What speakers work with low wattage class A amps

After years of accepting the colorations of my 12 inch 96db full rangers, I just prototyped a pair of Bohlender Graebener 4 ohm satellites.

They have a nice flat 4 ohm impedance, which my old style class A can deliver 15 watts to per channel.

Not quite an open baffle, they are sized to act as a passive highpass augment and fit on stands, while an open baffle panel handles bass to 80 hertz with its own larger AB amplifier.

I have until recently had a pair of Living-Voice OBXRW speakers and have driven them with an 18WPC parallel 300-B tube amp, First-Watt SIT-2 and F8, and a Valvet E3 all of which sounded terrific and were easy to drive with their 93-db 6-ohm nominal impedance.  These are all flea-watt amps and each display their individual sonic signature but all sounded great.  Can't recommend them highly enough.  

My DeVore O/93's work great with low wattage amps.

I spent all day yesterday listening to my Fritz Carbon 7 SE speakers powered by a 3.2 watt Sayes 2a3 SET and that amp drove the Fritz’s beautifully
