I use the Izombie 2 channel machine driving halogen work lights. The izombie machine is not the cheapest but it is simple to connect. I agree that you need to use a good quality speaker system to really sell it.
I found the screens used for sanding drywall also work very well. It really does not make much sense to go more than 150 grit since you are not usually looking for a polished finish.
