I've been playing around with the R3 meta and Lintons and decided to do up some quick MMM measurements just to get an overall idea of how each speaker is behaving in my space. I wrote some observations as some of the measurements explain some of what I heard, and also raises more questions. Also, I have 2 boys (toddlers), so a speaker that works with the grill on is important to me. I have owned 15+ speakers and pretty much only buy speakers with spins lately. I have to say that to me, these are the best I have come across, but for different reasons.

I've listened for months before doing any measurements, the Lintons definitely sounded warmer, fuller and more forgiving, but had some low mid resonances (maybe the entertainment unit is to blame). This along with the 1khz dip made it less intelligible for movie dialogue relative to the R3 meta. The R3 meta is thinner sounding, but man does it have a way of being ultra clear and detailed without being bright, likely attributed to it's very well controlled directivity and narrower dispersion (lower amplitude sidewall reflections). The difference in dispersion I think is why the Lintons sound bigger, but the R3M have way more space between acoustic elements, and imaging is far more defined and in focus. The R3M do a better job at tricking the brain into thinking sounds are extending past the sides of the speaker, especially when the sounds are higher in frequency. Really great with movie sound effects.

Both speakers sit on a cabinet with just a piece of cork on there, which I think may not be enough, as I find the cabinet really resonates when I have my hand on it. Makes me wonder how much of an effect it's having. I might have to find time to decouple it and remeasure both speakers.

Ignoring the room effects below 600hz, the response is incredible. This is with zero effort (placement, no room treatment, no peq) Kind of astounding. The stuff above 100hz is sbir and floor bounce etc, not 100% sure on the audibility of that mess. The 100hz peak and below is a total disaster but more on that later.

So the above is with the grill on. It doesn't look too bad but I found it audible and was a reason for me to dig out the measurement mic. It didn't sound the same to me.

And here is direct comparison to the Linton. If I saw these measurements, I would have assumed the linton's to be brighter sounding, and less forgiving speaker. I guess the wide mid frequency dip is responsible for it. What I don't understand is how the bass is so different. They're sitting in exactly the same position, woofers at the same height, a few inches different spacing for the port, but the lintons have 10db more bass at 40hz. I mean, it's pretty much a complete bass black hole below 80hz. That doesn't align with their anechoic differences, and there's clearly some room effect going on here I didn't account for. I can't help but think that the entertainment cabinet resonance behaves differently with either speaker resulting in massive cancellations? I know distributed subs will fix some of these issues, and I will eventually get around to building my subs. I just found it interesting.

Other than dispersion, I also wonder if the bass issue is also partly why the the R3M sound thin and don't have that big room filling sound in my space compared to the linton. Male vocals defintely are short an octave. Really doesn't do Johnny Cash or Louie Armstrong justice. Anyone know if a sub helps with male vocals?

Overall the R3Ms are an insanely good speaker, as close to perfect as I have found but I'm probably not going to keep either speaker. If the R3M grill was different, then it would be the one! (As I typed those last couple of sentences I felt like I'm being stupid but I can't quite put my finger on why. I'm sure my wife could point it out though). The Lintons are awesome for music, but I don't love their issue with dialogue for movies. I may play around with some damping material underneath to see if isolating from the cabinet helps, or if it really is just the mid range dip.

This might be helpful:
 
I had both the Lintons and and the R3Ms. Ended up keeping the Lintons. I have 3x LCR and think they do great for movies.
 
Two well designed speakers can sound different. The devil is in the details.
 
the lintons have 10db more bass at 40hz
That's because they just put a louder signal into the room. I wanted to show you a comparision of the spinorama data, but the website seems broken for me.
Anyway, here is the link, maybe it works for you (i submitted a bug report to GitHub):

So lets look at them like this:
Estimated%20In-Room%20Response.webp
Estimated%20In-Room%20Response.jpg


The Lintons put out a lot more SPL below 100Hz, i think that is what you measure.
 
Sorry I haven't got back to this thread, just been really busy with life. I did find some time time to take further measurements that I'll add later, but pretty much any changes (decoupling etc) I made did not make any meaningful difference to the response below 100hz.

