Is the most efficient speaker the best speaker?

Hello Charles1dad,

To achive 94 db@5M the SET.horn combination in my eg would require 64 watts from it's 20 watter, the planer approx 90 watts from it's 200 watt amp.

Also to achieve realistic size, dynamics and lowest distortion( not just the loudest spl) we have found most amplifiers give there best presentation @ approx 33% of rated output. ( avg Din)

Regards,

Agreed Charles1dad. Your system is awesome and I have always had an interest in both your amps and preamp. Very nicely put together.

Would any builders of horns care to comment? I don`t believe horns lose 6db per 1 meter at all, 3db is the correct value.

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,
