Es gibt Definitiv einen Unterschied zwischen einem Motor mit und ohne Turboaufladung.Mit einem Turbo kann man mehr Leistung herausholen aus einem kleinen Motor. Dasselbe gilt auch für unsere Technologie acebass1.Die Leistung einer kleinen Box, die funktioniert wie ein viel größerer Subwoofer.Mehr Bass in einer kleinen Box.So einfach ist die Ace-Bass-Technologie von Audio Pro.Bass zu produzieren bedeutet große Luftmengen zu bewegen. Die gebräuchlichste Methode hierfür ist die Verwendung einer sehr großen Kiste und einen sehr großen Tieftöner. Aber mit Ace-Bass erhalten Sie tiefe, kraftvolle Bässe auf eine intelligentere Art und Weise.Durch Mechanik und ElektronikMit Innovationen ist es uns gelungen, die Natur zu „täuschen“ und gebenunseren Basslautsprechern mehr Leistung als eigentlich möglich sein sollte.Mit unserer Ace-Bass-Technologie können wir dasWir stellen Subwoofer in sehr kleinen Gehäusen her, die noch immer funktionieren.Sie haben einen extrem tiefen, reinen, schnellen und kraftvollen Bass. Vergleichbar ist ein Audio Pro Ace-Bass-Subwoofer zu einem Turbomotor.Turbogeladene Motoren sind kleine Motoren mit extrem guten Eigenschaften und Leistung für ihre Größe. Die Ace-Bass-Schaltung ist die Turboladung des Subwoofers.Die Vorteile von Ace-Bass liegen auf der Hand: mit einem kleinerenBass in der Box lässt sich der Subwoofer problemlos platzieren oder verstecken wenn gewünscht.Die kleinere Box bedeutet auch eine stärkere Konstruktion, mit besserer Dämpfung und weniger Resonanzen.Sie erhalten tiefere, reinere, schnellere und kräftigere Bässe als das, was „normalerweise“ möglich ist.So ein kleiner Subwoofer. Das gleiche Gefühl, das Sie bekommenwenn Sie in Ihrem Auto mit Turbolader am Steuer sitzen.Ein tolles Gefühl, finden Sie nicht auch?

Pro Audio Subwoofer B2-50. This is a working Subwoofer. I had this tested at a local Electronic repair shop. It works fine. One of the drivers was replaced , and there are minor chips in the veneer on the front baffle, but with the grill on, you wont see them. Obviously, this does not affect performance. I dont have the wires to connect these to a system. You will have to purchase those separately. Because of the size and weight of this item, I am listing this as local pickup. If you want to arrange pickup, and shipping, you can do so after purchase.
