screen that provides on-box access to all RADIUS functions using a simple
turn and push encoder. Dual locking etherCON connectors provide simple daisy-chain
Dante connectivity for single cable audio and communications. There is also an
integrated WAP connection on every RADIUS loudspeaker to provide flexible router
placement options. XLR audio input and thru connections provide an analogue input
option and automatic fail-over redundancy from Dante. And power is delivered via
powerCON inlet and loop connections to simplify cable management.

“The RSX218 is extremely robust and can take a high degree of abuse – even in
extreme bass-heavy situations,’ concludes King. “Advances in acoustic design and
core technologies like DynO have allowed us to push the limits that one would expect
from a compact, dual 18-inch subwoofer. It’s another component of the RADIUS
family that makes it ideal for live and installed sound applications that require flexible
sound reinforcement solutions.’
