The one in Newcastle has the Sub and Shaker - it does sound good, clear and bassie, with the sub making a difference as I heard the other one at AMD without a sub though don't get me wrong this sounds very impressive as well. It stays clear when cranked but doubt it matches to a good home theatre system (sorry Cavey) as I have a Bose system connected to a NAD amp and it cranks.
But for all those getting a AC/DC Pro or better you will be stoked as for a pinball it's loud and clear.
