See the review of the Watt/Puppy 6 by Marc Mickelson in
the Dec 2000 Home Audio Equipment Review:

The cabinets of the Series 6 are somewhat larger than that
of the 5.1 and lower series. Since cabinet volume is an
integral part of driver / system design - you can't really
upgrade to the Series 6 drivers without upgrading the
cabinet too - in essence replacing the whole speaker.
So the Series 5.1 is a dead-end; there is no upgrade path
to the Series 6.
