The product it self is amazing subwoofer is perfect great quality but i can't tell how disappointed i'm in masori shipping it said 2-4 business days and it took almost 3 weeks for amplifier i still waiting.
Die Mille Serie von Hertz ist einfach großartig.
Grandioser Sound bei jeder Lautstärke.
Der Woofer ist bedenkenlos zu empfehlen.
Ótimo produto muito bom bem reforçado um grave absurdo um alto-falante de alta performance instalado bem certo limpadores de qualidade controladores de som e bateria você terá um grave absurdo em seu sistema
Einer der besten Tiefmitteltöner im 10cm-Bereich, Top Verarbeitungsqualität, sehr hochwertige Materialien, hervorragende tiefreichende Mitteltonwiedergabe.
Ich habe sie an den Sounddigital 800.4 Evo6 angeschlossen. Und ich bin mehr als zufrieden. Mitteltöner laut und auch präzise. Hochtöner brennen nicht in den Ohren, die sind laut und geben das, was sie sollen. Gut angelegtes Geld.
Perfekter Verstärker, Lieferung wie erwartet. Top-Unternehmen.
das ist super 👌👌👌
Kam gut verpackt an und liefert sauber seine leistung
Dies ist eine hervorragende Option für eine kräftige Serndina. Ich empfehle sie.
