A3, especially if you can only get one sub. I haven’t heard the A3 in a while but I’m pretty sure it goes down to something like 22hz. The A3 will likely sound more coherent as well being a single cabinet rather than stand mounts and integrated sub.
Magico A3 or A1+Sub
Considering purchasing either Magico A3 floorstander or A1 bookshelf + Rel sub (Magico asub gets set up with computer and seems overly complex). A key advantage is these are fully sealed and fairly shallow (10-12 inches) and speakers will need to live about 12 inches max from wall. I have no experience with subs and could only fit one sub if go that way.
Would appreciate any guidance on what would produce best sound quality?
Thanks,
