That is correct.  The old room station speakers are not compatible with the
new DCM3-4 system.

It's just the way they designed the new system.  A cynical person might be
inclined to believe they just wanted to sell more new stations.  I spoke to
my M&S rep and he seems to think that's the reason, too.  If you need help
configuring a setup, feel free to contact me.  I carry M&S though I haven't
put all of the components online yet.
