Do others in your room care? Do you get to sit in the sweet spot?
I've been satisfied with a single 7271 (dual 12") calibrated with GLM. It is right behind were I sit and is flat 50hz and under where I cross it over.
People off to the sides don't care if the bass is a little uneven.
Were you able to get a reasonably flat response in your listening position? I actually don’t care about multiple positions TBH. However, my room is definitely compromised. Typical open plan layout with about 300 sq ft for the living area but open to the kitchen which is another 400 sq ft. One side will have a wall about 6 feet from the monitor. The other would be open for 18 feet.
Also I much prefer the idea of buying a Genelec sub and using GLM. My hope is that I can could buy one 7350 and let GLM calibrate it. Buy another one later and see what it does with stereo subs. Then when they get around to thinking about bass like we are in the 2020s buy 2 more.
In theory 4 7350s would allow for output up to 110dB but while cancelling room modes it would be quite a bit lower.
I would really like Genelec to offer a rough timeline on when they will implement multi sub.
The other wild card is the possible introduction of a W361 or W351.
Also I wonder what happens if you don’t high pass the mains. They will get to about 45Hz. Use those positions plus 2 subs in different positions all running at the same time to attack room modes down to 45Hz with lesser management capability below that frequency.
The W371 gives you options. Where are the options for the mere mortals who can’t drop $18k on a dime? So this is where I feel like I could do better with another system. Then again I don’t want headaches. Going 3rd party is most likely going to amount to buying a headache.
