Very good drivers - don't stuff about with guesswork - get them professionally tested - well worth the cost and effort.

Send them over here to Melb - quite a few places will do the full test, including w/fall, transient, FFT,etc, etc - not really a problem if you have the original or good travel boxes for them.
Lorrantz Audio will also do a suitability/use/evaluation on their big computers if you can tell them what you want to use them for and develop "optimax" box parameters for you too, etc
