Proline X

Dropping a Solo X into a random prefab is like putting race‑fuel in a lawnmower.

The Proline X X‑Series is a full lineup of ported enclosures built around KICKER’s Solo X subs—net volume, tuning, port area, and bracing all dialed for real power and extreme excursion. Single, dual, and triple boxes for Solo X 8s, 10s, 12s, and 15s, ready to handle serious wattage and abuse.

Whether you’re building a brutal daily or chasing numbers, start with an enclosure that’s made for Solo X from the ground up. Hit Shop Now or visit https://audiointensity.com/collections/proline-x-x-series-enclosures-built-for-the-kicker-solo-x to see every X‑Series option.
