Consider that the old Dynaco A25 was measured at 82db, and several of the vintage AR speakers were in the same range at 82-83db. As well as the classic BBC 3/5a type speakers. Many people used 15-20 wpc tube amps to drive them. 20 watts into an 82db speaker is equivalent to 5 watts into an 88db speaker.

I have a 30wpc tube amp driving 84.5db speakers in my bedroom. That's a bit more headroom than what you have but to the best of my knowledge I've never clipped that amp.
I owned a pair of Dynaco A25XL’s, which were alleged to be 3dB more sensitive than the A25’s. I could run them with a 6wpc Tripath amp to high levels in my room. The A25 series had a 10” woofer that ran with no crossover elements at all. I think this well-behave driver running unimpeded made it very easy to drive.

It's good to know that I shouldn't be giving up much with these speakers. I appreciate the input! Back to more listening and tube rolling

I had built the speakers shortly before deciding to go the tube amp route. I have a little regret that I didn't wait and buy a more efficient speaker, but they do sound great in my fairly small room and I'm not wanting for more volume. I selected the Mundorf Evo Supreme Gold/Silver/Oil cap option and I'm amazed by the performance of the tweeter. I can't get over how great everything sounds. Instruments and vocals alike have a sweetness and realism to them. Any changes to gear or tube rolling is immediately evident. I'm curious if more efficient speakers would increase dynamics or bass slam, the bass is quite nice with the right tube combination though. I'm glad this SE amp has the grunt to make lower efficiency speakers sing!
If it sounds good to you...it is good. Trust your ears and enjoy.

updated my small test (mule) speakers with some Scanspeak midrange/woofers and a few more crossover mods. Matching the right speakers with these amps has been a learning process, and worth doing.

I'm running Serenity Acoustic Super 7s, one of only 7 made before the company went out of business. It uses a quad of BG Neo 10 midrange drivers crossed over to a BG Neo 3 tweeter in a wave guide. Bass is handled by dual 12 inch powered servo subwoofers from Rythmik Audio in an open baffle configuration. Subs handle bass from 20hz to 200hz, and the midrange/tweeter handles everything from 200hz to 20khz.

Basically my Inspire amp drives the top part of the speaker, from 200hz to 20khz. That part of the speaker is 97db efficient and has a very, very, very flat 7 ohm impedance. Almost a perfect speaker for low powered tube amps.

Default I am using Klipschorns with Inspire Firebottle PSE

I am using a pair of modded Klipschorns with my Inspire Firebottle PSE amp and matching Inspire LP-3a preamp.I love the sound of this combo deep bass with smooth top end and wide soundstage,plus it is dead quiet between tracks.
