I have picked the MAD1259 Polypropylene subwoofer for my project.
This well known woofer had shown nice performances in many subwoofer projects around the world. This is an advanced version of the old NHT 1259 and was mafe by Foster. It was especially designd for sealed enclosure subwoofer boxes and suits music high end critical listening apllicaions.
