Yeah you are defo going to have back problems
are you adams mate from the other day?
like having yer TV next to ya, so you can still watch it while mixing. Are you sitting down?
When I first started I used to do them sitting down, then got a table that was too low for a while. You do at least need the speakers higher up around chest level at least. I bought one of the decks stands and got everything on there and then put my speakers on top of record boxes that sit in front of the stand.
