Renkus-Heinz DR18‐2B‐A Self‐powered, SA2000‐A Amp ‐ Analog Input Only

Product Overview

The Renkus-Heinz DR18-2B-A is a self-powered dual 18-inch subwoofer with an analog-input SA2000-A amplifier module, built for high-output commercial installations and portable use. With integrated amplification and onboard DSP in a single cabinet, it is a straightforward, commercial-grade install subwoofer for systems that distribute analog signal and do not require network control. Its vented, direct-radiating design produces natural, uncolored low frequency down to 32 Hz, suiting auditoriums, houses of worship, and performing arts centers. As an analog powered subwoofer, it combines simplified wiring with factory-tuned driver protection.

Product Description

The DR18-2B-A pairs two SSL18-7 long-throw 18-inch cone woofers in a heavily braced 13-ply hardwood enclosure, delivering high-impact sub-bass for demanding indoor rooms and stage use. The onboard SA2000-A amplifier module supplies up to 2000 W of Class D power plus native multi-channel DSP, including parametric EQ, high- and low-pass filtering, shelving, and delay, removing the need for a separate amplifier or processor. The A module is analog-input only: it provides a clean, simplified signal path for installations standardized on analog distribution, without AES/EBU digital input or RHAON II network control.

For commercial deployment, the direct-radiating vented alignment holds response uncolored from 32 Hz to 120 Hz, while 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 for fixed-install and portable use. For covered outdoor or high-humidity sites, specify the weather-resistant DR18-2B-A-WR; for AES/EBU digital input and networked monitoring, choose the DR18-2B-RN-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.
• Integrated SA2000-A amplifier module — An onboard 2000 W Class D amplifier powers the cabinet directly, removing external amplifier cost, rack space, and speaker cabling.
• Analog-input signal path — A simplified analog-only input keeps wiring and commissioning straightforward for systems that do not require digital distribution.
• Onboard multi-channel DSP — Parametric EQ, high- and low-pass and shelving filters, and delay allow system alignment without outboard processing.
• 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.
• Multi-purpose room — Supports flexible music and AV playback in convertible event and assembly spaces.
• Government space — Reinforces speech and program audio in civic auditoriums and large public meeting spaces.

Frequently Asked Questions

What is the difference between this and the WR version?
The DR18-2B-A is the standard-finish model. The DR18-2B-A-WR adds a factory weather-resistant treatment for covered outdoor and high-humidity sites. Both use the analog-only SA2000-A module.

Does it require an external amplifier or DSP?
No. The cabinet is self-powered by the integrated SA2000-A module, which includes the amplifier and onboard DSP, so no outboard amplifier or processor is required for an analog system.

How does it integrate with an existing AV system?
It accepts a standard analog signal feed and combines with other Renkus-Heinz loudspeakers. If you later need digital distribution or networked monitoring, specify the RN or RD amplifier variants.

What power does it need?
The SA2000-A 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.
