I attended a Genelec immersive seminar yesterday. A generous and professional hosting in a large convention building. A half-day was dedicated to the theory behind immersive sound; the second half to mixing in object-oriented environment and auditioning tracks in a variety of genre.
It was my first exposure to immersive music, and I was stunned. Yes, there was a novelty effect, but there was more to it. The way the music engulfed me and shifted around was mesmerizing. Immersive may be a niche market for now, but, oh boy, it’s sure worth pursuing.
The loudspeakers were high-end—S360 L/C/R; 8351B field level; 8341A top level; and 7380 x 3. There were a few deficiencies: the hall was huge and not treated; the layout was too spread out for 7.1.4 (IMO); and the subs were placed far from any wall. Still, the sound quality shined through.
Having so many Genelec personal around, I couldn’t restrain myself and picked their brains on quite a few issues. Here are a few tidbits I thought this community would be interested in:
----
Having placed the 371+83x1 and 8381 behind a screen, Genelec asked listeners to pick the best sounding system. Without fail and with ease, all bar none chose the 8381. Apparently, it’s quite a jump.
----
For stereophonic system, the 8381 won’t benefit from a sub, and they recommend against it. In a damped room, the One Mains can go down to 17hz.
----
1236 vs 8381 in distances over 2m: The One has a superior vertical directivity, and that makes a big difference. The active bass management should yield results as good as embedding the mains—or at least in most cases. In some difficult rooms, an embedded 1236 would serve better. And of course, the 1236 boasts higher SPL.
----
One gentleman related to me that they sell a lot of 8361, but the optimal mains to match with the W371 are actually 8351B and 8341A. I’d heard that rumor before.
----
In an immersive setup with multiple subs, depending on the dimensions of the layout, it might be advantageous to assign certain monitors to each sub. Moreover, it may make sense to mount some subs higher up, to better localize them with the tops. I found the notion intriguing.
----
I was hoping Genelec would incorporate an HDMI port on their 9310B and offer a seamless digital path from TV to speakers. That is not to be, as Genelec won’t develop it due to 3rd party restrictions and poor eARC implementation. They feel that Dante is the way to go, since studios are already committed to it. Analog it is for households.
Back to the immersive experience: a 7.1.4 made of 8331 and 7380 might be more enjoyable than the best mains Genelec has to offer in 2.1 setup. Just a thought…
