    Common Qestions and answers 

    Q: Will my subs fit this box?

    A: Use your subwoofer specs compared to box specs to verify. Make sure to check for Inside cutout, outside cutout, and mounting depth.


    Q: Is there enough air space for my subwoofers in this box?

    A: These Subwoofer Boxes utilize what is known as a "common chamber". In the simplest terms what this does is allow you to use multiple woofers that would need a combined air space greater then that of the box yours using them in while still maintaing proper air space for your woofers and their performance. Example; Your common 8" subwoofer will require .5-1 cuft of space "per woofer" in theory your box would need to be 2-4 cuft total. But because of the common chamber in the box you can still get optimal performance with a box that only have 2.8cuft. Each individual woofer will use the combined air space rather then use the space individually. Simply, your woofers wont know the difference.
