When using an OTL(like the tenors) it is more important to choose a speaker with the proper impedance and sensitivity. I am not familiar with the Wilson specs. but if they are 4 ohm and high sensitivity say 94dB@1watt/meter you would probably be OK, but they typically work better with high efficency 8 ohm or higher stable load type speakers. Other tube amps aren't as particular, I use a BAT VK-60 powering a 6 ohm 85dB speaker with out any problems. There are many here who know a lot about OTL's I am sure they will offer there opinions as well. ~Tim
Speaker Impedance, Tenor OTLs, and Watt Puppies
Generally, is it better to match Tenor OTLs, or any low wattage tube amp, with 8 ohm speakers, rather than say, 4 ohm speakers? I do not clearly understand the impedance factor concept, but have been told that 8 ohm speakers are easier to drive, and also that speaker ohm stability is important. Are Watt Puppies a poor match for the Tenors? I know they will sound good, but are the Watt Puppies performance being maximized?
