Proline X Enclosures for Arc Audio Subwoofers

Audio Intensity builds Proline X CNC subwoofer enclosures matched to Arc Audio drivers. Each enclosure below is cut from the driver's Thiele-Small parameters on ShopSabre routers from Langboard Elite 3/4-inch MDF in Tullahoma, Tennessee, so your Arc Audio sub performs the way it was engineered to — including driver-matched Micro Series boxes for the SW-series shallow-mount subwoofers.

Don't see your exact Arc Audio model? We build to any driver's Thiele-Small parameters as a custom fitment. Contact us or call/text 931-563-5151 with your model and we'll spec the right enclosure.

Why a spec-matched enclosure matters

A subwoofer only performs as designed in an enclosure sized for it. These enclosures are calculated from measured driver data and cut to tight tolerance rather than approximated in a generic box. For the reasoning behind sealed vs. ported, see What is EBP? and What is Qes?
