2018 Honda Civic dual sealed subwoofer enclosure for a 12-inch driver: 0.61 cu ft net, Qtc 0.851, F3 41.3 Hz.
A Qtc of 0.851 adds a little lift before the response rolls off: more impact than a textbook alignment, still tidy on fast bass lines.
Built for the 2018 Honda Civic: the shape follows the factory space so the box fits without losing the volume the driver needs.
Listed construction: 3/4-inch MDF, with a doubled 1.5-inch front baffle, dado and V-groove panel joints, black carpet, terminal cup.
Your subwoofer's mounting depth needs to be 3 inches or less. Each driver gets its own sealed chamber. Tell us which subwoofer you run and we will confirm the match first.
