Thanks for this - I simply don't have enough room to fit two subs. The DSW ended up cheaper than the DD12+ after adding the analogue card so at the moment will go with the M sub.

After all I have plans to drop the 3200 later for 5200 and having a matching sub for the 3200 would always be better.

So, ordered the system today and hopefully have it before Christmas.
