Some KEF R3 Meta measurements with REW - what can be improved

[nygafre]

Don’t worry. You are good. Look at your green curve. If you were to move them “far” away from the walls you loose the room gain effect for the lower frequency and your R3 would lack bass, especially as they don’t have big / many bass drivers.

As said above, to smooth the lower frequencies get at least RoomEQ and if you can a sub or even two.

Ah, yes good point. Seems obvious now when you say it.

Yeah, I will not fiddle too much with my setup. Now I just want to understand more of the why’s and how’s to it’s workings.

I’ve gotten advice on getting sub(s) from Rythmik, Arendal and perhaps SVS. Earlier in June I was looking at SVS; the 1000, 2000 and 3000 models, but they just increased the prices on them in Norway

Thank’s for sharing your knowledge!

Regarding SBIR.. then the huge valley/dip in bass on the red curve is due to the original positioning beeing around one of these frequency nodes/‘quarters’? On this measurement, the front of the speakers were aprox. 47cm from the back wall.

The dip around 150Hz seems to correlate quite well with the SBIR calculations and the positioning, I think.

Either that or a room mode. If you take multiple room measurements across the room and that dip remains fairly consistent, it's likely SBIR. If it drastically changes, it's a room mode.

Thank’s. I just tried the Amroc room mode calculator, which shows room modes around several of my measured dips/peaks.

I’ll try a few measurements later.

If that's both speakers measured as one, it might be a cancellation between the 2 speakers. You'll need to measure them individually to find out.

Ah.. Yes, probably it is the two speakers cancelling as it went away when I moved them further apart. I’ll do some individual measurements of each speaker to verify when I get time.

So far, I’ve not been able to recreate the poor measurement I had in the original position (the red-brown curve), so not sure what happened there. The positioning should be exactly the same. It doesn’t really matter..

Looking to get the S3 stands now, the night stands doesn’t look quite right (but at least they do the job).

Thank’s for all the input!

As a follow up around 1 year later, I'm very happy with the R3 Meta/Powernode-combination. I've since gotten the (rather expensive) S3 stands, and also an SVS SB-1000 non pro to compliment the low end. I also did a dive into implementing room correction/PEQs with Umik-1/REW + EQ APO from my computer with awesome help from @Zolalll. (Results were pretty darn awesome).

I don't particularly like having to run all my playback from my computer in my living room, as I find it quite inconvenient. I also watch a lot of movies via Apple TV 4K and stream music via spotify/apple music, so I am looking to get a more streamlined setup to be able to run EQ on all sources. The Powernode has been great so far, but is not a very flexible solution when you want to add boxes. It is also a bit clunky having to use it as a 'poweramp' in conjunction with EQ APO and volume control from the PC.

What I am looking for/thoughs:
- A device with PEQ filters and bass management. Alternatively something that runs Dirac Live, but I don't really see why I would go that route as enjoy doing the REW/PEQ thing manually.
- Loudness implementation. I currently run it via EQ APO, and it was a revelation to me - similar to the effect of correcting the response.
- Would be nice with something integrated in one single box, but that seems tricky.
- Get something like a MiniDSP Flex HT + Poweramp.. but then I'd be amiss the loudness function?
- DSP Antimode X2/X2D a valid option? As it can be used in conjunction with the Powernodes optical inputs (but still no Loudness equalization).
- And yeah, I hate boxes so less is definitely more.

I got the Powernode really cheap, so I'd hate to spend huge $$ on an upgrade, unless I get all the functionality I want. I think budget could be stretched to the 1500$ mark, but would be awesome if this could be achieved for less.

Appreciate any suggestions

One option with a MiniDSP device, would be to build a set of four target curves, each with a loudness contour built into them so that you could toggle to the appropriate curve for your volume level at the time. I’ve been thinking about doing this, but have not yet, as I generally listen at about the same volume most of the time.

Thank’s that’s definitely an option I could play with. Been actively using the regular tone controls lately, and find that it works rather well to broadly tilt the room curve to preference on the fly, although not as good/neat as the loudness normalization.
