DD Audio DD1506-D2 ESP is an insanely good 6.5 inch subwoofer DD Audio had an ambitious goal when designing the DD1506-D2 ESP element. To create a subwoofer that would actually work in a really small enclosure. DD Audio’s subwoofer expertise of over 20 years has paid off again. The best materials and design combined with meticulous hand-crafted assembly work. The result is a SMALL SUBWOOFER with GREAT PERFORMANCE. The DD Audio DD1506-D2 ESP is the right choice if you want a subwoofer that plays loud, plays well, lasts for years and REALLY WORKS in a small enclosure. DD Audio recommends a break-in period of about a month for all its subwoofers. It is never a good idea to play a new subwoofer “with the knobs turned all the way up”, but to let its suspensions soften during break-in with more moderate use. During break-in, the sound improves all the time and the performance also increases in terms of sound pressure.
