Troubleshooting Audyssey Room Correction: Advanced Techniques for Denon and Marantz AVR Users

If you are into high-end home theater, check out our Display and Audio Calibration Guides to maximize your experience.

When you’ve invested in a high-quality audio system like a Denon AVR or Marantz AVR, ensuring optimal sound performance is essential. Audyssey room correction, which is built into both brands, simplifies calibration. However, room acoustics are highly complex, and Audyssey is not infallible. Users often face issues with sound separation, subwoofer balance, or the clarity of high-frequency sounds.

In this article, we’ll go over common Audyssey troubleshooting tips and explain why certain manual tweaks through MultEQ-X can provide a superior calibration beyond the default settings. If you’ve encountered problems such as disjointed sound fields or harsh-sounding audio, this guide will help resolve those issues.

Fixing a Disjointed Sound Field with Audyssey: Improving Room Correction for Denon and Marantz AVRs

A sound field that feels disjointed—where separate audio channels, such as the front left and front right, don’t blend smoothly—often stems from incorrect speaker distances, levels, or frequency response mismatches. With Audyssey Room Correction, correcting these issues requires more specific manual intervention, especially if the microphone setup process was flawed.

Check Speaker Distances

One common mistake Audyssey makes is miscalculating speaker distances, particularly when the microphone wasn’t perfectly placed during the initial calibration. To fix this:

Prioritize relative distances over absolute ones. Speakers that are too far apart or too close will cause the audio to feel disjointed.

Manually measure the distances using a measuring tape from the listening position.

You can also re-run Audyssey Room Correction ensuring the first mic position is exact and centrally aligned. Correcting speaker placement this way significantly improves imaging.

Manually Calibrate Speaker Levels

Audyssey may misjudge speaker levels, leading to improper balance in the sound field. Use these methods to correct the levels manually:

• Method 1: Use the AVR’s built-in test tones and match levels by ear. Be aware that test tones don’t apply Audyssey filters, so this method is less accurate.
• Method 2: Use a SPL meter to adjust the relative speaker levels and ensure uniformity between channels.

Fine-tuning the volume levels between your speakers can smooth out abrupt transitions in sound movement across channels, ensuring seamless audio reproduction.

Subwoofer Too Weak or Too Hot: Audyssey’s Subwoofer Levels Fix

One of the most significant challenges with Audyssey Room Correction is balancing subwoofer levels. Audyssey calibration sometimes leaves the subwoofer too weak or too overpowering in the mix, especially if mic positioning fails to account for nulls or peaks in the room’s low-frequency response.

Calibrate by Ear Using Familiar Soundtracks

Manual subwoofer calibration by ear can work wonders. Play a movie with intense, deep bass, such as Transformers: Dark of the Moon or Blade Runner 2049:

• Listen to how the bass integrates with the rest of the sound—not just how loud it is, but whether it feels naturally blended with your speakers.

If you use Dynamic EQ, keep it on during the adjustment to prevent inconsistencies. You’ll want your subwoofers to sound powerful without overbearing the rest of the frequency range.

Pro Tip: Gain more precise control over subwoofer performance by adjusting subwoofer levels using MultEQ-X or external measurement tools like REW. The Secrets of Audyssey Pro Guide offers in-depth steps to perfect subwoofer EQ.

Resolving Harsh-Sounding Audio: Working with High Frequencies in Audyssey Room Correction

Even after Audyssey calibration, some users experience harshness—especially in dialogue or high-frequency sounds. This can result when Audyssey applies aggressive correction to certain frequency bands, overcompensating for speaker limitations.

Adjust Speaker Placement

Speaker placement often exacerbates harshness, particularly in the center channel responsible for dialogue. Ensure your speakers are not symmetrically placed between reflective surfaces like walls or floors. Any tilting toward 92-95 degrees can spread reflections away from the listening position.

Midrange Compensation

Another Audyssey feature, midrange compensation, adjusts the critical crossover frequencies between midrange drivers and tweeters. However, Audyssey doesn’t account for varying speaker designs:

• If necessary, disable midrange compensation in the Audyssey App and manually create a 3dB dip using PEQ. For example, if your speaker crossover points are at 400Hz and 2,500Hz, create corresponding dips for those frequencies.

Tip: The Secrets of Audyssey Pro Guide provides detailed steps on using MultEQ-X to smooth the frequency curve and apply customized correction algorithms.

Audyssey vs. Other Room Correction Systems: Choosing the Best for Your Home Theater

While Audyssey offers a compelling solution for Denon AVR and Marantz AVR users, other systems like Dirac Live and Yamaha YPAO present different philosophies around EQ and room correction:

• Dirac Live: Known for its impulse response correction, Dirac can isolate and fix phase shifts in the frequency response, but it requires considerable time and complexity to operate effectively.
• Yamaha YPAO: While effective in basic frequency adjustments, YPAO lacks precision in controlling high-frequency details and above 250Hz tends to apply broader corrections, potentially detracting from natural sound.

Audyssey MultEQ-X strikes a balance, providing user-friendly interfaces for advanced fine-tuning without the high-cost barrier of certain other “premium” solutions like Dirac Live.
