If I am reading this correctly, neither 8351 or 8361 is ideal for listening over 3 meters away because the direct sound would be overpowered by reflections. Or is that not an issue because the directivity is so good?
I spoke with Genelec here in the USA regarding my requirements. I sit 10 feet away from the speakers and asked whether the S360 would be preferred over the 8361 given the listening distance. I was told with no uncertainly to get the 8361.

That's a no brainer to me then, that's ballpark $3000 less for the 420s which are excellent.
You must add external room correction to it, which should decrease that difference. I'd still take the 8361A, personally, but I'd hesitate seriously if the KH430 got the whole DSP package (phase correction, factory calibration, MA-1 support) and more amplifier power (its woofer gets 330W instead of 700W for the 8361A while playing a few Hz lower) while keeping the same price. Would still get the coaxial, probably.

A MiniDSP SHD Studio or similar is far less than that price gap. But, also - 330w for one driver is really about the same ballpark as 700W for 2 drivers.

??? The combined surface (thus the excursion requirement) is similar, so I don't see why it would be similar. Unless sensitivity is really much lower on the Genelec, which is possible.

Power per driver, I mean. Each of those racetrack woofers in the Genelecs is seeing 50% of that amplifier's power. Of course the surface area comes into account here, but realistically I think 330w is enough power even with that kind of extension to have the amplifier not be the limitation.

I really don't know. I mean, it's not like Genelec to put twice as needed for fun. So I really wonder if sensitivity is the reason.
A reason could be that Neumann is limited by using a boatload of chipamps (cf this post) instead of a discrete and possibly more modern design. Heat dissipation of class AB could also be a limit, even though the KH420A seem to have a quite beefy and well designed convection heatsink.

So basically the 2 8361A racetrack woofers area= 10 inch "normal" woofer?

Code:
Neumann spec: 265 mm (10") woofer
Genelec spec: Dual 263 x 137 mm (103/8 x 53/8 in) obround cones

area = 263 * 137 * 2 = 72062 mm²
radius = sqrt(area / pi) = 151.5 mm
diameter = radius * 2 = 302.9 mm = 11.9"
Should be near even when shaving the corners to transform Genelec's spec's rectangles into racetracks.

What I find crazy is how much more the 61 weighs more than it's predecessors.

Maybe the larger you make it then the thicker you have to make it too (walls), along with the added weight from the extra dimensions too - in order to keep the same "stiffness".

As I noted in an earlier post on this thread, I have been listening to the 8361s in my room for about a week now. I am definitely not keeping them. Aslo, as noted earlier, I listen primarily to classical music. I am an amateur musician having played in orchestras and chamber groups and also luckily part of a musical family. We have violins, cellos and a piano in the house. I have attended classical music concerts on a regular basis since I was a child. I understand that for many of you here, this is irrelevant, subjective information that gets in the way of appreciating the measurements. I read In this thread somewhere that old people will reject accurate speakers because we (I am in my 50s) are so used to colored sound that neutrality will sound bad. I reject that condescending view. I have listened to and played classical music for decades. I know what a violin sounds like. I have also listened to classical recordings since I was a child. I do not consider myself an audiophile, but have always recognized the importance of audio equipment. I do not need to be told that most classical recordings are poorly engineered. As you might imagine, I know what records I think are beautiful and realistic.

The 8361 before correction with glm was bright, harsh, and synthetic. The sound of a violin is, in my view, one of the most beautiful sounds. I found violins and pianos on the 8361 to actually sound ugly and irritating. Like listening to a child practice violin in a small room. After correction, the bass was definitely improved, but the treble was even worse. So, I knocked down the treble levels. This helped, but still the instruments sounded synthetic and unmusical. It may have something to do with the waveguide dispersion, but I really have no idea. i can say with a fair bit of confidence that many if, not most serious acoustic music listeners, will have trouble with this speaker. The bass is, to be fair, very nice. Cellos and lower notes on pianos were fine. The very low notes were excellent, but from upper mid range on up, I think the speakers are not accurate reproducers of the sound of acoustic instruments to anyrhing approaching the level of bbc style monitors or quad esl speakers.

Anyway, I understand that many here will reject my dislike of the speaker as mere subjectivism. I think there is much confusion about what science is floating around our culture. Observation and description are as important to understanding as measurement and engineering. Robust measurements of speakers are undoubtedly important and even necessary for judging speakers, but it is not sufficient. For too long mainstream audio magazines have relied only on listener reaction. They have pushed snake oil that ASR rightly rejects. Engineering is obviously essential, but it must be combined careful listening by people with knowledge of music. I see very little of that at ASR. How often are pianos, cellos or clarinets mentioned here? As I understand it, Amir’s “subjective” review was based only on listening to one speaker. If that is so, then I think he would be better off just giving us the measurements without trying to tell us if the speaker is good. Does anyone here even listen to classical music or attend classical concerts on a regular basis? Ok, enough, I know. I just wanted to record my observations about my experience with these speakers with classical music. in Sum, I found the speakers to be somewhat shrill and artificial sounding; strings didn’t sound like they do in real life, even on recordings that do much better on other speakers. They will play very, very loud and the bass is great. “There are more things on heaven and earth, Horatio, than are dreamt of in your philosophy”.

Yes, and I’m reasonably certain that the difference you’re describing is due to the narrower beam width of the mids/treble. You’ll probably find yourself preferring wider beam speakers like Revel for stereo reproduction of acoustic and other real instrument performances, as do I.

However, you can reproduce similar acoustic realism with Genelecs, you just need a multichannel configuration with stereo upmixing — which of course is not for everyone. But when you do and you toggle back and forth between fronts only and multichannel upmixing, it becomes extremely obvious that what you describe is due to different dispersion patterns.

it is obviously true that speakers reproduce recordings. Some recordings sound like real music than others. I have spent decades sorting through which recordings I think those are. I prefer recordings that sound like music played on actual instruments In real space. once One has found some of those recordings, that seems like a fair way to judge a speaker. Otherwise, we are left with no standard at all, and little pleasure, which, after all is why we listen to music.

‘Fine measuring loudspeakers simply reproduce the file more accurately, of course you may not enjoy that.“

I listen to music all the time. I like the sound of real instruments well played. Many recordings are good approximations of that. Most are not It is easy to condescend and repeat empty truisms, but the 8361 in my room is not a speaker that can convey that sound or be listened to with pleasure by a knowledgeable music lover. Shouldnt a good recording of a clarinet sound like a clarinet on a good pair of speakers? Publish the measurements, by all means. They are valuable information. But maybe at least find someone with mucosal knowledge to see if the speakers are musical.
