Bd-15 frequency response (BD-Design)

Hi Stephan,

Are there any measurements of the frequency-response of Your BD-15
drivers, mounted in the Reference-set up, but without any crossover
existent?

I do not have any and making one would not be relevant as this will show you the interaction within my listening room...

The response starts to roll-off slowly at around 120-150Hz down to 30Hz at -9dB. Under room conditions the bass will roll-off less steep though...

Above 150Hz the respons is flat up to 800Hz (in all directions, no serious breaking ups) and from there starting to have less dispersion but still linear to where you do not want to hear them anymore as it then does not act as a piston anymore.

Crossing at 400Hz (minimal 12dB, better 24dB but depending on what you are going to use on top of that) is no problem at all.
