well, both drivers actually do well in sealed. you will happy with either. i had the obsedian 12 for a few days but i sold it locally becuase my box was screwed up. and i never had the proper power to it so i never saw its full potential

OA just because ive heard it in person and think its a great driver for the price

they're similar to exodus's stuff. looks almost like a home audio sub. they hold their own end.

i would just try the mach 5. just to be different. if you dont like it, then sell it.

I'd bang the mach 5, they are proven in HT to be some of the better for cheaper subs. They are working on a massive 21" sub at the moment as well.

I've had great experience with mach 5 but have never used OA. However the mach 5 will probably handle more power and looks to be more efficient

The older IXLs are ******. I think the newer ones are just split into two models, the sealed and ported versions. I got a 10" in my girlfriend's mustang on 1500 watts. 01limited has the original IXL 18" in his jeep.

Tinsels on the obsidian look a lot smaller than on the mach

so

so it could be a possible weak point....

People think you need huge cable for speaker wire, like 10 or even 8 gauge, but with the higher voltage outputted from your amplifier, line-loss is a much smaller problem than it is with the cabling carrying the 12volt power from the batt to the amp. In other words, Im sure the tinsel wire size on the Obsidians is perfectly fine.

i'm gonna wind my new subwoofer coils with Golden Gate Bridge support cable. 82 ought gauge ftw.

why would, out of all the companies, make their tinsel leads too small/short?

I've talked to the owner of Obsidian and he said the 12" would sound better than my SI MAG Claw v1 w/ v3 softpart recone. He has a good reputation but then again he is also the one selling the subwoofers...
