From the All Fun Horn page:A larger cavity between the driver and the throat of the horn lowers the upper cutoff frequency of the bandwidth feeding the horn:
Upper cut-off frequency = c * At / (2 * p * V)
Where:
V = Volume of cavity
At = area of port, i.e. horn throat area
c = Speed of sound
So increasing the volume behind the driver means less midrange into the horn.
