Is the most efficient speaker the best speaker?

Ahhh Charles1dad,

A cylindrical horn does, it is the same as a linesource, unfortunately some call small waveguides horn and there qouted sensitivity is misleading ...

My Point;

We have to be careful when we compare speakers and there listed sensitivities....

regards,

Also in a system where the bass driver is loaded directly to the room, the drop off between both drivers are different in the critical lowmid/midbass region .

When purchasing such an hybrid setup system listening distance is very important and should be noted...

regards,

Hence the 3 db drop of per doubling would only apply to the Conical upper midrange/high horn and not to the system as a whole with these hybrid horn systems...

regards,

Gentlemen, I believe that the losses that are being referred to as being "per meter" should be "per doubling of distance."

I'm not particularly knowledgeable about horns, but I suspect that the 6db number is correct, *on that basis*.

If so, the 100db/W/1m would correspond to 94db/W/2m, and 88db/W/4m, and 86.06db/W/5m, according to my calculations.

Hello Al,

Per meter = doubling of measured reference distance..
