Feedback of my installation after a few months now.
It consists in 3 8340’s, 2 8330’s and a 7370.
The room is 5m x5m and ceiling is at 2m20 height.
It can totally deliver an extremely loud home cinema experience. 7370 mandatory though, only way to get these powerful bass movies require.
We sit 3m 3m50 from the projector screen.
Plus, listening to music in stereo mode is probably the best experience I had with any system, you can listen forever to the system without any fatigue even at high volume.
Spatialisation with glm is delightful, though, the sweet spot is not super wide, I could probably perform a multiple point measurement but got lazy on this one.
Another nice feat is the ability to switch from music in the digital input to AV in the analog input.
I am using a chromecast linked to an optical to aes ebu converter and it works like a charm. Very convenient to turn the 2.1 set up into a smart appliance with the chromecast.
For anyone interested, you need to set up your genelec in automatic mode in glm.
