| | Folded Horns - whats the deal
I recently, (foolishly?) have been thinking about constructing PA speaker cabs.
I've been looking at bin designs horn loaded bass bins in particular, and 1 thing strikes me as odd about the designs of bass horns I have been looking at.
They seem to have a very small sealed cavity of air behind the driver.
This would seem to be at odds with the general principle that bass speakers require large enclosures or tuned ports, and I would have thought this would create significant resistance on the cone movement and reduce the efficiency of the driver. This isn't the case with scoops and many sub designs, yet many tried and true bass horn cabs seem to have this very small cavity behind the driver
So, what am I missing here....
