There are two loudspeaker criteria that are important for SET owners in addition to the usual matters of sound quality. One is efficiency and the other is impedance. You need high efficiency because amplifier power is limited and impedance peaks should b...

Well, I see below that your recommended cutoff for Zmax and tubes is 50 ohms. How bad is the 75-90 ohm range going to be?

When using a tube amplifier, most know to look for speakers with high efficiency ratings. What is sometimes overlooked is impedance. This is important too because it may affect the response curve in some cases. I'm not talking about its (8 or 16 ohm) &...
