too brief, though you piqued my curiosity.

sound pressure now?

my ears bleed just thinking about it...


Well, I had to make a guess at what the OP wants to do with all of 500W, and the obvious answer is a very big wall of sound in a very big space, which is why I brought up the Bessel Array. The horn I also mentioned is better scaled to domestic situations though, as I also demonstrated, with minimal effort it can be made to go BIG.

However, I must tell you, in an open-plan house I divided a floor between my study and my studio with a Bessel wall of ESL-63, driven in stereo by QUAD II (all the gimmicking was done in a custom preamp) and later by ex-BBC silicon QUAD amps rebuilt at the factory, and that was a superb domestic implementation, albeit one where you had to be careful with the volume knob if you didn't want to land in the divorce courts. I could walk around in the orchestra that setup made. So, if you have your mind in gear, and maybe have the components already, Bessel does scale, but in general you're right, Bessel just isn't economical or practical to build from scratch unless you want to reach thousands of people.

The best sound is mainly a matter of what you're used to hearing
