The volume of the rear chamber should change if another compression ratio is used. In fact this volume varies lineair with this ratio.

For some horns it really makes a difference if the volume is chosen wrong. Might cause 5-6dB bumps! Use McBean to model a rearloaded hyberbolic horn with:

l=2.8m
ah=75cm2
am=850cm2

In this case the volume should be kept as small as possible!

Best regards,

Walt
