    Bisher konnte ich die akustischen Eigenschaften des Lautsprechers noch nicht beurteilen, weil mein Subwoofer Projekt noch nicht fertig ist. Als einstiger Lautsprecherentwickler kann ich aber sehr gut die Qualität der verwendeten Materialien, die Konstruktion und die Fertigungsqualität des Chassis beurteilen und das ist alles schlichtweg überragend! Ich bin sehr auf die ersten akustischen Versuche gespannt und werde dann ggf. wieder berichten.
