Question about tube friendly speakers...


I want to check my understanding of speakers. Here we have two speakers: A & B. Both of them have the same physical dimensions, use same sized woofers and woofer configurations, both have same sensitivity 90db, both handle between 25 to 200 watts, but A has an impedance swing between 4ohm and 8ohm, but B has an nominal and steady 8ohm load. And both powered by the same by, let's say, VS55 ARC tube amp.

Which will sound better with a tube amp? I think will sound better.

What if A is twice as expensive as B because of higher quality parts and build, which will match better to the amp?

Am I right?

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
Audiogoners, hypothetically, based on specs alone, are the specs I provided on the speakers enough to make a theory-based choice on speakers? If not, what more is needed? Say this info will be used to build a short list of speakers to be auditioned at a later time(it would take a lifetime to audtion EVERYTHING).

Next, what kind of info is then required to know about the amp you will be using if wattage and ohm tap is not enough?
I believe that in your case you should select the speaker with no less than 6 Ohm minimal impedace(usually rated for lowest freequencies)
Audio Note Type J speakers operate between 6 and 8 ohms is what I've been advised by Audio Note. They work great with transformer tube amps. I use a P2SE with 18 watts and the SPL is way more than I can handle; plenty of power.
