Bd-15 frequency response (BD-Design)

Stephan,

Is the roll-off You mentioned with the Oris 150 horns?

No, then the useable response is limited to 325Hz where it starts to roll-off due to the acoustical filter (the horn) in the higher frequencies.

It can be extended to 400Hz though by using a smaller throat for the 150 in front of the bass as used today.

Important is the flat response from 150 to about 600 Hz, to have a smooth
transition and also to have the same dynamics and dispersion as from the
midrange/tweeter system.

The response is smooth up to 800Hz acting as a piston (or 900Hz, can't remember exactly) and the dispersion similar to all drivers reaching the wave length limit that gives less dispersion (mother nature causing this!).
