Question about tube friendly speakers...

How many watts is your amp? If it were to be low wattage I'd say the steady 8 ohm load would be better. If the amp were to have 30 watts or greater then I'd have to hear them for demo purposes, without knowing brand names.
Read email I'll send you.
PS you never said which speaker you thouhhght would sound better.

I see you already read the article I was going to email you, from an earlier post.

you should understand that there are several different issues on selecting a tube-friendly speaker:
for me it means that the tube can drive this speaker with no transformer on the output i.e. OTL.
such speaker should have relatively high impedance 10...60Ohm like Coincident to get the tube's best performance.
if a tube or even ss amp has an output transformer than you should select a "transformer-friendly" speaker that basically has relatively flat curve of impedance.
there are also wide-band transformers that have relatively flat and stable responce from 2 upto 16 Ohms(actually used in Macs, VTLs and ARC). i believe that performance of such transformers far superior and safer than any direct-coupling whether tube or ss.
as to efficiency with tube amps you can drive your low efficiency speakers with under-powered tube amp since tube clipping is not destructive to the speaker if it satisfies your room and volume levels.
specifications for the nominal load isn't a factor and for real matching to the amp rather than having impedance curves plotted in front of you. many speakers have a nominal impedance and even minimum impedance specified without specifying the maximum that can also present a tough load and certainly losses of the amp's output power.

Marakanetz is absolutely correct IMO. I ditto everything he says. I have done a ton of research lately about this (qualitative as well as quantitative) since deciding to get a tube setup and your question requires more infomation about the amp to answer correctly. Arthur
