$565.99
Arc Audio ARC 12 ported wide enclosure for a dual 12-inch driver: 3.16 cu ft net, tuned to 33.5 Hz, 32.6 sq in of port, F3 30.7 Hz.
Around 33.5 Hz the port does most of the work and output climbs several decibels over the same driver sealed. Below 33.5 Hz the cone is no longer loaded, so set a subsonic filter a few hertz under it.
With 32.6 square inches of port, air speed stays low enough that the port should stay quiet at high volume.
The wide footprint spreads the volume across the trunk to keep the box shallow.
Listed construction: polyfill installed.
Both drivers share one chamber, so use a matched pair wired to the same final impedance. Send us your subwoofer model and we will check it against this box before you order.
