I've used for 2 years with a Thule 1.3se IA150B then Nad S300. They are pure marvels of finesse and extraordinary punch. They need a good amp but they are less demanding than the 1.1 or 1.3. These are small bombs that are only slightly surpassed by the sumptuous Special 25 that replaced them in my living room.
The 1.3se are pregnant to listen once in his life to know what libraries (rigid and heavy feet required), surpass all the columns in a room of 15 to 30m2.
