Renkus-Heinz SA28‐RD‐WR Weather Resistant (WR), Self‐Powered with RHAON & Dante Redundant, SA1250‐RD

Product Overview

The Renkus-Heinz SA28-RD-WR is a weather-resistant, self-powered dual eight-inch subwoofer with Dante digital audio and network redundancy, engineered for networked commercial installations needing compact, controlled low-frequency support in demanding environments. Its twin SSL8-23 woofers deliver output comparable to a single 12-inch sub in a cabinet roughly two-thirds the volume, and the integrated SA1250-RD amplifier adds RHAON II control, onboard DSP, and AES67-compatible Dante. As a compact networked subwoofer, it complements Renkus-Heinz full-range and steerable loudspeakers in houses of worship, multi-purpose rooms, and covered outdoor spaces.

Product Description

The dual eight-inch SX/SA28 platform provides power and punch equal to most single 12-inch subwoofers in a cabinet that is two-thirds the volume, making it easy to integrate where space is limited. Large ports keep forceful bass free of chuffing or fluttering noise. The built-in SA1250 amplifier is factory-matched to the woofers for optimal damping and multi-band limiting, removing the need for external amplifier racks and long speaker-cable runs. Controlled through RHAON II, the onboard DSP offers eight fully parametric EQ filters, high and low shelf filters, high and low pass filters, and up to 340 ms of delay. The RD model adds Dante digital signal distribution with AES67 compatibility and primary/secondary network redundancy, while the WR option prepares the cabinet and hardware for high-humidity and covered outdoor use. Sixteen M10 Universal Mounting points and an M20 pole adapter support flexible deployment.

Frequently Asked Questions

How does a dual-8 subwoofer compare to a single 12-inch model? The SX/SA28 platform is engineered to deliver output comparable to most single 12-inch subwoofers while occupying roughly two-thirds the cabinet volume, which helps in space-constrained installations.

What does the RD designation include? RD adds Dante digital audio with AES67 compatibility and primary/secondary network redundancy on top of the RHAON II-controlled SA1250 amplifier.

What is the WR option? WR is the weather-resistant treatment that prepares the cabinet and hardware for high-humidity and covered outdoor environments.

Can it integrate with other Renkus-Heinz systems? Yes. It is designed to complement Renkus-Heinz full-range and steerable loudspeakers on a shared network. See the Renkus-Heinz collection.
