The xover freq and the drive units are .....

Posted by akltam on July 13, 2017 at 01:00:33:
The crossover freq will be 600 Hz and 3000 Hz.
I have a number of different setup, but you can assume a general set of drivers.
setup 1: Seas Excel C18EN002/A (E0060) 6.5" Coaxial. The mid is 87db and the tweeter is 90db.
setup 2: Dynaudio D76 (90db) as the mid unit and a SEA T29MF001 Magnum tweeter (92db)
setup 3: Volt VM752 (92db) as the mid unit and a ScanSpeak D2908/7140 Beryllium Dome Revelator Tweeter
The bass units are twin Scan 18w/8531. Or I can use another box with twin Scan 25w/8565.
I have an impression that 25w for the mid driver may not be enough.
