Rock N Roller Multi Carts! Comparing the R10 and R12 Stealth for many purposes of moving stuff.

Do you think you can fit 2 18" subs side by side on the 12?

[@AndrewYates]

Generally, yes, easily. Unless they are super wide 18" sub cabinets. You could even stack two more on top of each and move 4 at a time.
