I like that idea but I’d only go down firing for a computer stand subwoofer and this sub seems too big for that. I built one before that sounded pretty good but was very low to the desk and it affected the sound too much. I do have a lot of space behind the monitor tho and I’m sure if I wall mounted it, it would sound good. If not then maybe a small sealed sub would work behind it like a Pioneer TS-A2000LD2 in its recommended sealed enclosure or something more efficient and ported or with prs. I’ll have pics of my old monitor stand sub and the space behind the screen where I can at max fit a 24x12x4 inch enclosure.
