Hi,
The upper limit of Low frequency driver is upto ka=2(k being the wave number and a the diameter of the driver). I want to understand how the full range driver operates above this range, does it make using of decoupling and use just the dome?. And also if anyone knws the advantage of either when the volume is really small( aprrox 200 cm3.)
Thanks

An awful lot of simplifications & generalizations to come up with that equation. The actual numbers will have significant range.

I believe that to be true because when i simulate a driver in infinite baffle the omnidirectional characteristic is above the range of ka=2 but there is a pattern of directivity increasing as radius of driver is increased.
