Audyssey's Next Generation of Room Correction (MultEQ-X)

Are you a current Denon/Marantz AVR Owner and if so what do you think of Audyssey's MultEQ-X?

  • I'm a current AVR owner. $200 price is acceptable. I've already purchased it.

  • I'm a current AVR owner. $200 price is acceptable. I’m willing to spend the money once I learn more.

  • I'm a current AVR owner. $200 price is too high. Anything lower is better.

  • I'm not a current Denon/Marantz AVR owner. $200 price is acceptable.

  • I'm not a current Denon/Marantz AVR owner. $200 price is too high. Anything lower lower is better.

  • I'm a current AVR owner. $200 price is acceptable, but I don't like the restrictive terms. Wont buy.

HI

So far I am very pleased with my purchase. This software is almost necessary to extract the best from Audyssey DRC. MultiEQ-x affords the owner a substantial level of flexibility and convenience, while the mobile App only hints at what can be done with Audyssey. Ratbudyssey was* a third-party effort that could provide similar flexibility. It can still be downloaded, but is no longer maintained by its developer and no one has taken the reins. This MultEQ-X application, takes Audyssey control to another level. I may one day post the before and after REW measurements. in the meantime allow me to be subjective and anecdotic:
I loved the way my system sounded. I use my headphones and now IEM for sound check and .. sanity... The speaker based system sounded good but compared to the Harman EQ-d HE-6SE, somewhat .. "thick". There was a lack of clarity in the upper midrange/ lower treble, the region between 4 and 8 KHz... I accepted it and attributed this thickening to the lowly LSR308; after all these are $500/pair speakers and one shouldn't expect perfection.. On top of that I know the 308 can distort rather heavily in this region... So...
But upon looking at the graphs provided by the software, and verified by REW, it appeared that the subwoofer (I have two but these are seen as one by Audyssey) was having substantial output between 150 Hz and 200 Hz.. The App allowed me to reduce this output by 3 dB and the masking effect disappeared.. I touched nothing else, and now it is a different beast. I applied a peak-filter (actually a notch ) in the area from 150 to 200 Hz.. -3 dB. The effect was clarity in the highs.. REW didn't show any increase in high frequency, of course. There was none, but the masking effect was occulting , for the lack of a better word, the treble.

Thanking again @Reverend Slim for his advice in post 1007.

In our hobby things can get expensive very fast. In this Internet age, we are also used to "free" or at the very least inexpensive applications. REW for example is a formidable application that becomes more powerful as your knowledge of things acoustics increase and it costs nothing, is well maintained, well documented, stable and .. free ... And we all use it and, at time, do not take the time to marvel at what great a gift it it to the community, yes, even to professionals. It may be difficult to ask others to provide their software so generously.. I balked at the price, I, purchased it, reluctantly, grudgingly but would recommend to any owner of compatible AVR. It may transform your audio or HT system for the better. It requires care, knowledge, thus research but the results so far for me are worth the cash outlay.
Sorcerer Apprentice Warning. It also makes it quite easy to mess things up... Fortunately you can save your previous curves and re-load.. re-work on them.

Parting shot: The people at Audyssey need to work on the marketing end. They seem to be on two minds on Audyssey's MultEQ-X , its pricing structure and its licensing protocols. They had a Pro version but it is no longer provided. The MultEQ-X app, still has a strange, unfinished appearance, the manual is heavy on Home Theater not audio systems. They don't go deep to let you know how they approach multiple subwoofers, they don't label it for example a Digital Room Correction, DRC which is what it is ... I believe Audyssey the application and ecosystem deserve better. Their main competitor, Dirac seems to be doing a better job on the Marketing front. I, again , believe Audyssey with the MultiEq-X app, would give Dirac a run for its money... They (Audyssey?/ DEI?) should review their licensing protocols and allow the owner to transfer it at least once to another AVR.

Peace.

