I have a 2.1 also but as you get bigger there are more options. Thanks for the endorsement!I’ve got a Rockboard 4.1 (but just went down to a smaller Duo 2.1 as pictured a few posts above). I’ve been really happy with the Rockboard boards (I’ve got three of them now), easy to route cables and plenty of space underneath for power supplies etc. Happily recommend them!
