How is it possible then to fit two ports (one rear and one front chamber) in the enclosure BB recomends for the sub. VB
of chamber 1 = 0.751 (Port length = 17.61 Inches with 3 Inch diameter) and VB
of chamber 2 = 0.464 (Port length = 5.101 Inches with 3 Inch diameter). Just can't see fitting ports that long in the chambers.
