    Ik heb deze subwoofers aangeschaft als vervanging van twee (veel duurdere) Audio Technologies 23 cm C-quenze speakers gemonteerd in een gesloten subkast van 16 liter. Voor deze speakers gekozen vanwege hun specifieke specs voor een kleine gesloten kast. Bas loopt in vergelijking net de AT’s duidelijk verder door en valt in het laag onder 150Hz minder snel af. De Wavecor SW223BD02 liet vergelijkbare resultaten zien als deze SB-acoustics, maar is wel twee keer zo duur!

    Très bon sub, surprenant pour la taille dans 11 litres clos
