My first REW measurements(KEF R3 META)

"Room resonances at low frequencies behave as minimum-phase systems
In fact, this is not always the case. One can check this by measuring.
automated "room EQ" or "room correction" programs may or may not be able to do this properly. Many do not."
Agreed. Therefore, it is always interesting to compare in the time domain the normally measured before and after.
 
spectrogram but the problem is I will not be able to interpret this data.
Here was a thread somewhere about wavelet interpretation.
In short, measured in LP, acceptable:

mediocre, rather bad:

and DAC electrical output for reference:

The difference in articulation and clarity and so on can be perceived by ear.

I was quoting Floyd Toole.
 
Is there a solution allowing me to change speakers on the fly with a reasonable cost?
Search for speaker switch box.

Amir reviewed two of these here:

There are less expensive versions without VU meter.
 
Keep in mind that without a way to also switch the volume when switching speakers, to compensate for differences in loudspeaker sensitivity, your A/B test will likely be skewed towards the more sensitive speaker.
 
I still made 0 tries and progress on the EQ front, but I have a (not relevant) update as I found a good deal and ordered a pair of Monitor Audio Silver 500 7G so to try them and replace my R3 Meta if I like them more.
I like these Meta's so much that I find really difficult to imagine how can a speaker sound better. But I had these towers under my radar since a long temp and when I read a new series is released I took my chance to contact some dealers, found an excellent deal and decided to give them a try.

Hi @kolestonin I saw https://www.audiosciencereview.com/forum/index.php?threads/fs-eu-kef-r3-meta-pair.57986/, just curious if you ended up liking the Monitor Audio's more in your room?
 
Hello,

I am still in my discovering period with them but my answer to your question is definitely yes.
I think I miss the narrow dispersion of my META's as I notice side window reflections are more evident now. My thick curtains do the job easily though. What is also missing, but I don't necessarily miss, is their neutrality.
Monitor Audio's have better bass, an impressive mid-range-high blend, and they do everything better. My first impression was they were a bit bright but it seems it is not the case. I was maybe influenced with some users and reviewers opinions saying they are on the bright side, and I was also coming from the META's which are definitely not bright(I had the simple R3's as well which were a bit pronounced). But most importantly, what was causing this bright effect were my sub. Which I struggle to integrate it seems as everything sounds better with them out of the chain. And speakers are not bright, but not so neutral(as the META's) and definitely more engaging.

It is also worth mentioning, that others members of the household found the difference impressive in favour of the Monitor Audio's. But I know better than them what my META's could do and how to appreciate their value. It is a clear win but not a hands down one.

I plan to share more thoughts and eventually some measurements on the Monitor Audio Silver 500G dedicated thread.
For the moment you can give a look at some firs feedback on below:

 
Thanks for responding and appreciate hearing your thoughts, hope you enjoy the new speakers!

RE: degradation when using with subwoofers, your current setup has the subs using a 90Hz low-pass filter but no high-pass filter on the mains? If so more bass from the mains (assuming MA Silver 500 has deeper bass extension and doesn't have the bass shelf of the R3 Metas) could be making the lack of proper subwoofer integration an even bigger issue. So I'd agree with earlier comments in this thread about adding bass-management DSP to the playback chain.

Best option I'm aware of was already discussed in this thread, MiniDSP Flex replacing the Topping E30+Pre90. Another alternative could be https://www.audiosciencereview.com/forum/index.php?threads/wiim-ultra-streamer-preamp-review.57342/, which would give a proper LPF+HPF crossover and 10-band PEQ. Not as powerful as the MiniDSP Flex and no option for Dirac to do automated room correction (Wiim has their own basic one but it's not going to be comparable), but good DAC, trigger out (though your Boxem amp may have auto on/off already?), more input/streaming options if that's of any value to you, and a lower price point.
