Hi morricab,
I would like use your speakers as an example. I'm not explaining it to you, as I know you already know this.
morricab's back loaded bass horn is 98db efficient. That is high efficiency is most people's book.
It is six db less efficient than the LS bass bin. That means the LS only needs one quarter the power to reach the same SPL as morricab's bin. That is, the LS can hit 98db spl with 250mw.
Let's take the Inlow Sound straight m/b horns. 110db efficient. That's a difference of 12db. That's one sixteenth the power requirement as morricab's speakers. The means the Inlow horn can hit 98db spl with 68mw. Yes, that is sixty eight milliwatts. And morricabs bass bin is a very efficient driver to compare against. Just think what those guys go through with 92db speakers. They need big amps.
Why does this high efficiecny matter? Lots of reasons. Two being, diaphragms don't have to move much, so you get low distortion. Also, and as important, it turns a 45 or 2A3 SET amp from an unusable curiosity, into a real power amplifier that provides all the drive you need and more. I have run my LS with a passive crossover on a 1626 Darling amp that put out 750mw. It was more power than I needed. I had loads of headroom. I could play the music loud as hell if I wanted to.
That's why.
I say if your really want to hear the full effect of a SET amp, you have to hear them on fully front loaded horn speakers. My two cents.
morricab I would really like to hear your system. I know I would like it.

Big speakers and little amps blew my mind!
