Salas:
My apologies. It was 8 o'clock on Sunday morning over here, and the fellows you were patiently waiting for an answer from were on the West Coast, three hours behind me. It seemed like you were asking for basic information, so I gave it. Fact is, I do not have a lot of experience with tube amps or even transformer output amps, so I just made the assumption that the output Z was low enough to not to take into account.
If the output Z is high enough to make a difference, then the information I gave you is wrong.
I would only suggest that if indeed your output Z is high enough to make the difference, then if you plan to use an enclosure for your speaker, it would be wise to measure the speaker Qts yourself using that self-same amp. A high output impedance of an amp will change the speaker's Qts value, and therefore it's performance in an enclosure-or even outside an enclosure.

Thanks KW. I always go underdamped with 'tube in mind' speakers. You have a strong point here, that I havent seen it discussed much, though it can make or brake a good tube friendly speaker.

Even my tube amp... or an OTL (more likely to put out 1/2 as much power into 1/2 the load)
What bothers me is that people seem unwilling to separate the speaker reality -- 3 dB more -- from a possible amplifier reality.
Even if you series 2 8 ohm drivers you get 3 dB more with the same power input. Using voltage input is, IMHO, a marketing ploy.

My Decware SET amp prefers a 2 ohm load and has more power there. What I need is a good 2 ohm high efficiency full range driver. Does anyone know of one? These 8 ohm speakers are killing me when I have the house to myself.
There seems to be a trend in car audio toward 2 ohm drivers, or at least dual voice coil 4 ohm drivrs. Most of the drivers seem to be woofers, though there are some mids.
Image dynamics makes a few 2 ohm bass mids, but I cannot find any info on frequency response, etc.
Good luck.
