Tinsel Lead Defects!!!

Got a bad batch of woofers. Hard black stuff on the leads right at the terminal created a weak point and broke the leads on all 3 woofers. Sounded good before they broke. I had to foot the shipping bill on the first return for something that was not my fault but Sonic took the other 2 back paid shipping after I proved my case. Overall they are a excellent woofer for cheap but I think they are cutting corners on the parts. Switched to Skar IVX 12's that have woven leads because that was pure hassle and a waste of time and money over silly tinsel leads. At least sow them in the spider. Also had cone slap and a felt material to deaden the sound.

Talk about sneaking up on ya'

Recommended by a friend, I bought a single dual voice coil SRX12" to replace a bulky box and a pair of 10's. Installed it in a custom box in a Chevy HHR.

Talk about sneaking up on ya' and kicking you in the head. This speaker is very VERY impressive. Hard deep bass notes, and crisp cannon-like kick drums. I have owned Kicker, Fosgate, and a few others and the RE really holds it's place in the ranks.

Awesome for the money !!

Bought these to replace a pair of JL subs I'd had for six years. (surrounds tore) I had read good things about these on the web and thought I'd give them a try. Best decision ever. I haven't metered them yet but they sound louder than the JLs. Lovin' em!

Super performance

I wanted a musical subwoofer that did not require a large enclosure.
The SRX12D4 fit with my plans. I matched it with a 500 watt amp and the results are stunning. Very musical, very accurate but when the volume is turned up the sound is powerful and in fact, it not only shakes the car it shakes you.
One 12" of this quality is all anyone needs and it is in a 1.2 cubic foot sealed enclosure. AWESOME

A good budget subwoofer

Pros: Lots of pleasing, tight, punchy, deep, loud bass.
Cons: None.

Disclaimer: this is my first ever subwoofer, so my points of reference are very limited.

My setup is the following. I run this one in a 1.15 cu. ft hatchback style sealed "Sonic Sub Box" that you can buy here from Sonicelectronix. Almost 1.5 pounds of polyfill were stuffed into the box to enhance the sound. The voice coils are wired in parallel and I am pushing 300watts to it using a 2ohm stable amplifier. I set the crossover point on my head unit at 80Hz, with a 24dB per octave slope. The box is in the trunk of a midsized car.

My impressions so far are very positive. I listen a little bit of everything, but for the most part all sorts of rock music (alternative, classic, american, latin, etc), and also some latin music, like regueton. In my opinion my setup (box type, crossover, etc) is near optimal for the kind of music I listen. This subwoofer playes tight deep loud bass without distortions. The bass is tight as opposed to being boomy. The volume can be very loud, yet at the same time soft on your ears. Bass guitars and other bass heavy instruments sound excellent. It's unbelievable how much music you miss without a subwoofer. Given the cost of under $150 (including the box and accessories), this product is a steal. All in all I am very pleased I went with a Re Audio instead of subwoofer bargain basement cheapies.

killer subs!!

I have used every sub u can think of I have a little moble electronic buss for th past 4 yrs. These SUBS POUND!!! They are getting 500 watts RMS each at 2 oms n sound GREAT!!!!!!! They replaced my orions n they blow them out th water. I think they can handle even more power..

Very Impressed

I picked up 3 of these and they slam. Have them in a custom box .90 cubes each sealed. For a "budget" sub I can tell you that this series will give you a good mix of SQ and SPL. You will easily pay more for some other brands to get the same performance. All 3 are powered by a Rockford Fosgate Power 1000bd @ 2.67 ohms and it gives them what they want. I heard on a forum somewhere to stay away from RE because these got outsourced to china but don't worry about that. The quality is solid with a beautiful chrome magnet. Out the box the suspension is very stiff. I think it will need a bit of a break in to get more excursion. This is a good buy and I recommend this sub.

stupid not to buy...

These things are ridiculous. I put four of d2s in a 6cuft box stuffed them down into a 95 Integra and they get down. Got them powered by a Memphis pr1000d @ 1 ohm. Best subs I've owned so far. No one expects them to be so loud. Wont buy anything but re from now on.
