JL Audio 12TW3 Sealed Shallow Down Fire Enclosure, Dual 12″

JL Audio 12TW3 dual sealed shallow down fire enclosure for a 12-inch driver: 1.72 cu ft net, Qtc 0.920, F3 37.6 Hz.

Qtc 0.920 means a compact box for this driver. The response peaks before it rolls off; it makes sense when space is tight and the vehicle cabin will add back low end.

Firing into the floor adds boundary loading, so in the vehicle it plays deeper than the anechoic figure suggests.

The driver faces the floor, so luggage cannot reach the cone and the top stays flat for cargo. It is built shallow for tight spaces, so check the mounting depth figure below against your driver.

Listed construction: 3/4-inch MDF, with a doubled 1.5-inch front baffle, dado and V-groove panel joints, black carpet, polyfill installed, pre-wired terminal cup.

Your subwoofer's mounting depth needs to be 3.5 inches or less. Each driver gets its own sealed chamber. Send us your subwoofer model and we will check it against this box before you order.
