Prime R2SD2-12

When you have no space for bass, our R2 12" shallow subwoofer can help satisfy your need for low frequency music. These drivers can fit in tight spaces due to an elevated motor structure that reduces speaker depth. Mica injected polypropylene cones make sure bass notes are clean and accurate. Stamp-cast baskets feature spider venting typically reserved for traditional depth mounted models to keep the motor cool! These shallow subwoofers are optimized for sealed enclosures.

great sub for pickup truck

Works great for the application wired the coils in series for the bridged output on my amp and the whole truck shakes, sounds crisp too

Disappointed...

I had 2 of these hooked up to a rockford fosgate p300 running at rms power and within a few hours, both subs were out of commision. the voice coil went out on one, and the other simply quit playing mid song. I was only listening to them at about half volume of my head unit. but for the time that it did work it sounded excellent. i just expected so much more from rockford fosgate.

pontoon sub

I needed something that would fit in my pontoon under a seat so it was covered. this did the job. got it powered from a old RF amp and it did the trick. nice little thump for the money

good truck sub

I installed 2 of these in a 99 chevy 2500 4 door they sound good for such a small sub. Depending on where and how you mout em ported/sealed depends on how they will sound in my case they added that extra low end fill i needed for great sound quailty.

Louder than expected

My first shallow mount sub and I was worried it wouldn’t sound near as good as a standard depth subwoofer. That wasn't the case at all!

Nice Modest Sub!!!

Purchased this Sub to put in my 09" Tundra. I've been running 300w @ 4 ohms to it four about a year in a sealed box. Sounds great for an entry level sub. Just remember, GOOD IS RELATIVE TO YOUR APPLICATION!!!!!. If you want bass below 40HZ this may no bet the sub for you. It has difficulty with most modern RAP music because of all of the 30Hz notes. However, this has been a good reliable sub and sounds great depending on the music your listening to and the environment you are putting it in!
