Cute, but once you've got 2 DDC 3.2's in series, the third one really doesn't do much for your performance. My own testing saw a degree improvement... maybe. And this one doesn't conveniently fit into a 5 1/4" bay like the dual-version does. If you were hard-core about silence, perhaps using 3.1's might be useful? In a very limited, expensive sort of way?
