Re: A question for the horn fundis

198.182.208.35

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.
