Custom made to fit DD Audio 500 & 600 Series
Take your DD Audio subwoofers up a notch with the Proline X enclosures built to maximize your DD Audio 500/600 series subwoofer performance. These enclosures are built to spec, making sure each enclosure has the right airspace for your subwoofer. All of these enclosures are ported, carpeted with grey trunk liner.
Why Proline X?
Proline X relies on over 30 years of industry experience and leadership to create high-quality subwoofer enclosures. Based in Northern California as a subsidiary of Audio Intensity, Proline X products are American-Made and a veteran employer.
Enclosures are CAD optimized, precision CNC cut, and assembled by hand with stringent quality control throughout assembly to completion. You won't find better boxes for the price anywhere.
Why DD Audio?
The 600 Series subwoofers are not for the faint of BASS! From the top down they are built for extreme sonic performance. Heavy duty double stack magnet motors and long throw voice coils handle the power while Power Tuned suspensions with EROM surrounds and a progressive dual spider system keep the moving parts linear and distortion free during high excursion play. The 600 Series subs work best in vented and multi order enclosures.
