Crossfire C7 series - Specifications and Dimensions

Thiele-Small Parameters:
these vary from unit to unit and also according to measurement technique, so don’t get too hung
up on exactness of the numbers or box design results. By the way, “pk-pk” means peak-to-peak.
Sensitivity (No):
This spec is omitted because it is for mid frequencies and misleading for subwoofers.
Woofer Displacement Volume:
For standard drop in mounting, please subtract the subwoofer’s displacement volume from
the gross enclosure volume to calculate accurate net enclosure volume.
Vance Dickason’s Loudspeaker Cookbook
contains tons of useful information and we highly recommended it
