Tube amps and speaker ohms

Raul, I am not going to argue with you, mainly because I do not quite understand your comment. I think this is mostly due to the fact that neither you nor I have English as our mother tongue.

Transistor amplifier have lower output impedances and are therefore much more suitable for the majority (99%) of modern speakers. They can easily maintain a constant voltage against a speaker load where a tube amp will struggle. In the perfect world, vacuum tube amplifier should have speakers rated at 64ohm/128ohm and higher to do so. Hopefully one day I can get somebody to build me speakers like that to fully optimize my tube amplifiers.

I also believe almost all vacuum tube amplifiers are used against speakers where they do not perform well – Bartokfan is a good example of this.

However, you are incorrect if you say vacuum tube amplifiers cannot maintain a constant voltage against a loudspeaker. It is simply a more difficult to achieve.

You are welcome to disagree and I know and respect your view on transistor vs. vacuum tube.

Ok, here is a question that may show my ignorance of this subject but, I will ask anyway. I have a TAD-60 AMP (60 WPC ultralinear).. It has 8 and 4 ohm terminals. I am running Vandersteen 2CE signatures which are rated at 7 ohms nominal and 4 ohms minimum. I am currently using the 8 ohm terminals in my set up. Would I be better off using the 4 ohm terminals? If so, then why. If not then why not.
Thanks,

Eagleman,

A simplified response -

If bass control seems to be a problem for you when you use the 8 ohm taps use the 4 ohm taps. If you use the 4ohm taps and the highs are not smooth use the 8 ohm taps.

Simply said, use the taps which sound best to you. My guess is that if you are listening at moderate levels the 8 ohm taps might sound best.

Eagleman, feel free to ask w/o feeling you will get criticized. I get snides and insults due to lack of tech knowledge, snotty attitude, "mister-know-it-all", negativity, closed minded-ness. So as long as you don't follow me, you'll do all right here. btw I liked your question and Newbee's appropriate answer. I was not aware of how the 4 ohm and 8 ohm taps respond on different fq's. I still don't grasp ohm idea. Only that 4 ohm draws more volts/current from the tube amp. So it was a good question.

>>I get snides and insults due to lack of tech knowledge, snotty attitude, "mister-know-it-all", negativity, closed minded-ness<<

You make stupid statements.

If you open the door, people will walk in.
