Anything But Entry Level

What RE Audio calls entry level is anything but entry level. Introducing the new REX series. It offers incredible output and distortion free sound you would come to expect from subs costing far more. REX car subwoofers are perfect for those just entering the car audio scene. Popular among the import and other cars where weight is important, these lightweight subwoofers are an excellent solution for performance vehicles that can’t have heavy subwoofers with large boxes. The mica filled poly cone is stiff and rigid, while the Santoprene rubber surround allows excellent response. Behind the cone is a high temperature 8-layer copper voice coil, a FEA optimized motor structure, and a conex spider that all assist in the linearity of the subwoofer when in use. With a RMS power handling of only 175 watts, these subwoofers do not require a large, powerful amplifier. However, like all of the RE Audio subwoofers, they are capable of accepting much more power then the recommended RMS. For an entry level subwoofer that is far beyond all the other entry-level subwoofers, trust the RE Audio REX series of car subwoofers to bring great bass in your car.

Great little sub.

This is a great little subwoofer. I needed a sub that would work well in a small enclosure under the rear seat of my '09 Titan. It is a perfect match to Sonic's Single 10" Angled Truck or Hatchback Box (10ANTCM).

This combination fits perfectly under my seat and sounds great. Nice tight, clean, accurate bass. I'm only using one and it fills out the bottom end of my system nicely. Won't rattle the windows of the cars next to me with just one, but I'm getting too old that kind of bass anyways. I'm more into sound quality than sound quantity these days. Give me clean highs, smooth mids, and accurate, unexaggerated bass and I'm a happy man. I no longer feel the need to wake the dead with my car stereo like I did when I was younger.

If you are wanting to win SPL competitions, get something else. Bottom line is, if you are looking for good clean bass that you can feel and enjoy, get this sub.

Great Sub

I have two in my truck, they sound extremely clean and the bass is nice. You cant beat the price and value of these subs, I recommend RE Audio.

Two is better than one!

I've been running one of these in my crew cab Titan under the rear seat for over a year now and it sounded good, but I wanted a little more since the Titan has such a big cab. I purchased another one of these and the identical box (see my previous review) and all I can say is WOW! Sounds amazing hooked up to a Rockford Fosgate two channel amp rated at 200 watts RMS x2 @ 2 Ohms. RF also under rates their amps; my birth sheet that come with the amp says it tested at 263 watts x2 @ 2 Ohms. These subs are only rated at 150 Watts RMS, but they are taking the power flawlessly with the gain on the amp set just under 1\2 way. Couldn't be happier with these subs. RE makes some good stuff and Sonic has the best prices you'll find anywhere!

it blew

Hey everyone. I had a bad experience with this sub. I had it for a week and it died on me. I've had plenty systems so I know it was not hooked up wrong. Box was good that I had just sub sucked. It sounded good for that week though. I guess you get what you pay for.

Perfect budget subwoofer

I've owned everything from competition SQ systems to mid range SPL systems to budget builds. Hands down, this is THE best budget subwoofer. I wish they made it in single voice coil for wiring purposes, but regardless, this is the perfect sub for a small, budget build. Adds all the lows you need without shaking the neighbor's windows. If you're looking for a $50 sub, this is it. I built an entire system for my jeep for $125, and I wouldn't change a thing about it. Perfect starter/adult system.

Nice Clean Bass

I was in shock with the bass with this budget priced subwoofer. I was playing around one day with my car and put just one of these in the trunk with a sealed box and it sounded just as good as 2 10" kicker comps in one ported box. Don't let the price fool you these are great subs.

Good Budget Sub

It is a good sub if you are on a budget and want some extra thump that factory speakers do not provide. Would buy again.

Great subwoofer!

Great 10" subwoofer, don't be fooled by its small size. Its an underrated subwoofer. More like 200-225 watts rms than 175. Had it powered with an MTX terminator 250/1 @2 ohms and it sounded quite loud and good sound quality as well. Would recommend this subwoofer for someone who wants some extra thump with their stereo. I bought this for my mother and she still thought it. Was too much thump for her. The box that it was in was the max ported box it should be put in. When i took it out of the car, i used it in my room and gave it the same power. Made a great computer system subwoofer as well.

Big BASS!

For the price I was not expecting much but these subs are amazing...They go really low and hit very hard. These subs are probably the best bang for your buck on sonic right now. I would recommend these to anyone
