Eminence Kappa Pro-18LFA

Hi folks,
I had to replace the second 18" speaker in an original HK sub (D.E.A.CON series) system. After rather long investigations (I also called directly HK who told me not to do this) I eventually decided to replace the weaker original HK 500W speaker (made by Eminence (... !) costing 100 ¤, by this Eminence Kappa Pro-18LFA delivering 300 W more.
All I can say is: It works perfectly fine. Exactly same size, the screw holes match (no drilling at all) and the sound is barely different, maybe just a bit tighter. Hey guys, this is the speaker to use for replacement ! If ever I have to re-replace the first one (with an original HK) I will bay an Eminence Kappa without hesitation. Almost 100 ¤ cheaper AND stronger !!!
