The Model 1 isn't the weak point. I've used the Totem Model 1 signatures and they will rise to the occasion depending on what you use to drive it. Just before I retired it to a home theatre system, they were sounding pretty amazing through a AR/BAT/Krell system. The Dynaudio mid/bass driver is difficult with impedance listed at 4ohms. But in fact is goes down as low as 3.6 in the upper bass. So in order to get more bass out of the speaker, you need to look at high current amps that are able to drive the speaker to let it do it's stuff. When I upgraded from a Classe CA100 to a Krell KSA200s the perceived bass doubled.
Or you can move it around the room to see if it's a room node issue.
