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 RES series of car subwoofers to bring great bass in your car.

General Features:

  • 12" Dual 4 ohm REX Series Subwoofer
  • Power Handling:
    • RMS: 175 watts

RE Audio REX12

I own two of these subs, being driven by us Amp d 1500 sub amp in my 328i BMW and I get stopped all the time by people wanting to know what subs are hitting that hard and so clear! They are great, don't be afraid to try them. I promise, you want be disappointed!

Unimpressed

I love RE Audio but these subs actually did not impress me at all. Didn't last long in my set-up. Replaced them with nvx nsw 12s. For the price I guess they are okay. Slacking RE audio, slacking.

decent

sub is great, doesn't need a ton of power but, will take way more than the ratings show. the only con is that the lows aren't 100% of what i was looking for, however the mids are nuts!! all in all, great product

Very High Quality Sub for low power

Very nice low power sub sounded very good @115 watts 8ohms, I recently rewired it to 2ohms @over 300 watts rms and has no problems taking the power. I would recommend this sub to people who want good full clear bass you can feel, but not if you want shake to the neighborhood.

Great sub for below 100

It's the best sub for below 100 ..
Better than any entry level subs out there ..
installed it in my gf car ..
I've used before JL' , JBL , Rockford etc
accuracy as good as JL power as good as RF and JBL's..
tho I'm underpowering it with a small Hifonics 4 channel and running it on a 1.2 cubic feet sealed box I'm really happy with the sub ..
