Well now that he has the subs, i figured i would post this up on here. I built the box a little over a month ago, but he just now got the subs from OA, so he's wiring everything up today and finally getting it playing. I'll post up all the pictures i have of the box build and what it looks like now. He wanted a low end ground pounder, and i gave him just that.


Box specs:
40 cubes NET
560 sq in of port
32 hz tuning FTW!

8 Obsidian Audio 18's
10 Powerware AGM batteries
300 amp alt
2 sets of Focal mids and highs (i have a feeling he's going to need more)

Don't think I've ever seen a setup in an astro that wasn't a wall. Should be interesting. I would have used threaded rod personally, though.

Wanted to keep cost down. Ran stress and strain analysis on this style of bracing and the numbers came out looking good, so i went with the truss style bracing. Some people might comment on a single baffle, but with t-nuts there won't ever be a problem.

Blake (owner) had talked to Hank about his box. We decided since blakes van had a little more room (length wise) and less room width wise, we would do 8 instead of 9.

Blake uploaded some good pictures he took with his Nikon. After he put everything in he said it was turning the van into jelly. The sliding side door looked like it was going to fall off. And the only amp he has in now is 1 AQ 2200! Can't wait until he gets 3 more 2200's and shows those subs some real power. Hopefully we'll get a video in the next day or 2.

He says it is, even though the subs are only getting about 150-200 watts a piece right now.

If you don't have a video by the wego show in Tulsa next month tell him to swing by and we can get a video.

When and where's that show going to be at in Tulsa? I might have to attend that. And I think he's going to be going to a lot of shows next year. This is a demo beast. Wasn't made for the meter, but i'm starting to think it's going to put up a pretty **** good number. Haha.

7th - 4th annual Julian's Customs Car Show - Altus Community Center - Altus, OK

21st - 3rd Annual Signature Sunday Car Show - Tulsa Convention Center - Tulsa, OK


Those are the next shows here in OK. Both will be double point USACi shows. I know the points for the show on the 21st will be going towards the 2013 season. I'm not sure about the 7th since that is the weekend of finals.

Little teaser video for you guys. Subs are seeing MAYBE 50 watts a piece, yet the whole van is flexing. Couldn't turn it up since he was in his neighborhood, but more videos to come.

So how much is each of those subs?

bigbud747
09-16-2012, 08:55 PM
I believe they were $159 for the preorder and you can buy them for $189 now that the preorder is over. I would email them for pricing though. But i'm pretty sure it's $189 for an 18.

Eh, subs are getting about 50 watts a piece in that video. Wait until they have a 2 10k's on them.

Blake did a little experimenting today. Won't know results for another couple of days (when he gets a Sampson). Just inverting the subs lowered tuning 3 hz and raised box volume by 2 cubic feet.

I'd of probably built it out of birch, would of been hell of a lot lighter and just as strong.

The customer just bought a Sampson which is currently installed in the van. He said its just as loud if not louder than his previous setup (4th order with 6 15's doing a 155). The next step is to weld bracing to the roof and attach wood to it. His roof is cancelling out low frequencies at high volumes. Hopefully getting some hd video next weekend. But overall its an absolute beast.

sadly thats not that true any more lol well at least for 13 layer baltic russian birch audio fanatics did a test on it and i think it was just a few tenths lighter but i agree on strenth mdf is cheap as **** and damages easy birch may cheap small pieces but never cracks
