Box Sizes and Tuning

Each sub series is designed to work in the SQ box system. Each size sub in the series is designed for the same airspace and same response. Each series shares the same motor, spiders, suspension throw and power handling. The 10 inch woofer will play just like the 15 inch, but in a much smaller enclosure. Specifications listed below are for ported enclosures, if you wish to run sealed (recommended for HDS2 and HDS3's only) we suggest using half of the net volume.

^ft = cubic feet | sq" = sqaure inch
All volumes listed are after  vent, and subwoofer displacement; aka NET volume,
This chart is for tuning your enclosure in the ~35-40Hz range.

*Note - Multiple sizes are offered for those who need smaller enclosures for their application however we do suggest using the largest that will fit. Remember space makes bass!
