      For my old Autovector speakers, I have replaced all mid-woofers with this unit - SB Acoustics SB17NRXC35-8 Perfect - highly recommendable.

      Das Chassis schlägt sich sehr gut, das Preis-Leistungsverhältnis ist hervorragend. den Bass finde ich um die 100 bis 150 Hertz etwas präsent, das kann man aber leicht rausnehmen und lieber so, als anders.
