R2D2-10 10" Prime Series Subwoofer

Eliminate Entry Level and Go Straight to Prime

Sonic Electronix is now carrying the brand new line of Rockford Fosgate Prime Series Car Audio Subwoofers. The R2D2-10 10" subwoofer has a peak power rating of 500 watts and a continuous RMS power rating of 250 watts. This makes this an ideal subwoofer for anyone looking to add some bass to their car audio system. Equipped with anodized aluminum voice coil formers for extreme heat dissipation, will allow this sub to perform at optimum level during long hard hitting sessions. Perfect for sealed or ported enclosures the R2D2-10 is the way to go when looking for Prime performance with an affordable price tag.

Anodized Aluminum Voice Coil Former

Anodized Aluminum Voice Coil Former

By using an anodized aluminum voice coil former on their subwoofers, Rockford Fosgate is able to dissipate heat from the voice coil more efficiently. A hot voice coil can melt the adhesive bonds, which will lead to eventual subwoofer failure. The aluminum voice coil former acts as a heat-sink to dissipate thermal build-up on the voice coil cool during high SPL conditions.

CEA-2031 Rockford Fosgate Subwoofers

Conforms to CEA-2031

Rockford Fosgate has built this subwoofer to conform to the CEA-2031 loudspeaker power handling industry standards. This means that you can trust the subwoofer to have the capacity to safely handle the continuous (RMS) power rating. Having a CEA-2031 power handling is important when matching a subwoofer to an amplifier because the power ratings are accurate.

Rockford Fosgate Stitched Tinsel Leads

Stitched Tinsel Leads

To improve the reliability and performance by reducing fatigue and possible shorting, Rockford Fosgate has stitched the tinsel leads to the spider. The multipoint periodic stitching lead wires reduce the mass of the tinsel leads to spread the stress over a greater area. This improves the reliability and performance of the subwoofer.

Great subs

I've had these running for several months now in an enclosed box and they're excellent. The response range is very good even with very low frequencies. I would recommend them to anyone looking for a solid addition to their car stereo.

I have 2 of these subs enclosed in my rear deck of my 2000 Cadillac Deville. Running bridged off the rear channel of my Kenwood 4channel amp. These subs do exactly what I need them to do. I use them primarily for when I don't have my big bass on. (3 JL Audio W6's running off my Hifonics Brutuz 2400) & they get the job done. They have a desent bass drop giving more bass than the original factory 8" sub. I would recommed these subs but it be based on the application you would be using them for.

Rockford Fosgate R2D2-10

This is a great sub series by RF. The R2 series are well worth the money. The 10" which I own hits as hard a the JL 12w1 that I replaced. My set up is the R2D2-10 paired with a MB Quart RA400.2 amp ran off my factory Mazda radio via OEM integration by PAC. Subs pounds amp looks great. Highly recommend to anyone

Great Speakers

I have had these speakers for about six months now, and all I can say is wow! These are really nice speakers. I have them in a regular cab Tacoma in a ported box (box is crap) but these speakers sound great. They will not blow your eardrums out, but who needs that anyways? Hope for a new box soon. Give them a couple weeks to break in good before you rate them. I was quick to say they were not good, but after a couple weeks, they sounded awesome!! Thanks Sonic for a great transaction!!

Bang For Your Buck

I had this sub in my 1999 Silverado under the back seat, and it was ran by a RFP200-2, and let me tell you, in the cab...sounded amazing. What I liked most about it, was that I could listen to it loud, but it wouldn't carry and shake the **** out of my truck. Definitely worth the money.

Hits Hard, budget price, stellar sound.

I ran 2 of these in a sealed box wired for a 2 ohm load and all I can say is WOW! RF includes great box screws and even includes a good quality hex driver bit. Great subs on any budget.

Awesome speaker!

I have 2 of these 10" currently in my 05 f250 supercab, running off of 900 watts rms each. They handle every bit of the power and abuse! I've been installing for 22 years and have never heard a 10" hit like these. The lows sound like 12's and the mid to high range is ridiculous. I would recommend them to anyone! You can't go wrong with them. You get superior sound at a superior price!

Good entry level sub

This isn't the most incredible sub in the world, but for the money it would be hard to beat. I have bought 3 of them now and I am very satisfied. I would buy another if the need arose for one in this price range. I like how they included quality fasteners as well as a hex driver bit too.

One Rocking Rockford

I currently have my sub in a sealed box with an independent 350w amp for it and it jams I thinks its one of the best subwoofers in its price range with good tone more so focused on the extremes but that's what you want right? For a piece of equipment this well made at the price it is I plan on trying to get another.
