SRX Performance for a Fraction of the Price
Getting high performance doesn't always have to be difficult and expensive. The RE Audio SRI10D2 is a Sonic Exclusive item that brings subwoofer performance to the next level. At it's core, the SRi is a SRX subwoofer from RE Audio. That means big bass and solid power, even if the RMS only 300 watts. While RE Audio specifically rates this woofer at 300 watts, there are many applications in which this woofer is capable of handling far over 300 watts. Being an SRX woofer at its center, the RE Audio SRi has a different basket and a slightly different look than that SRX sub. However, the performance is the same. SRX performance with money left over. Thats what the SRi is all about.

Awesome subwoofer for the price!

This subwoofer is an awesome subwoofer to have for the price. For another subwoofer with the same specs and quality will easily be twice the price! Looks like the price is slowly going back up so you all better get one soon.

Best bang for your buck period!!!!

Just got these today and stuck them in a ported box 2 cubes ported to 33 hz. Had em turned down to break them in but the sound quality was great. Very crisp clean tone and they definitely showed potential to get low. Running two of these together to reach a 2 ohm load to amp. Re-makes a good product and these won't stay cheap very long so get yours while they last.

sri 10 D2ohm

I had a P3 12 in my crew cab 2 cubic foot box ported tuned to 33hz and a 250W Punch Amp it sounds good. Just got my RE SRi 10 D2ohm made a new face for my box. WOW sounds like I have a blow through cab w/2 12s Best sub for the price *****

amazing sound, amazing power handling, amazing price.

For 57 bucks, you cannot find and equivalent sub. i owned two Cerwin Vega vmax 15s (500 RMS each in a 5 cubic feet ported box), had to sell them since they wouldnt fit in my truck (old car was bigger). So I went with RE since I heard good things. Now its very hard for 2 10s in a sealed box to compare to even 1 15, but I don't miss much. That's a huge statement for something so small and so cheap. I wish I could put 50 stars on the value.

If your thinkin about it, get em!

PS- the only reason i gave 3 in look/design is because of the made in china sticker, and the pressed steel basket. my old cv's had a very nice quality basket, this one just looks cheap. but its got it where it counts.

3 of these are brutatly loud

This subwoofer is top for its worth. I bought three, and man do they bang. Running them at 3 ohms, and makes my truck rumble, great woofer, so far.

This is the most BANG for your buck hands down

I have a Alpine Type R and now this RE sub in my truck, I figured it would complement my awesome Type R, but it is actually just as loud if not louder than my Type R which I could not believe. A type R is over twice as much as the RE and this sounds just as good. I HIGHLY RECOMMEND THIS to any 1 wanting a awesome sub on a low budget. And I ran it at 300 watts 4 ohm load off a alpine amp i did not over power it to make it sound loud so im amazed.
