Ultimax ii 18“ in einem 320l Dual opposed Gehäuse betrieben mit einem Tamp e1500 Bridged

Ich habe die Treiber nun seit ein paar Tagen im Einsatz und bin höchst zufrieden. Sie spielen beeindruckend tief und erzeugen nahezu keine außerhalb der Box wahrnehmbaren Motorgeräusche – zumindest bei der Leistung, die mein Verstärker liefern kann. Durch ihre 18-Zoll-Größe bieten sie zudem mehr als genug Output.

Ich habe einen Treiber gewogen und meine Personenwaage sagt 19.1kg an.
