Renkus-Heinz DR18‐2B‐RN‐WR Weather resistant (WR), Self‐powered, SA2000‐RN Amp ‐ Analog or AES/EBU ‐ RHAON II Network & DSP Control

Product Overview

The Renkus-Heinz DR18-2B-RN-WR is a self-powered dual 18-inch subwoofer engineered for permanent outdoor and high-output commercial installations. A factory weather-resistant enclosure and an integrated SA2000-RN amplifier module make it a fully networked subwoofer that accepts analog or AES/EBU digital signal and is managed over standard Ethernet with RHAON II control and onboard DSP. Its vented, direct-radiating design produces natural, uncolored low frequency down to 32 Hz, making it well suited to performing arts centers, houses of worship, and covered outdoor venues that need consistent sub-bass coverage. As a commercial-grade install subwoofer, it removes the need for an external amplifier and processor while keeping remote monitoring and configuration in the integrator's hands.

Product Description

The DR18-2B-RN-WR pairs two SSL18-7 long-throw 18-inch cone woofers in a heavily braced 13-ply hardwood enclosure finished with a weather-resistant treatment, so the same self-powered dual 18-inch subwoofer can be specified for covered outdoor stages, stadium concourses, and acoustically demanding indoor rooms. The onboard SA2000-RN amplifier module delivers up to 2000 W of Class D power together with native multi-channel DSP, including eight bands of parametric EQ, high- and low-pass filters, shelving, and up to 340 ms of delay, which removes the cost and rack space of an outboard processor. Because the RN module provides analog and AES/EBU digital inputs plus RHAON II control over standard Ethernet, integrators can recall presets, set levels, and read real-time amplifier and driver fault status from a single workstation anywhere on the network.

For commercial deployment, the direct-radiating vented alignment keeps response uncolored from 32 Hz to 120 Hz while the SA2000-RN's multi-band thermal and peak protection guards the woofers during sustained high-SPL program. The cabinet ships with handles, caster options, and M10 universal mounting hardware, supporting both fixed-install rigging and portable use. Paired with Renkus-Heinz point-source and column tops on the same RHAON II network, the DR18-2B-RN-WR forms the low-frequency foundation of a unified, monitored AV system. Integrators standardizing on digital signal distribution should specify this networked subwoofer; sites that only require analog feed can consider the DR18-2B-A-WR analog version, while projects supplying external amplification can review the non-powered DRS18-2B-WR.

Key Features

• Self-powered dual 18-inch design — Two SSL18-7 long-throw woofers in a vented, direct-radiating enclosure deliver high-impact, low-coloration sub-bass for large rooms and outdoor coverage.
• Integrated SA2000-RN amplifier module — An onboard 2000 W Class D amplifier powers the cabinet directly, eliminating external amplifier cost, rack space, and speaker cabling.
• RHAON II networked control — Ethernet-based RHAON II lets integrators configure DSP, recall presets, and monitor amplifier and driver faults remotely across the entire system.
• Analog and AES/EBU inputs — The RN module accepts both analog and AES/EBU digital signal, supporting flexible signal distribution in mixed analog and digital installations.
• Onboard multi-channel DSP — Eight-band parametric EQ, high- and low-pass and shelving filters, and up to 340 ms of delay allow precise system alignment without outboard processing.
• Weather-resistant construction — A factory WR treatment protects the woofers, hardware, and amplifier module for covered outdoor and high-humidity environments.
• Multi-band driver protection — Continuous thermal and peak limiting on every channel safeguards the drivers during sustained high-output program.
• Install and portable mounting — M10 universal mounting points, handles, and caster options support both fixed-install rigging and portable deployment.

Typical Applications

• Auditorium — Provides the low-frequency foundation for full-range reinforcement in performing arts centers and large halls.
• House of worship — Adds controlled, uncolored sub-bass for music and program audio in sanctuaries and worship venues.
• Multi-purpose room — Supports flexible music and AV playback in convertible event and assembly spaces.
• Broadcast studio — Delivers accurate low-frequency extension for studio playback and monitoring in larger production environments.
• Government space — Reinforces speech and program audio in council chambers, civic auditoriums, and large public meeting spaces.

Frequently Asked Questions

What is the difference between the RN and A versions of this subwoofer?
The DR18-2B-RN-WR uses the SA2000-RN amplifier module, which adds AES/EBU digital input plus RHAON II network control and monitoring over Ethernet. The DR18-2B-A-WR uses the analog-only SA2000-A module with the same drivers and onboard DSP, but without networked control or digital input.

Can it be used outdoors?
Yes. The WR designation indicates a factory weather-resistant treatment for the enclosure, hardware, and amplifier module, suited to covered outdoor and high-humidity installations. Provide appropriate mounting, drainage, and protection from direct standing water per the installation guidelines.

Does it require an external amplifier or DSP?
No. The cabinet is self-powered by the integrated SA2000-RN module, which includes the amplifier and multi-channel DSP (parametric EQ, filtering, and up to 340 ms delay), so no outboard amplifier or processor is required.

How does it integrate with an existing AV system?
It accepts analog or AES/EBU signal and connects to RHAON II over standard Ethernet for configuration, preset recall, and fault monitoring. It is designed to combine with Renkus-Heinz point-source and column loudspeakers on the same network for unified system control.

What power does it need?
The SA2000-RN module operates on 100–240 V AC (50/60 Hz) through a powerCON TRUE1 inlet-outlet connector, allowing power looping between adjacent cabinets.

What warranty and support are included?
The subwoofer is covered by the Renkus-Heinz manufacturer warranty. Contact the Creation Networks team for current warranty terms, system design assistance, and post-installation support.
