I have a pair of the K9's -I bought them new 1988 !
I have matched them successfully for over 30 years with a a pair of Metaxas Solitaire high current power amplifiers.
The speakers and amps are in storage pending my return to Australia- Locked out for 3 years due to covid.
I am going to restore the Solitaires back to factory specĀ and get these babies back singing.
