My current system uses an Eminence Kappa 12 woofer and a P. Audio BM-D440 (1 inch, titanium diaphragm) on a B&C ME45 exponential horn. Despite top octave compensation I still find the sound somewhat lacking in the HF range above 10 kHz. Not really the "sparkling" sound i happen to enjoy. (But they do sound good). So I added a pair of KSN-1005 crossed in at 10 kHz which helped a lot. (Yes, you heard me right, the KSN-1005! They do not sound all that horrible above 10 kHz...)However, I am looking for higher quality drivers. Here is a list of different drivers I have been eyeballing so far:
"Bullet"
Beyma CP16
Beyma CP22
Fane HF250
P. Audio PST-555
JBL 2402 (WAY too expensive...)
"Slot"
Beyma CP21/F
JBL 2405 (again, out of the question.)
Experience with any particular driver, other suggestions or general thoughts are welcome!
