Sie bieten auf die abgebildeten Tief- Mitteltöner von Scan Speak. Es müsste sich um den 18W/8543 handeln, allerdings ohne Garantie, es sind schon ältere Modelle und leider keine Aufkleber mehr drauf. Technisch und optisch sind sie in gutem Zustand. Die Sicken sind nach meiner Meinung bereits etwas verhärtet, allerdings noch völlig intakt. Auf dem letzten Bild sehen Sie den Lautsprecher in dem sie verbaut waren. Die Lautsprecher kamen u.a.als Mitteltöner in der Transvector 4 zum Einsatz. Abholung ist ebenfalls möglich.
