Our take on the Rockville RHB12

The Rockville RHB12 is a single 12-inch sealed subwoofer enclosure built for hatchbacks and small cargo areas. Its slanted front maximizes air space in tight spots, and it is made in the USA from 3/4-inch Grade A MDF rather than thinner import wood. Joints are glued, stapled and silicon-sealed, so the box resists flex that muddies bass. It suits drivers who want a sturdy, ready-made sealed box for one 12-inch sub and don't want to build their own. Against generic prefab boxes, the thicker MDF and extra sealing are the main edge; it is a plain enclosure with no terminal cup or wiring included.

Best forHatchback and small-SUV owners fitting one 12-inch subBuyers who want a sealed box without building oneDrivers chasing tight, accurate bass over maximum outputAnyone upgrading from a thin particle-board prefab box
Pros
  • 3/4-inch Grade A MDF resists flex better than thin import wood
  • Slanted hatchback shape makes the most of limited depth
  • Glued, stapled and silicon-sealed joints
  • Carpet held with enhanced adhesive that resists peeling
  • Made in the USA by an enclosure maker with decades of experience
Cons
  • Sealed design gives less output than a ported box of the same size
  • No terminal cup, wiring or mounting hardware included
  • Cut for a single 12-inch sub only, so no upgrade path
  • Heavy MDF box is awkward to move and install alone

About the Rockville RHB12

The Rockville RHB12 is a sealed hatchback enclosure for a single 12" subwoofer. Its slanted design maximizes the available air space. The mounting holes are cut with precision machinery, and the mounting depth is up to 11.25".

It is built in the USA from Grade "A" 3/4" MDF, which resists flexing so the box does not distort the woofer. Every joint is glued and stapled, and a layer of silicone is added to every seam. The enclosure uses an enhanced glue that keeps the carpet in place so it does not rip or tear. Connections are made through gold spring-loaded terminals.

Questions and answers

Is this box sealed or ported?
It is a sealed enclosure for one 12-inch subwoofer. Sealed boxes trade some output for tighter, more accurate bass than ported designs.
What subwoofer size fits it?
It is built for a single 12-inch subwoofer. Check your sub's mounting depth and cutout against the box before buying.
Does it come with wiring or a terminal cup?
No. The box is the enclosure itself; you supply the terminal cup, wire and mounting screws.
Will it fit a hatchback?
It is designed as a hatchback enclosure with a slanted front to save depth. Measure your cargo area against the box dimensions first.
Is it better than a cheap prefab box?
The 3/4-inch MDF and glued, stapled, silicon-sealed joints resist flex better than thin particle-board prefabs, which keeps bass cleaner.
Do I need to add polyfill?
Not required. Some owners add polyfill to sealed boxes to soften the response, but the box works as shipped.
