I'm agree with you dB.
I'll make 2-way system and HP it 80Hz. CP-21F will cut 2-nd order 5kHz. I want to use high sensitivity Beyma because I'll use 2 of Alpha 8. I'll use L-pad for BeymaIn specifications of Alpha 8:
Usable Frequency Range 65Hz - 5kHz
Do you think that will be good frequency responce speakers?
