I have used tubed amps on 4-ohm speakers for some time now, so it can be done with satisfactory results. Can't speak for your combination directly, though.
4 ohm taps do Not Necessarliy equate to 4 ohm drive capability. My 27W EL34 monos are more relaxed and xparent on the 8 ohm taps. Course, like Z says, it all depends on the spkr. ymwillv...
Elevick, sorry to hear of your bad experience. I just financed a $2200 3 way speaker designed by a DIYer from Madisound. An absolute mess. 83db!!!, Not one good thing about this speaker, i sold them for $1K. That is funny though, 2.5 ohms! worthless! I'm close to ordering the Thor kit, she's a winner! Trust me the Seas Excel midwoofers are real performers.
Impedance ratings usually mention nominal (worthless?) and minimum impedance loads (valueable). Thiel offers quite a bit of detail re: the specs of their products. A low impedance load does not make a speaker "worthless" it just requires appropriate amplification. If one becomes surprised by true impedance loads after purchase, I think it indicates either a lack of homework prior to purchase or poor dealer support (poor dealer support would be unusual with Thiels).
