Personally I've never had good experience running Audyssey after MSO; I always run MSO after Audyssey as it can screw things up. This is especially true if your MSO calibration is across multiple rows, which Audyssey is not capable of accounting for.

I did get the calibrated ACM-1X mic; stock mics are not guaranteed to be well calibrated. My stock mic resulted in a treble boost and bass decrease, which the calibrated mic resolved. One could also just measure the response with UMIK-1/REW and add in any adjustments to the target curve to...

Try adjusting the crossover up/down and playing with subwoofer distance, to smooth out the 80 Hz. If your speakers are ported, there's a phase rotation that happens over the port tune, which can cause cancellation/nulls. Sometimes plugging the ports on the speakers can help smoothen the response...

From the thread, I meant to just point out to the first post that shows the impulse response misalignment. But yeah I think what D+M does is "good enough" for most people, although they did fix the issue in the current 2022 AVRs, so there was some acknowledgement that the calculation was...

I did the .88 multiple thing on my AVR after I uploaded the calibration. I looked up several guides and ran it several times. Most results look the same as I've posted. On your last point, do I simply change the sub distance in my AVR and re-run REW sweeps until it looks better? The frequency...

Few other comments: - I like using Var smoothing, gives a good representation of the whole FR range and leaves bass unsmoothed. - Since you have a pre 2022 AVR, you need to multiply the computed distances by 0.88 to fix the distance bug. Or better yet, take measurements in REW at the MLP with...

Unfortunately no. XT32 receivers have better DSP hardware and filter resolution. MultEQ-X cannot fix that.

I would put as a general rule of thumb: C50 greater than 10 dB over the entire frequency range; perhaps >15 dB for a center channel that carries dialogue. If clarity is too low, add absorption panels to early reflection points (and corner bass traps for bass freqs). This is more to do with room...

I did end up getting a Hypex NC252MP (the Audiophonics one that was reviewed here). Used the ABX switcher and compared it to the Nobsound. Couldn't really hear much difference except for a very slight high frequency roll-off on the Nobsound. Played at fairly loud volumes too. End result was...

Sorry it was a nobsound, not fosi. This one. Yep, I couldn't hear much difference with this rinky dinky amp vs. a Hypex unit. This is running my BMR monitors full range, no subwoofer, at ~75 dB listening level from 11 ft. After this test, I concluded that amps are way overrated. I did hear some...

Umm definitely not. Something’s amiss here.

First position is the MLP center. Other points (and MultEQ-X allows for up to 32 points) can be anywhere you want included in the calibration. The tighter the points are for calibration, the more focused it will be for that listening position. You can have decent response for multiple seats or...

Although it's still cheaper to have it imported from Europe for some of the models, especially with the current exchange rate. Audiophonics NC252MP shipped from France to the US: $500 Buckeye NC252MP: $575

Port distortion is also probably less of an issue when one considers a subwoofer is often present in HT use, typically crossed over around 80 Hz, which is a bit above the port tune frequency for the BMR I think.

Problem with wide dispersion speakers is that in an untreated room, the excess reflections can degrade clarity. This is especially true for a center channel that needs to provide good dialogue clarity. With my BMRs there is a distinct tradeoff between soundstage and clarity when I add/remove my...

AFAIK, EQ systems like Audyssey just try and fit the direct measured sound to a target curve, and ignore reflections. Hence the reasoning for an MRC, to avoid over EQing regions of poor directivity, which can worsen reflections and overall tonality. Maybe other EQ systems can do better than that...

There are lots of modern speakers that have dips in sound power and directivity errors around the crossover. Wouldn't these benefit from some kind of MRC? Examples: Klipsch RP-500M (~1.8 kHz): https://www.spinorama.org/speakers/Klipsch%20RP-500M/ErinsAudioCorner/index_eac.html KEF Q650 (~1...

There isn't a difference, it's the same. Although MultEQ-X by default puts in the 0.87 distance correction factor for pre-2022 Denon/Marantz AVRs, which would come out as a sonic improvement (of course you can manually put this in without MultEQ-X). But MultEQ-X lets you increase the headroom...

The relevant scenario has to do more with your room layout and how many seats you have. MultEQ-X won't be sufficient to optimize bass across multiple seating rows, or for effectively combining different types of subwoofers together, for example. Something like DLBC/MSO is needed to get better...

MultEQ-X will time align different subs (delays), but will still EQ them together. Same as without MultEQ-X. MSO is needed for independent EQ to the subs.
