Klipsch RSA-500 - Subwoofer Amplifier

Klipsch RSA-500 Subwoofer Amplifier

The Klipsch RSA-500 Subwoofer Amplifier is a custom-install ready powerhouse designed to bring tight, authoritative bass to dedicated home theater and whole-home audio systems. Built around a BASH digital hybrid design, it delivers serious low-frequency control with clean output, flexible connectivity, and installer-friendly operation. With both line-level (LFE) and speaker-level inputs plus unfiltered line outputs for easy system expansion, it integrates smoothly into a wide range of setups—from a single premium subwoofer to dual-subwoofer configurations. Add in an EQ selector (including a preset for the RW-5802), phase switching, variable crossover, and signal-sensing or trigger-based auto power, and the RSA-500 becomes a smart, rack-ready solution for reliable, high-performance bass.

What It’s Good At:

• Delivering high-impact, controlled bass for custom home theater and media rooms
• Powering demanding subwoofer loads with 500W continuous into 4Ω output
• Supporting dual-subwoofer capable installations for smoother, more even bass
• Simplifying integration with LFE/line-level and speaker-level inputs
• Improving match and tuning with EQ selector + phase switch + variable crossover
• Clean rack integration with included rack ears and installer-focused controls

Klipsch RSA-500 Full Q&A:

What is the Klipsch RSA-500 designed to power?

It’s designed to power passive subwoofer systems in custom installations, providing strong continuous output and tuning controls to optimize low-frequency performance.

How much power does the RSA-500 deliver?

It delivers 300W continuous into 8 ohms or 500W continuous into 4 ohms, with an FTC-rated 500W continuous into 4 ohms and up to 1000W dynamic power.

Does it support LFE connections from an AV receiver or processor?

Yes. It includes L/R and LFE line-level RCA inputs for easy integration with home theater receivers and processors.

Can I connect speaker-level signals if I don’t have a subwoofer pre-out?

Yes. The RSA-500 includes L/R high-level speaker binding post inputs, making it compatible with systems that need speaker-level input.

What tuning controls are included for better bass integration?

You get a variable crossover and volume on the front, plus a phase switch (0/180) and EQ selector on the rear for better blending with main speakers and room response.

Does the RSA-500 turn on automatically?

Yes. It includes a selectable signal-sensing auto-on/off mode, and it can also be triggered via a voltage/trigger input for custom control systems.

Can it be used in a rack?

Yes. Rack ears are included, making it straightforward to mount in an equipment rack for clean, professional installs.

Is there an EQ setting for specific Klipsch subwoofers?

Yes. The amplifier includes an EQ preset intended for use with the Klipsch RW-5802 subwoofer.
