Thanks for your thoughts. The Microvee is the front runner as of now, a Minivee would probably be better but I can not fit a Minivee right now.
Artison make a big point out of the Nano being stable, i.e. not rattling/'walking'.
The form factor of these three subs (Microvee, Nano, CW8) is perfect for my application. Very curious about the Monitor Audio CW8, haven't seen any reviews or measurements on it yet.
