Flea Watt Amp: What Speakers Are. You Using With Yours? Recommendations

I use a Miniwatt with 2.5 watts output and it easily powers either my Klipschorns or my Zu Soul Superfly’s which are 16 Ohms. I also have 6 watt and 12 watt vintage Mullard amps that drive them easily too.

10 watts with either Merrill Zigmahornets or Coincident Mini Truimph 

How about Tekton? They have some high efficiency speakers that seem to be highly rated and reasonably priced. 

I love my tube equipment, and large horn speakers, and highly recommend getting high efficiency speakers to use with tube amps,

but, 8 to 12 wpc? I personally would not go down that path. I would sell those low powered amp(s) and rethink ...

I think the 25-45 wpc tube amp range broadens the range of available speakers. And, 'generally' speakers get large and larger as high and higher efficiency is required. Not all spaces can properly co-exist with large or larger speakers.

IF you had heard the amps, fell in love with them, just had to have them, well, that probably is the case for the majority of people who use them. My friend fell in love with 300b 8wpc, and uses them with his not too efficient speakers. They sound terrific at low volume close listening, but that's it.

Of course, 1 way to approach this is to start with a self powered sub, that takes the need for bass (the real power demand) away from the tubes.

I use my 4 watt Decware Mini Torii with 92db Ref 3A de Capos. It gets loud but not so loud the neighbors come knocking

I use my 2/6 watt Grommes PHI 26 with 97.5db Klipsch Quartets, it gets loud and it is sometimes hard to get it to play quietly
