Sorry Galu, my imagination ran away while I was thinking about a squared-off version of Focal's smaller Kevlar-coned T90.
Is the woofer an Audax?

Looks much like it could have been built by Falcon.

Thanks for the reply. So you have a MA4 Series 1 and I hope you are now able to replace those original ELCAP capacitors which may have deteriorated significantly by now.

Since the ELCAP capacitors were bipolar electrolytics, you may wish to substitute them with modern bipolar electrolytics which should restore the original sound balance of the speakers. Look again to Wilmslow audio for these: Mundorf Electrolytic ECap Capacitors
