Installer's take

The 2.75 ft³ net volume gives dual 12" drivers real room to operate in a ported alignment. This is not a compressed box tuned tight to hit a compact dimension, the internal volume is sized to let both drivers work efficiently at the 36Hz tuning point. The result is output that reflects what the drivers are actually capable of. At 32" wide and 15.3" deep this is a dedicated trunk build. Measure both dimensions carefully before ordering. Width and depth are both critical here. The 7.125" max mounting depth covers most standard 12" drivers. Single terminal cup handles both drivers internally. Both must be run at the same impedance. Confirm your amplifier output and driver impedances before wiring.
