Enclosure Info
RE subwoofers perform well in any size sealed enclosure between Compact and Optimum volume recommendations.
ese systems will exhibit benefits of both designs: “Compact” produces high impact bass and “Optimum” generates
greater low bass frequency extension.
(sealed enclosure application - moderate efficiency)
• e Compact design increases bass efficiency and fits in many space-limited applications. Although it is the smallest
recommended ported enclosure, the output from 30 to 80 Hz will be considerably higher than that of any sealed box.
• e Optimum is the largest and most efficient enclosure design. It delivers the sonic output needed to win SPL
competitions.
(ported enclosure application - high efficiency)