P.S Edited for clarification

I remote connected to a friends PC to try and help him tune his system and saw something strange:
Remote connection to another's computer is something that I would pay for to have an experienced person do. Is that something offered by integrators? If not might be a good niche for side revenue.

Also remote teaching for the software cause I'm sure others like me just dont have all the extra spare time required to learn as you go.
 
I've just noticed that on the "Filter Settings" page of Multeq-x, on the "High Frequency EQ Limit" you have the option of "Limit All" or "Limit Measured". Does this mean that you can "Limit Measured" and use PEQ filters full-range or "Limit All" and limit Audyssey measurements and PEQ filters? If it does, this is a promised addition and very useful.
Was this question ever answered?

Not sure but I’ll give it a try. Given they are using FIR filters, I’d imagine that any correction on the low end consumes “taps”

I’m actually in the process of experimenting using the import REW filters. I’m not getting the expected result.

I don’t think those come in as FIR because they don’t know the original measurement (because I deleted/excluded) them
 
Deleting the measurements will still result in FIR filters, but they will work as if you had perfectly flat frequency response and are trying to correct it to match the resulting target curve.

The question is if this new feqture acts like deleting the measurments beyond a certain frequency, which is actually what I requested a while ago to allow manual correction of high frequencies while keeping automatic corrections for low frequencies. Or maybe this does something else we don't really understand.
 
It does work. You can limit measured or limit all. This means you can limit the Audyssey measurements at say 300 Hz and use a PEQ at 4,000Hz.
Thanks. Appreciate the clarification
 
Just bought it to use on my Denon X440H AVR, sucks that it isn't transferrable, but I'm using the AVR only as a pre amplifier anyway to a fully active Genelec system, so I can't see myself upgrading the AVR any time soon. I had a quick go at the L/R and subwoofer using a combination of REW and MultEQ, and this is what I got, really pleased with the result. Also like that any changes to Audyessy can be quickly implemented from the laptop. Hopefully with some work can get rid of that dip around 120hz.

I'm having a blast with it. For this measurement, I had one of my subs off on the left measurement. They overlap (and would if I remeasured) but I was able to get this super flattened with a .7 dB/oct target curve.

The key for me was to measure L+R with MQX, exlude the measurements, make sure no target curve is applied, run the REW measurements against the no-target-curve measurement, then import the target curves to put to the AVR. you'll get exactly what's shown on REW.

Montyliam, I highly suspect you have a misalignment between mains and subs. Try adjusting the subwoofer distance in the AVR to achieve cohesion between the two. You can use either the Alignment tool in REW or the approach as per attached..

Im pretty sure that’s what it is too, the crossover frequency is also 120hz, right at the centre of the dip!

Yep, should smooth out once you get everything aligned

The 120 Hz may be a null due to SBIR. No amount of EQ is going to fix that. Some absorption panels around the speaker may help.

Your response is also flat, which is desired in anechoic or nearfield conditions, but not necessarily in far field. Typical preferred target curves have a downward slope, and also some bass boost. Just something to keep in mind; smooth of course is desired, but flat isn’t necessarily the best sounding target.

No question a target curve is critical (unless montyliam belongs to the .001% of the world’s population that actually prefers a flat response!)

This was just a very quick EQ run of the software, I plan on adding a house curve!
 
It's very easy to check if dip is due to acoustics or due to sub/main alignment - Just measure each separately. If the dip is still there, then it's from acoustics and you can't fix it. If it disappears then it's due to sub/main alignment and you should adjust the subwoofer distance, as suggested, to get best possible summation between mains and subwoofers. Audyssey default subwoofer distance will often provide sub-optimal results in that aspect.

By my own experience though, such dips were rarely due to alignment, but I agree it can be, and is easy enough to check by measurements. It can be reduced significantly by brute force but that may sacrifice too much head room in some cases.
 
With MultEQ-X, is there anyway to disable the filters Audyessy calibrates and just use manual filters generated from REW, I can't figure out how to configure it do this?
