Efficient speakers -- What was your journey from A to B to ?
Coherent Audio built on Radian coaxial drivers are great speakers. I listened to their model 18 a couple of times on the Montreal Audio Show. These speakers are really easy to drive. Actually the 300B SET did it very easily and the sound filled a...
