What Is RP22?

Defined by CEDIA. Delivered by HYPERSUB.

CEDIA/CTA-RP22, the Immersive Audio Design Recommended Practice, is the most rigorous framework for high-end home theater audio performance. Developed by CEDIA and the Consumer Technology Association, RP22 defines

21 technical design parameters that shape immersive audio quality
4 escalating performance levels — from baseline to world-class reference

Of these parameters, four are directly tied to low-frequency system performance — the most critical zone for subwoofers:

Maximum SPL Capability at Low Frequencies
Frequency Response Flatness
Seat-to-Seat Frequency Response Consistency

4. Low-Frequency Extension

These metrics don’t just measure how loud or low a subwoofer can go, but how consistently and cleanly it delivers bass across every seat.

Maximum SPL Capability at Low Frequencies

Maximum SPL (Sound Pressure Level) answers one question: Does it get loud enough?

But high SPL alone isn’t enough. A subwoofer can hit impressive numbers yet sound harsh or unmusical—like a blaring PA speaker. True performance blends:

Sufficient loudness
Exceptional sound quality
Seamless integration into your room

HYPERSUB was engineered to delivery sufficient SPL capability to meet RP22 specifications whilst delivering sound quality that redefines what good bass sounds like, all in a form factor that was designed from the beginning to fit perfectly into any home theater environment.

RP22 defines both minimum and recommended SPL capability levels. The following tables illustrate HYPERSUB performance and outline compliance with the RP22 standards. Note that per RP22 additional SPL capability can be added for bass management and equalization to a target curve if desired.

1. The methodology used is as per section 9 of ANSI/CTA-2010b R-2020 standard, except Maximum Peak Linear SPL is used in line with example calculations in CEDIA/CTA RP-22 section 6.1.4.

2. The F-15 or F-21 system is defined as four (4) F-15 or F-21 subwoofers and one 422D amplifer. The F-24 DUO system is defined as two (2) F-24 DUO subwoofers and one (1) 244D/C amplifier.

3. The F-15 and F-21 are typically high passed at 30-40HZ when used with the F-24 DUO.

Frequency Response Flatness

Frontier systems were engineered to meet RP22 frequency response goals. Hypersub uniquely models each client home theater using advanced numerical techniques to determine in room bass extension, frequency response relative to target curve and seat-to-seat variability for the Hypersub Frontier system specified, whether a simple quad F-15 system or a more complex six F-21 / dual F-24 DUO design. Modeling accuracy derives from accurate test data collected through independent test labs and the 1% performance guarantee, which assures production units vary no more than one percent from the engineering sample. Clients are provided with graphs illustrating compliance with RP22 targets for their selected performance level.

This Isn’t Just a Subwoofer.

It’s the End of Compromise.

From LDLC (Low Distortion Low Compression) engineering to real-world modeling, from RP22-aligned design targets to third-party lab validation—HYPERSUB isn’t built for spec sheets. It’s built for real world home theaters.

We don’t guess.
We don’t cut corners.
We don’t ask for blind trust.

We model it.
We test it.
We prove it—against the highest standards in the industry.

The result? A subwoofer system engineered to meet the demands of CEDIA RP22 Level 3 and 4 performance—something most brands won’t even attempt. This is the new frontier of low-frequency bass reproduction.
