That's good. Anything over 90db is good for me. I only build SE (and SE\UL) tube amps. My lowest wattage amp is a 6EM7 integrated with a tube preamp section but only produces 2.5W. On my Fostex FE206Ens it is very loud. The amp would go well with your speakers. My most powerful is 5.8W 300BSE.

Try a DIY SE tube amp with the speakers. You may get a very big surprise.

I dont pretend to be the first time inventor or something like that.
But also did not read Bailey papers when was designing. For me a "push" for that was one order from customer. And main issue was - how to make many turns and still keep triangular, in determined outer dimensions.
Does not matter, the main thing - sound is good) Now will make a search for that 1972 issue. You know, previously Ukraine was a part of USSR and we were reading totally differet magazines with you))

So you had a good catch! A different geometry when/where there are no
parallel walls, I know it's better. The 'stimulus' is not reflected and bounced
inside with regular patterns like in parallel (epipedus!) boxes ...

The Triangular Etc etc design I found was on a book for building boxes that
I bought many years ago, and it's from a German guy. I used to read EWW only in the nineties, just when some 'audio related' articles appeared.
