R2D4-10 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 R2D4-10 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 R2D4-10 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 sound

Best sub I've used. Have tried infinity, alpine, crunch, and some off brands in the same price range. This one sounds way better. Deeper and louder. Very tight, crisp. In a 1.1 cu. Box. 500 watt amp

Crisp & Breathtaking Bass

Paired up with my Boss R1100M and Belva MDFS10, this makes the best single sub setup for the money! Bass is perfect and not overwhelming like my 2 12s were. Very smooth bass. 100% recommend. This is in my daily driven car and I've been running it for a while. Rockford Fosgate

Very good sub

These subs hit nice with the right power also in a ported box. You can max these out too with sound. Nice and gives you the sound quality you want.

Good Entry Level Sub

I always build my boxes myself never buy prefabs. I built a box sealed at .8 and the sub sounded really well for $50. Rockford did a good job with this one. Definitely fills up a 1998 mustang. I just ran one and it's lasted well for two years now run on a 200 watt amp. I would buy again if on a budget.

F150 Supercrew

I was looking to put some bass into the sound system I was building for the truck. As I have gotten older I was wanting a good SQ set up. I chose this sub for its value, wattage handling, & the dvc. I built the box and got it powered using a channel amp and it has delivered. I cannot comment on the durability as I have only had it a month but so far so good.

nice loud sub

I have one of these in a custom ported box tuned at 40hz powered by a boss 1100 watt amp. Im giving it 250w rms and it sounds great at lower volumes. When I really crank it up I can hear it outside the truck and it rattles body panels, but it dont have as nice sound quality at higher volumes. Overall its a good sub and the price is great.

rockford fosgate r2d4- 10

My brother bought me this sub for my birthday, he has dual 12 inch hifonics running 800 watts a piece. My single 10 inch can keep up with his dual 12's if you are looking for good reliable bass I would say that the r2d4 is your best bet.

Good Value

This sub sounds great. After roughly 15-20 hours of break in time it really starts to shine. It's in the back of my crew cab Tundra in a passive box tuned to 34 Hz with a Dayton Audio 10" passive radiator. It's feeding off of a RF 300.1 and after breaking it in it keeps up with the amps power. I have bottomed it out before during a torture test but the voicecoil definitely handled every bit. The duel voicecoil is nice too for extra wiring options.
