Hey Greg it's good to see that thing in action! I didn't know you were going to have it as a battler, looks awesome! You have a unique turret & tank I like it
A big speaker box will go a long way in the KV-2, there's lots of room for it... even a regular HL-sized speaker will sound awesome if mounted to something like a sheet of styrene.
