I just finished up with my install: 2) 12" D2 GCONS in a DC-Creations Sealed Enclosure, all installed in a 2012 Volkswagen GLI running from the factory fender audio system to a LC2i LOC and Kicker ZX1000.1 Amp w/ KnuKonceptz Kolossus Flex 0 ga kit.

GCONS:

Visually: I placed my order and received the speakers about 25-30 days later, just like the guys @ SSA said. Between the heavy foam surround, to the huge magnet, to the frame, they look SICK. Looks wise, I can't complain, the build quality seems to be great; real heavy duty shit here. When I bought my kicker amp from the car audio shop around the block, the guy I dealt with asked what I was running for subs. So I showed him... His eyes light up and he says, "SSA... never heard.. WOW! Those look SERIOUS!"

DC Creations:

Build Quality: I ordered a stage-one sealed enclosure with the flush mounting option, built to the max dimensions of my vehicle. The enclosure is around 1.3 - 1.35 ft^3 per speaker. Received it in the expected time-frame with no issues. Build quality is awesome and I really liked the way the guys at DC wired up the box for me; 2 runs of heavy gauge wiring shrink tubed right to the terminals. It was basically plug and play. The enclosure was built like a brick shit house compared to one my old prefabbed enclosures. No comparison there.

Fitment: The GCONS slipped right into the flush mount face, wired right up, VERY EASY. It was perfect in all aspects. HIGHLY RECOMMENDED

Performance:

Overall the installation went well; getting all the LC2i and ZX1000.1 adjustments were a pain but I finally have then fine-tuned and I couldn't be happier. This was my first sealed enclosure so I really wasn't expecting much in the area of loudness (compared to my Kicker L7s in a ported enclosure), especially running off the factory head-unit. Honestly - I'm impressed in all aspects of their performance (Enclosure and Subs). They get low, they get high, they're punchy and most importantly, they're really clean and tight; I don't understand why it took me this long to go sealed. Loudness - Unless you're competing, I can't see ever needing any more SPL than this. My car has a sunglass compartment that pops down from the headliner. When I turn up the volume - it flies open and my sunglasses fall on the floor... Every time.... Its really impressive. The rear-view mirror doesn't move around in circles like I've seen in some SPL videos but it shakes a LOT -the same goes for my side-view mirrors. A friend of mine runs a pair of 12" Alpine Type-Rs @ 600-700W each in a sealed enclosure; All I'll say is this - every time I see him now, he asks me to trade. The Type-Rs get pretty damn hot, pretty damn quickly. I'm not sure that I'd feel comfortable running them hard for any longer than 15-20 minutes at a clip.

Last night I took a 2-3 hour road-trip running my GCONS pretty damn hard (safely of course). I felt the cones out of curiosity - BARELY WARM after 3 hours in a SEALED BOX @ 550-600W Each.

Overall: Although they were only around 200 bucks each, I'm not sure that I'd call the GCON a budget subwoofer. The only thing budget is the price. I can only imagine how loud these would be in a ported enclosure from DC-Creations. 2 THUMBS UP AND HIGHLY RECOMMENDED!

Will try to get some GoPro videos up this weekend.

Nice little review there !

Pics and videos to come.
