18''sx Re subwoofer

I just got one RE Audio SX18 one an RE Audio 4000watt amp and let me tell you it pounds so hard it makes the stuff in my house fall off the walls overall I like it .

Better than I thought

A friend owed me money so he gave me this sx18 brand new and a 6cu ft ported and I put it on a hifonics amp pushin 1200rms in my 94 suburban. It makes me breathe like crap. It was more than I expected from this sub and the sound quality is awsome from zz top. To oldies to hard hitting rap I REALLY recomend ths sub or any RE subs. The reviews speak for them selves and Sonic is the best site to buy from.

THUMPING!

I have had several 18" subs from different manufacturers all running 1250 watts rms @ 2 ohms and this sub hits much harder than any sub I have owned. I could recommend this sub to anybody looking for high performance at a great price. Don't settle with a crappy sub buy RE Audio the first time. Shipped in a plywood frame to keep it safe during shipping which was a shock to see a company give the extra effort. LOVE THIS SUB.

AMAZING!

This sub is my first 18 and all I can say is WOW. Its really loud and the sound quality is good. Just make sure you put it in a proper box, and by proper I mean large. Really, the only bad thing about buying this awesome sub from Sonic is the 7-14 days to get it shipped. I believe this is because Sonic is direct with RE Audio and they are manufactured for each order.
