Did anybody get horns figured with triodes ?

I can run my Lowthers with 1 to 2 watts and blow you out of the room. Big horn speakers like Altec A7's with over 100db efficiency can run on 3/4 to 1 watt easily

"I do not know about now but back a while ago I finally figured out the fewer gain stages the cleaner the sound but how can you run a speaker with less than 5 watts?"

I know what you are saying, but there are other factors that effect how clean sounding the amp is. Also, if you need more power, you can go SS. My Pass amps had only 2 gain stages. They had similar sonic qualities to low power tube amps.

I run a 99 db/w system with a compression horn midrange with a 5 watt pushpull amp or a 6.5 watt parallel single ended 2a3 triode amp. Both are quite adequate for the job. The only time I feel the need for more power is when it is playing acapella choral music; for some reason, this type of music begins to sound a little more muddled at surprisingly lower volume than other kinds of music.

The best thing about horn systems and really good low powered amps is that the music is VERY satisfying at LOWER volume than other setups. I find that the better my system gets, I listen at lower and lower volume.

I use SET PP SS etc on my horn systems not all have synergy with SET power but most do.
