Have 94db Horn with 7" coil drivers.I tried some SET and it will work but again as mentioned above you often have to discern what they will play with and what they will require to open up and give dynamics's.Fro mine I would say that only a 22 wpc 845 tube SET has enough power or better a 40 watt push pull.And as I have noticed many speakers require more than specs say.B&W's I sold (say the 803 at 8ohm nominal and 90db sens you would see that and think it's an easy drive.But try that speaker with a 80-100 SS or a 45 watt glass amp.It had such a nasty impedance swing on transients a t volume that would be cheating youself with less than 200 watts SS 150 glass better a 300 watt SS and 200 tube amp though they would work with 100 tubes just not open up.And they were speaker that did not get much from tubes as many others.As always few specs can be looked a without taking ion many others to judge what there requirements will be.
