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 R2SD2-10 10" subwoofer has a peak power rating of 400 watts and a continuous RMS power rating of 200 watts giving you a comfortable amount of bass when installing one or some real deep bass when installing more than one. This shallow mount subwoofer is ideal for those with limited space but that still want a system that kicks. 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 R2SD2-10 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.

This sub is the answer!!

The following review is for R2SD2-10, which is a part of the bundle you are viewing.

I completely recommend this sub. It fit perfect under my 02 2500 superduty extended cab rear seat. I built a sealed box to spec and have amazing tight bass. I'm pushing 300watts rms to it and it takes it beautifully. Rockford fosgate knows how to built clear and durable speakers. Save your money on anything else as this price is perfect.

great for price

The following review is for R2SD2-10, which is a part of the bundle you are viewing.

had them over powered and ran them hard. never had any issues with them. great sound for a low profile sub.

had 2 mounted under seats of my jeep. had a lot of water contact (yes, i off road it), and damage from the seats themselves, but nothing that actually affected the output. made well.

R2D2 10"

The following review is for R2SD2-10, which is a part of the bundle you are viewing.

Installed a 10" R2D2 in a 2013 Toyota Tacoma behind the rear passenger seat in slightly modified shallow box after removing the storage bin. Used a Boss amp high level inputs off factory deck. What an improvement!! Just the right about of good clean bass for a small cab truck without breaking the bank. Better performance then expected on a shallow speaker and box. Also removed factory door speakers and replaced with JBL GTO's. Good clean sound and money left for gas!

It had to 'break in'

The following review is for R2SD2-10, which is a part of the bundle you are viewing.

this sub hits hard, and in a tight space. on a budget, I would get this subwoofer every time. due to confinements, I can only fit shallow mount subs in my truck, so I bought two of these, and DAYUM. at first they were quiet. but after a week or so, NEVERMIND, LOUD LOUD LOUD. very clean and punchy.

Great Price Quality

The following review is for R2SD2-10, which is a part of the bundle you are viewing.

I have one isobaric dual port pro-competition custom box in the trunk with one Rockford R2SD2-10 running at 2 OHM the Polk Audio AMP running this is bridged at 400 RMS. If you like bass this speaker is over the top, if done correctly! For the price you cannot beat the quality. If you’re a sound enthusiast as I am this speaker comes highly recommend for true listening comfort.
