Our Product Research Team
At Crutchfield, you'll get detailed, accurate information that's hard to find elsewhere.
That's because we have our own in-house Product Research team — they open the box,
verify contents, check the owner's manual, and record dimensions, features and specs.
We stay on top of new products and technologies to help people make informed choices.

Features
Overview: The Rockford Fosgate Prime R2D2-10 is a 10-inch
subwoofer with dual 2Ω voice coils. The sub features a StampCast steel
frame, quick-release compression terminals, and a mica injected polypropylene
cone. An anodized aluminum voice coil former and spider venting help keep the
subwoofer cool.
Steel Basket: The R2D2-10 subwoofer features a StampCast steel
basket for added rigidity.
Compression Terminals: The Prime R2D2-10 features spring post
terminals which accommodate speaker wire up to 12 gauge.
CEA-2031 Compliant: Power handling on the Rockford Fosgate
Prime R2D2-10 subwoofer conforms to CEA-2031 industry standards. This means the
subwoofer has the capacity to handle power under continuous demand, not
instantaneous power handling, that over time, can damage voice coils.
Enclosure Compatibility
Sealed Box: Rockford recommends a sealed enclosure with an
optimum internal volume of 0.59 cubic feet (from 0.5 to 0.75 cubic feet is
acceptable). Sealed enclosures provide the most control over a woofer, will
handle a lot of power, and provide accurate sonic reproduction, making them
suitable to all types of music.
Ported Box: Rockford recommends a ported enclosure with an
internal volume of 1.4 cubic feet using one 4" diameter x 13" long
port; this yields a tuning frequency of 43 Hz. Ported (or vented) enclosures
typically provide better overall efficiency than sealed so they are suitable
for use with smaller amplifiers, giving you more bass output from less power.
However, this efficiency comes at the expense of very low frequency output
(below 40Hz).
