Arc Audio ARC 12 Ported Wide Enclosure, Dual 12″

Arc Audio ARC 12 ported wide enclosure, dual 12-inch, with 3.16 cubic feet of net airspace tuned to 33.5 Hz through 32.6 square inches of port; the anechoic F3 is 30.7 Hz.

Tuning at 33.5 Hz is where the port takes over from the cone. Above it the box behaves like a large sealed enclosure; around it output rises several dB for the same power; below it the cone unloads, so set a subsonic filter 5 to 10 Hz under tuning.

32.6 square inches of port area keeps air velocity down at high output, so the port does not chuff when the music gets loud.

The wide format spreads the volume across the trunk rather than back into it, keeping depth short.

Polyfill pre-installed.

The drivers share one chamber, so run matching drivers wired to the same impedance. Not sure the driver matches? Send us the model number and we will check it against the spec sheet before you order.
