RECOMENDED PORTED ENCLOSURES
These recomended enclosures are general enclosure recomendations and can be
varied to suit each customers application. For SPL type applications, enclosure
volumes and tuning frequencies will vary for each application. For custom enclosure
applications please contact Crossfi re Technical Service Dept.
All enclosure recommendations are based on net enclosure volume.
Please add woofer displacement and port displacement to calculate accurate net
enclosure volume. Example: C7 12D1 has a woofer displacement of .136ft3 and a port
displacement of .29ft3, So your ported enclosure needs to be 2.7ft3 gross volume
before all displacements, giving you a net volume 2.25ft3.
