Hey folks,
the old Alnico drivers with ALuminum diaphragm such as the 2440 and 2441 are still sought after because of their great sound.
JBL changed these to Titanium diaphragms in their ferrite successors like the 2445 because of their greater resistance....
The 2450sl is the newest of the mentioned drivers and was used in hifi and studio-monitors, but not in pro audio if I remember correctly!?
The 2450sl uses an aquaplased Titanium diaphragm and itīs primarily purpose is to sound good, not resistance!
Why does JBL use aquaplased Ti diaīs instead of AL diaīs in a sound quality speaker
I know the aquaplas coating reduces resonances and the "ringing" of the Ti diaīs.... But why wouldnīt JBL use a less "ringing" material such as Aluminum right away, instead of using a material of less audio quality and correcting itīs "faults" afterwards by coating it with damping material?
If these drivers where used in pro audio at concert levels all day, I would understand choosing the more resistant Titanium.
But isnīt the Aluminium resistant enough for quality sound applications at studio environments?
Or did the guys at JBL believe the aquaplas coated Ti diaphragms do even sound better than the Al diaphragms?
