Renkus-Heinz SA28‐RN‐WR Weather Resistant (WR), Self‐Powered with RHAON, SA1250‐RN

Product Overview

The Renkus-Heinz SA28-RN-WR is a compact self-powered dual 8-inch subwoofer that delivers the output of most single 12-inch subs in roughly two-thirds the cabinet volume. Its factory weather-resistant enclosure and integrated SA1250-RN amplifier module provide onboard DSP and RHAON II network control over standard Ethernet, with analog and AES inputs. The ported design produces tight, low-turbulence bass from 44 Hz, making it an easy-to-integrate install subwoofer for houses of worship, conference centers, and covered outdoor spaces where a discreet footprint matters.

Product Description

The SA28-RN-WR pairs two SSL8-23 8-inch woofers in an ultra-compact 19 mm birch plywood enclosure with large, low-turbulence ports. The integrated SA1250-RN amplifier module delivers 1000 W LF at 8 ohms with optimal woofer damping and factory-tuned multi-band limiting, removing the rack space and speaker cabling of an external amplifier. The RN module provides analog and AES inputs on looping XLR-3 connectors plus RHAON II control and monitoring over a looping Ethernet network, so integrators can configure DSP and recall presets from a Windows workstation.

Onboard DSP includes eight fully parametric EQ filters, high and low shelving, high- and low-pass filters, and up to 340 ms of delay with a 100 Hz active crossover. Sixteen M10 universal mounting points and an M20 pole socket support flown and pole-mounted use, and the weather-resistant treatment suits covered outdoor sites (operating to 140°F, no direct sun). For greater output, step up to the SA112-RN or SA118-RD-WR. Browse the full Renkus-Heinz loudspeaker range for matching tops.

Frequently Asked Questions

Why choose a dual 8-inch sub over a single 12?
The SA28 delivers output comparable to most single 12-inch subwoofers in roughly two-thirds the cabinet volume, making it easier to integrate discreetly while keeping bass tight and low-turbulence.

Can it be installed outdoors?
Yes. The WR treatment suits covered outdoor and high-humidity sites, operating to 140°F with no direct sun exposure. Follow Renkus-Heinz mounting and environmental guidelines.

Does it need an external amplifier or processor?
No. The SA1250-RN amplifier and DSP are built in, so the subwoofer needs only power and a signal feed (analog or AES).

How does it integrate with a networked AV system?
Manage DSP, presets, and monitoring over RHAON II from a Windows workstation. For redundant Dante, specify an RD-equipped model.

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