The old Duo XD is actually a kind of split into two models. This is due to the development of the new bass drivers and amplifiers. The technique has become so good that as a replacement for the double woofers of the old Duo XD 1 new bass driver is sufficient. Take the new tweeter and midrange driver and with the Duo SD you already have a much better speaker than the old Duo XD.
On the Avantgarde Acoustic website they can tell you a lot more about it. If you want to listen to them, make an appointment with us.
