Sealed and Ported, Driver-Matched Cabinets

Rockford Fosgate Subwoofer Boxes and Enclosures

Sealed and ported enclosures cut for Rockford Fosgate subwoofers, CNC-machined in Tullahoma, Tennessee.

Proline X Performance P15D-P ported enclosure for dual 15 inch subwoofers.

Sealed and Ported, Driver-Matched Cabinets

Rockford Fosgate builds subwoofers that reward a cabinet cut to their actual parameters rather than to a nominal size. Every enclosure here is driver-matched, sealed or ported, machined in Tullahoma, Tennessee, to the figures Rockford publishes for the specific model it names.

Eight inch through fifteen, in wedge and down-fire forms. All of them are Performance Optimized builds on a 1.5 inch double baffle; the sealed cabinets ship with polyfill already installed and the ported ones ship without it.

Sealed and ported Rockford Fosgate enclosures from 8 to 15 inch, in wedge and down-fire, every one cut to a specific driver on a 1.5 inch double baffle.

Cut, assembled and finished in Tullahoma, Tennessee, to the parameters Rockford Fosgate publishes for each driver.

Driver parameters are taken from Rockford Fosgate published data. We build enclosures to those figures; we do not currently stock Rockford Fosgate drivers and make no claim to represent the brand.

Punch, Prime and Power: What We Cut for Each

Cabinets are cut per driver model rather than per nominal size, so find your line and model here, then open the listing for its volume, tuning and dimensions.

Rockford sells the T1 Slim 10 as two drivers, the T1S1-10S for sealed boxes and the T1S1-10P for ported ones, and the ported cabinets here are cut for the P. Shared across every cabinet: Langboard Elite MDF cut on ShopSabre routers in Tullahoma, Tennessee, and a Proline X ABS and carbon fibre composite terminal cup pre-wired in 12-gauge OFC. Sealed builds ship with polyfill installed; ported builds ship dry.

Every Cabinet Is Driver-Matched

There is no universal-cutout option on this page. Each enclosure is cut to the published parameters of one specific Rockford Fosgate model, on a 1.5 inch double baffle, so the net volume and the baffle are right for that driver rather than approximated for its size class.

We Cut the Box, You Source the Driver

We do not currently stock Rockford Fosgate subwoofers. These cabinets are built for a driver you already own or buy elsewhere, to the same published figures either way. Nothing about the fit depends on where the driver came from.

Wedge or Down-Fire, Eight to Fifteen Inch

Two shapes cover the range. Wedge cabinets taper on the rear panel so the baffle stays vertical and the box sits flush against a seat back or trunk wall. Down-fire cabinets aim the cone at the vehicle floor with the clearance designed in and feet that set it.

Sealed and ported, from eight to fifteen inch. Most are single-driver cabinets, with sealed dual wedges for the P3D2-10 and the T1D210. Polyfill is pre-installed on every sealed cabinet, because the fill is part of how it was tuned; the ported cabinets ship without it.

Rockford Fosgate Subwoofer Box Questions

Which Rockford Fosgate subwoofers do these boxes fit?

The cabinets here are cut for Rockford Fosgate subwoofers from eight to fifteen inch across the Punch, Prime and Power lines, including the shallow P3, R2 and T1 Slim models. Each product page names the exact model it was designed around. Match the model number rather than just the driver size, because two Rockford twelves from different lines want different net volumes.

Do you sell Rockford Fosgate subwoofers?

Not at the moment. We build the enclosures, cut to the parameters Rockford Fosgate publishes, and you source the driver. If you already own the subwoofer, these cabinets are built for it.

Are these sealed or ported?

Both. The sealed cabinets give tighter, more accurate bass in a smaller box and are more forgiving of placement, and they ship with polyfill already installed. The ported wedges and ported down-fire cabinets trade cabinet size for output around a tuning frequency solved for the driver and stated on the listing, and they ship without polyfill.

What is the difference between the wedge and down-fire cabinets?

Mostly fitment. A wedge tapers on the rear panel so it sits flush against a seat back while the baffle stays vertical. A down-fire cabinet aims the cone at the floor, which makes the floor part of the load, and needs designed-in clearance underneath. Pick the shape for the space; sealed or ported is the bigger acoustic decision.

Why is every cabinet the same series?

Because these drivers deserve the double-baffle build and we would rather not offer a cheaper universal cutout that undercuts them. Every Rockford Fosgate cabinet here is Performance Optimized: a 1.5 inch double baffle cut to one driver.

Can you cut a size or shape you do not list?

Possibly. Everything is CNC-cut to order in Tullahoma, Tennessee. Contact us with the Rockford Fosgate model and the space you are working with and we will tell you whether we can build it.
