DD Audio’s service technicians are trained to aid our customers with subwoofer enclosure design needs via the tried and true DD Box Design system. The DD Box Design system is a powerful tool developed to allow system designers the ability to easily design high efficiency, ported enclosures for the majority of daily listening systems. However, to realize the performance goals for some mobile audio systems the subwoofer enclosure design will need to go beyond the scope of what the DD Box Design system was intended for.

If your enclosure needs fall into this category DD Audio has you covered. We have a nationwide network of highly experienced DD Audio dealers we can refer you to for a full custom system design experience from sales to service. For those that don’t have an authorized DD dealer in their area we have also partnered with some of the most talented, professional enclosure designers in the industry to offer our customers a custom enclosure design service.

Both our dealer network and the designers we’ve partnered with have in-depth knowledge of DD Audio equipment, and the ability to offer design advice on all types of enclosures including sealed, ported, and bandpass designs based on the customer’s specific application.

If you’re ready to take your system above and beyond, start by filling out the Custom Enclosure Design Request From below.

To properly assess your enclosure design needs please provide some basic system design information.

Once DD Audio has received your completed request form one of our service technicians will be in touch with you to either advise you on your enclosure design or to let you know we will need to forward your request to one of our design partners in order to properly assist you.
