Opinions on a box for a DD 2512

I'm surprised how well these drivers play at high excursion by the way. I might venture into more DD in the future myself, if I get the time. Great choice of drivers I must say. //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

 
Kid? really, kid? You're going to straight up insult me and then try to turn this into "oh let's focus on the op". That's exactly what I was trying to do. And challenge your expertise. Sorry, I don't know who you are. Are you special because of your website with cookie cutter designs? Funny, I did not see many builds. We are in very different parts of the country so I obviously don't know you or your work and you obviously don't know me. Does that make either of us wrong or right? Absolutely not. Like I said, my comment was directed towards whoever recommended 33hz tuning for this sub. Somehow you took offense to that and decided it would be a good idea to insult me.
Oh, and I love how you base audible performance on physical appeal. Lol

 
nevermind, I just reread the op's first post and saw he was looking to play up to 70hz with authority. LA crx actually had the best recommendation for you then. 2.5 will have to steep of a roll off.
Lastly, I viewed your stuff as well, you do good work by the way. Keep it up!

 
Don't get your ******* in a bunch, I was more or less referring to whoever said tune to 33hz. But feel free to show us some enclosures you've designed or built that prove your advice is the best.

really, p*anties was edited?
I have to say I have built some Award winning boxes in my day, but I have never designed or built a box design quite as impressive as the one Mobile Enclosures had done for me. It's amazing that the usable frequency is very broad. When I say broad, I mean BROAD! I recently was able to get a hold of a Termlab and really get into tuning my system, and I was able to get an almost completely flat response from 29 hz to 120 hz at 120 db. It was really quite amazing. 3 db drop off at 28 hz and a 2 db dropoff at 122 hz. I will have to say the speaker in the box is not the one it was designed for either, its a JL Audio 10" 0w1v or something (super Cheap) 150 watts, and the one it's designed for is the new SSA Icon 10" which I am waiting on to come out, but it's 1250 watts. I expect to get a flat response up to 132 to 137 db and maybe max out spl at about 140. This is with one 10"! This is the enclosure

P*anties? I want to know which Mod decided to put that on the ban list. Pretty Lame

 
Thanks to all for their input. I'll likely drop the volume down to the 2.2-2.3 range & shoot for close to 36hz. It'll prob be a few days before I get time to start working on the enclosure. I might be able to start arround this comming Thurs, if not it'll be the following week.

 
I've used the 2500 pretty much any dd extensively.2 tuned to 36 is perfect for a nice musical ground pounder..

just give it 25"^2 of port area..
in my car that will only play 25hz and down and will be choked off bad.

it's impossible to ignore the car completely and recommend boxes

 
this is what I would use if I were you OP

That's a nice looking design, but realistically might be more complex than I'd want to attempt. Also just eyeballing it, I'm not sure it'd fit in the back of my pathfinder.
 
DD 2512 in a small SUV you say???

I have a hell of a 4th order design that is sick w/ that sub in small SUV's.

Its a very easy build also. Its about the same size as an average 2.5cuft net vented box.
