How to accurately gauge speaker sensitivity to match with tube amp?
I'm in the process of matching speakers to my amplifier and need a bit of advice. Most recently, I'm trying Focal 936 towers with my Quicksilver Mono 60w amp. They were sounding pretty decent until I experimented by hooking up my old Adcom 535L amp. All of a sudden, there was a giant jump in control, tautness in the bass, quickness in transients. The QS stuff was doing quite decently, but the Adcom really snapped these towers to attention. The mids and high ends, not to mention the soundstage, were worse with the Adcom — no question. But there was quite a difference with the other qualities just mentioned.
My question becomes one of sensitivity. The Focals self-rated as 92 db. Stereophile rated them as 89.5db. I realize that these are average measurements and a much bigger picture is told by the impedance graph (and other factors).
As I continue to search for the right match of speaker (I have a couple contenders), I'm sure one piece of advice is to look for speakers with higher sensitivity averages. But what else should I look for to help make a guesstimate about whether the amp will drive the speakers with the kind of control they are capable of? [Specs for this amp are here: http://quicksilveraudio.com/products/sixty-watt-mono-amp/ ]
I realize I need to hear speakers, in my house, with my gear, etc. to get a sense of them. I’m working in exactly this way. Your advice can help me eliminate candidate speakers that would pose similar challenges to my amp as these Focals have.
And I just bought the amp, so I don't want to change it.
Thank you for any thoughts.
P.S. Anyone who has has had great success with this amp or similar, please shout it out.

@atmasphere Thanks for your answer. You're adding more technical information that is pertinent to my narrowing down the candidates -- the comment that "the speaker should not go much below 8 ohms especially in the bass region" is very useful, indeed (at least, to me). These speakers are trials. They're going back. No cost to me because I can drop them off. The question is, "what's next." Thanks for your help with that project. |
Of course, this presupposes that the speakers you've become interested in have been measured reliably and that an impedance curve has been published. Fritz's standmounts do very well with low-powered tubes (I heard them with a Modwright SET headphone amp!!) but I'm not aware of published curves for the various models. |
@yogiboy 1.Room size? 430 sq. feet. 14x26 or so; listening on the long wall, about 9 feet away. 2.Type of music you listen to? classical, jazz, rock 3.Budget? 4-5k tops 4.Floorstanders or Stand mount? I'm open. Yes, Fritz's speakers sound very good. Been trying his Carbon 7s and will try Salk SS 6M's. A lot of folks were advising trying floorstanders, too so that's the phase I'm in now. |
@hilde45 You should check out the Spendor A line. I have used Spendors with my Quicksilver amps and the match was outstanding! https://www.spendoraudio.com/a-line-loudspeakers/ |
