New Genelec Main Monitor

Transition seems a little steep there, I would add something in between or at the side (so can be mounted in both directions)

Please do :). Circle equals 15" cone size.

Other than soffit mounting, why not get a 'ones'?
 
In my opinion, the 1235a offers a better sound experience than the 8381a.
If you don't know what the 12xx series speakers sound like, you don't know how high-quality these master series products are. They surpass many high-end passive speakers costing hundreds of thousands of dollars and their amplifiers in terms of sound quality.

The new release on September 30 will have to be really tough if it is going to beat the 1238a in sound quality and sound pressure. That is, if it is a product concept in the same size class.

We have to think out of the box I think.
Since they own the 8381A arrangement at mid-highs already I would tend to believe they will use it at some form.

The mid-tweeter already looks suspiciously the same.

It looks exactly the same
Maybe they're not showing the 4 mid drivers surrounding it on purpose

Just because of the form factor?

I grew up with big woofers, and their dynamic power is hard to beat. To improve on the 8361a, they used a 15"+12" for the W371A. Don't get me wrong, I'd love to have some 8361a's in the living room, but they are too expensive and my wife would refuse. In the music room, I know what I have now is my endgame.

Yeah, it IS hard to put in words, really. I've been gobsmacked since I got the 1039a's in the house, and every day is a new revelation :).

The bits they have publised seemingly fits :).

As far as the 4x mids, I don't think they are needed for this SPL level. The coaxial can do it alone. It also allows for a smoother waveguide, no extra ridges, better directivity. Not to mention the price, weight and complexity.

A triangle has no parallel walls. A tube has the same diameter no matter how you rotate it. Most monitors no longer use purely round straight ports to avoid this port resonance.

The triangle covers 2x surface vs circle. In the 8381a there are no ports since the top box is different shape and higher tuned. To achieve 30Hz in the new speaker, ports are needed, and the ports on 1238a are big, but can't be used with the new waveguide. A triangular port can be bigger and tuned lower than a circular in limited available space. Rear ports don't work with soffit mounting, and a bigger box will not fit existing 1038/1238 soffit holes.

This could have been the new Neumann, but did not happen.
 
I personally like my friend's 1238a model, because in some types of rhythmic music there are occasional bursts of air pressure from the reflex ports, and when listening to it, the air pressure touching your face feels very pleasant from a distance of 3-4 meters, like a summer breeze refreshing an otherwise hot and calm day in a meadow. It's a strange feeling when the bass is big and powerful and then a warm wave also comes pleasantly from the reflex ports, like a lively touch on your sensitive face. However, there are no side noises coming from those reflex ports.


My own 1237a speakers also occasionally produce these bursts of air pressure, but they are slightly weaker than in the 1238a model. This is just general information for others who are not familiar with the special pleasures of Genelec's 12xx master series, i.e., listening to hi-fi/high-end music.

I see there's new ribbed woofer in the videoclip, but couldn't find the right one. Trying to understand what ribbing does for a woofer I found this:

"The speaker cone shape (profile) is a critical factor in the speaker’s sound quality and performance. If the cone is straight-sided (perhaps with concentric reinforcing ribs molded in the cone body), it will be the strongest and more rigid at very low frequencies. Decoupling rings can be molded into the cone body, which look like ribs, but a cross-section of the cone shows that while ribs are composed of added material on the face of the cone, decoupling rings are concentric cone corrugations. These corrugations allow the cone’s effective radiating area to decrease with rising frequency. The off-axis response tends to look better over an extended frequency range with decoupling rings (and curvilinear profile), allowing the speaker system designer the option of using a higher crossover point between the woofer and the tweeter or the midrange." https://audioxpress.com/article/speaker-cones-fabrication-materials-and-performance

Who makes the Genelec woofers?

I wonder why they ditched their smooth woofer
