RE Audio SEX Subwoofers

RE Audio’s SEX Line of subwoofers redefines high performance and value. These subwoofers are placed in the middle of RE Audio’s full line-up, and can handle high power output around 600 watts RMS! These SEX Subwoofers are the perfect addition to any trunk!

These impressive subwoofers are built into a cast aluminum basket, and their triple stacked magnet drivers work off of a 3” 4-layer aluminum voice coil. This allows for quick bass response, and clearly outputs for deep bass in the lower frequency range. With an FEA optimized motor structure, the SEX subwoofer lineup maintains tight bass response and allows the subwoofer full control over all types of music.

Each one of these RE Audio SEX Subwoofer can handle 600 watts RMS of continuous power, no matter the size! These competitively priced subwoofers are an excellent complement to any audio system, and will provide you with that clean, hard hitting bass you’re looking for.

On a budget considering the price of shipping and installing these are near best you can get for the price. Bought a pair of them powered with a Hifonics Brutus brz1200 wired down to 1ohm and they slam so hard. People hear it before I even drive into the street. Everytime the bass drops it makes me smile and think how its worth every single cent.

It was either have a choice between this here re sex, audioque sd or the americanbass tnt line. After trying hard to see if anybody had any of them I located a pair of tnt 15s, they forsure sound good play lows good and everything, i will say i only heard 1 of these sexs but just the 1 sound really really nice, played lows way better than what it thought it would for a 600rms sub, this thing forsure handle more than 600rms, it might burn up at 1k tho, for about 360 a pair with 3 year warrenty its a good deal, yes they make some money but the only reason im buying them is becuase i know Sonic is loyal to their warranty's. All the stuff on these are decent, nothing like a high leval sub but i know sombody who had an se model for 4 years. The surround is good, the spiders seem good, the coils are quilty, the motor has a nice charge to it and the metal is good quality, the only thing im worried about are the leads, if u wanna run around 1200 rms id find something else, i mean it might take it for a little. If your thinking about a solid 15 and want to have clean low bass, i would say this is a good choice. 2 of these in a box with clean power will sound pretty darn good. And yes these are louder than sundown sa series subs too, i will be reviewing these again in couple days ill give you as much info as i can.

I had a 15" Alpine type-r before this. SQ wise this sub wins hands down. In spl the alpine type-r has it by a little bit. Overall i like this better than the type-r.

I bought this sub to put in my fiance's 05 Xterra, hooked up to a hiphonics hfi1000.1d 750rms @ 2ohm on a stock battery and alternator. The sub is very responsive, and hits hard. Very good for a budget build but I think I will buy the sxx model next time.
