Horn Speaker Efficiency

classAchap · 14th October 2008, 09:38 PM

I'd appeciate some guidance on horn efficiency. What info I've been able to find suggests efficiencies of from 30% to 85% - so it could be anybodies guess!

I made my own-design wide-range horn and I reckon it's efficiency is 10% at most - probably less. I'd really like to know what efficiency it would be reasonble to expect and is there a theoretical maximum - or any comments.

Note that efficiency is frequency dependent because electrical impedance is not flat and 2.83V/1m sensitivity is not flat either. It may be as high as 50% for some frequencies and as low as 10% for others.

Try Hornresp software if you haven't got it yet.

Isn't some generaly accepted working efficiency range for horns then? In the same way you'd know the general efficiency for a relex speaker say, or a class A or class B amp - or D or G for that matter.

Thanks BTW, I've now got Hornresp - I'll give it the attention it deserves once the balsa dust has settled.
