tdogzthmn, the Mini's are remarkably close to the full Orca's. The primary difference to my ear is the fuller Bass that the full Orca's have, however, while this is a clearly audible difference, if I drop a Dungeness sub into the mix in a room that is roughly 4m x 4m there is very little between a set of Mini's + Dungeness and a set of full Orca's + Dungeness. Both are spectacularly good and perform similarly to my ear when supported by a sub.