@TheBatsEar, I agree that part of the reason for the missing bass is a difference in anechoic output. But it doesn't fully explain the drastic difference between the two speakers in exactly the same position. I included a screenshot to display what I mean. Due to the bass shelf, the R3M is at its worst, 3db lower than the Linton. The in room measurement show a much larger difference, not to mention the lintons also display a much more even bass response below 100hz. It leads me to believe the way both speakers interact with the room are different.

The only things left to explain it is the port placement is different (lintons have two ports that sit lower). I also wonder at what frequencies the enclosure itself acts as a low frequency emitter. Ie does a larger enclosure create a more even in room bass response because it effectively means low frequencies are being emitted from more points in space (conceptually like distributed subs, but obviously not as effective :) )

Do the Lintons sound boomy having them so close to the rear wall?
 
Not at all. It sounds just right. Somehow being 6-8" off the wall results in a 4db rise below 100hz, fits the harman preference curve. Overall it's a fairly big room (10ft ceilings and 500cu ft), so it seems to work well in this scenario.
That's really good to know. I have my eye on these, 800€ seems like a killer deal for exactly what I want - basically the largest good quality "bookshelf" form factor speaker available. No space for towers here.

I'm having this seemingly weird idea of using them as desk speakers - a large one 260cm/7' wide and 90cm /3' deep. Placement further than 30cm/1' from the wall wouldn't be possible. I don't mind a somewhat elevated bass, but ofc it shouldn't be boomy.

Looks like there's no reason this shouldn't work rather well. Time to save up some money, I guess.

They're really big for a desk, and I doubt your ears will be on the listenning axis (which is the tweeter) unless you're at least 7 foot tall

I don't mind the size, desk is easily big enough. Off axis at desk isn't a problem either, because tweeters would be almost ear height, and main "enjoyable listening" position isn't at the desk itself, but the couch further away from it. May have to angle them a bit downwards for that. No problem.

My main concern is or was them being back ported and no more than 30cm from the wall, while being significantly larger and deeper reaching. With my current large (but regular, and also back ported) bookshelf speakers it works fine without any fiddling with port plugging or EQ. Slight bass elevation, but zero muddiness. They start to drop below 50-45Hz anyway.

The Lintons may need some fiddling with plugging and EQ, but if above post is right, that won't be neccessary. Wouldn't hurt me if it was either. This whole room and setup is made of compromises anyway. What I want is getting rid of using the subwoofer. I'm almost there with my current speakers, but not quite. The last bit of deep reach is missing. I'm hoping the Lintons will provide just that.

Edit: here's the situation if you kindly excuse the clutter, shot from couch at ear height, camera angle is misleading in terms of distance (looks too far):

Btw, desk is made from doubled kitchen plates, with backside solidly screwed to the wall. You can walk on it. Never had resonance problems. Works well enough.

Anyway, as said, compromises, not much chance to make big changes. Speaker height works perfectly fine with those books, Lintons would be about 5cm higher (I measured). I'm not looking for the perfect listening setup, that's impossible here. But good enough is good enough.

Of course any input is appreciated. :D

How many of you go back to the warm-toned 'consoles/steregrams' of old? Placing a pair of reasonably extended speakers on a media unit is inevitably going to colour the lower mids downwards for resonances as well as acoustic coupling by appearing to enlarge the baffle I gather (like having chunky flat-faced stands or mindlessly turning a stand mount speaker design into a floor-stander as one company did, without seemingly looking at what extending the baffle downwards actually did - apparently).

You need stands, open frame-ish if possible for the Lintons (they make their own and they're not silly-expensive, at least here in the UK) to get them away from the media unit. if they *must* be sited there, some form of decoupling-stands should be considered I feel, to help stop said unit from resonating with the music.

I'd also suggest that what these speakers are doing *off-axis* is at least as important as the direct on-axis results, as it's the combined effect in-room that's important.

All good fun and well done for posting. Apologies for the lecture as regards speaker stands, but I was a dealer for far too long ;)
 
You need to measure the individual responses of left on its own and right on its own. I suspect the bass issues are caused by cancellation in turn caused by the asymmetrical room placement of the speakers (meaning their low frequency responses in room are likely very different to each other).

Equalization can fix some of this but subwoofers, appropriately placed, and a high pass filter on the mains, plus possibly plugging or partially plugging the ports, will be able to fix the "mess" under 100Hz.
