Looks very good. Almost sold on a Arendal
(just need to save up a little).
I can relate to this. Even though I read (several places) that the R3’s were quite big, they still surprised me.
As a general thought, I think about 40x40cm is visually as large as I would want. I like that the arendal 1S is a bit slimmer, with a width of 31.5.
But sound quality is most important, so the criteria is not too strict.
I have R6c, KEF r3 meta, R3 and ls50 meta for back surrounds with two Arendals 1723 s1.
Best subs I have ever had, they’re very slick not in your face yet they perform superb - down to 10Hz in my room - MLP 3 meters away relatively small room - 16m2.
