Genelec Subwoofer with 8361A in my room
Not necessarily. Optimized multi-sub setups can gain efficiency.
History of Multi-Sub & Sound Field Management (SFM) for Small Room Acoustics
Solving bass problems in small rooms have historically been done with low frequency absorption (ie. bass traps). This article discusses an alternative/complimentary solution using multi-sub and SFM.

Isn't the bass problems more a norm than an exception in home listening, especially in small rooms. Dirac ART etc. is trying to fix things also by using multiple drivers.
About cables, a bit expensive, but not snakeoil expensive ones:
VOVOX AG, Swiss Manufacturer of high quality Audio Cables

In my current setup I use normal Roland Black ones:

They are cheap.
The problem with the "single listening position" stuff is that you really do need your head in a vice. I easily measure significantly different low bass response depending on sitting straight up and reclining in the same sofa seat.
Yes, in a small room nulls and sums are awfully close. Otherwise you would be really nearfield (studio like setup without studio like environment).

That's not been my experience. I do use a very direct ratio and listen nearfield. We are in the 8631a plus a subwoofer thread.
I am not sure why you're confused, but my setup is obviously 8351Bs and two subwoofers as stated in my signature. The two subwoofers made it much easier to correct the bass for my listening position. Perhaps it is not necessary in your room, but it is objectively incorrect to state that one subwoofer is sufficient for one listening position. As always the only way to know what you need is to measure your own room.That's not been my experience. I do use a very direct ratio and listen nearfield. We are in the 8631a plus a subwoofer thread.

That's not even remotely what I said.

Hello to you all ! It's me once again, just giving a quick review because I received the sub today !
First word to describe is: impressive
Impressive in terms of presence in my room and sound-wise (it's indeed a pretty huge speaker, didn't expected that to look this massive even if I looked at the product's measurements in the first place...reality is irrevocably, let's say, outstanding.
Did my GLM calibration today, multipoint because I listen to it from a couch 3/4m away from the speakers themselves and sometimes my wife listen to music with me so it needed to have a wider calibration and not only the single spot
I've notched up a bit the calibration on the sub slighly across all under 85hz crossover frequency because i'm a bass lover.
Low Shelf in the Sound Profiler, I just tweaked quickly with 100 Hz 3+dB and that's all, I think I should give a try at reducing with the high shelf at 100 Hz instead to see if the low-end is better, I don't know, I will seat a couple more days with the current settings and will let my ears decide for me what's wrong and what's not afterwards. So far they tell me that it's kinda too bright, really at the edge of acceptable but it's because my ears are still used to the previous version of my system with the stereo only I guess. Will see how that evolves on the run.
Still running the loundness feature on the RME, didn't changed that either, works well as it is. Other sources, RME settings and so on haven't change, I just recalibrated the ref lvl on the GLM so that the -20dB on my RME is the normal listening level accross different average music (most of EDM or Kpop music are mastered drastically higher than let's say jazz or classical, but happens that I listen to both of these style in one session so a perfect ref lvl is hard to manage, I did my best to find a sweet spot.
Soundwise, I have to say that it makes everything more clear, even my wife who isn't an audiophile per se (even if she has pretty good ears...) said to me that the differences were huge, and I didn't expected that to be this way, it's just insane how the change in the sound is drastic, it's like I have 5 level of curtains removed from the sound stage compared to without the sub and previous calibration. The voice are bright and distinguishable from any other things while the instruments seats better in the sound stage and the bass is more clear and effortless, fast, punchy... It's a big change that I didn't expected, I mostly imagined it would just give more bass overall, but this...is... on another level.
I attached a pictures of the system, the sub is between the two speakers, it's the only place it can go actually, don't have space somewhere else, or it would be too far away, at the other side of the room which would be hard to manage I would need to move furniture and stuff, so this is pretty cool I guess.
I also look forward to use it when I watch movies with my wife, I'm sure it would be awesome !
Cheers to you
TBD.

Yep always had !
You know, you are on my hate list now
Did you measure, your response? You could be hitting below 20 Hz at the MLP ...
Congratulations...!!

The more I read about everyones experience with adding a sub to a 8361a setup, the more I feel the need to jump in...
However, so far the bass from my 8361a has been exceptional and enough for my listening habits - i do use a vst plugin to reduce bass resonances.
I do wonder if any sub plus Dirac ART would be better than Genelec sub with GLM

Or maybe you would like it better.

Yes, the improvement provided by a good, well-integrated subwoofer is immense.
Enjoy your excellent Genelec solution.
Does using GLM consider both the left and right speakers as bass sources when they are used with a sub? Or does it route all the bass towards the sub?
Specifically, I'm asking whether GLM can do something like Dirac and utilise multiple bass sources to linearize the bass response in a room, or if it "creates" an subwoofer channel with a fixed crossover. Additionally, what happens if you have multiple Genelec subwoofers, does it create one channel per subwoofer? Or does GLM send the same signal to all subwoofers (maybe with delay adjustment).
