KEF B200-G horn loaded

B.I.G · 5th August 2004, 08:37 PM

I have this driver an i want to make a horn for it like this : http://homepages.paradise.net.nz/quadroph/digitor.htm

My question is should i expect such a huge SPL like David J McBean`s software says ?? i mean 118dB at 40HZ wtih just 70W (it reaches Xmax12mm

) of power is quite a bit for a 90DB speaker .

The model is stated in eighth space- corner loaded, that is- and as such the anticipated output is quite likely. It would drop precipitiously otherwise but yes, high output with low power is what horns are all about. Here is a link to a measured SPL chart for my Tuba 18, an 18" cubed box loaded with an eight:
