View Full Version : Opinions on a box for a DD 2512

I recently bought a 2512 to play around with. Just wanted to get some opinions on what to go with enclosure wise. I will probably be using a 6" pvc tube for the port & I'll flare out the ends myself. This will be going in a '03 pathfinder.

The full-size recommended enclosure DD lists is 2.5ft^3. I'm looking for for a nice musical- sounding enclosure, this will never be metered. I was also thinking of tuning somewhat high, like 37-40hz. I listen to all types of music, a lot of rock, metal,punk, alt, house, prog. house but not really much rap or anything chopped/ screwed or anything. Being able to hit up to 70hz or so with some authority wouldn't **** me off.

So.. What do you guys think about enclosure sizes & tuning? Should I go a bit smaller than 2.5? could I go larger without getting "boomy"? Can tuning to 37-40hz work out ok or should I just plan on tuning lower? This is the 1st DD I've owned.

Why would you wanna tune that high?

Why So Cereal?
10-21-2011, 09:34 PM
yea I'd say tune about 33hz at the highest

Why would you wanna tune that high? Well DD recommends tuning around 40 till the drivers are broken in well. I'm also kinda looking for more "punch" than just low end output. This sub is still pretty tight. Kinda wanted to see how it did tuned a bit higher. I can always change it up or whatever, I just got this to play around with.

If that's the case, then a 36Hz tuning would be best. It has a higher Q, so a lower tuning than 37-40 would be better in this case. Hope that helps.

I do, yes. Others, idk. Personal preference is a ***** sometimes when looking for what is best for "you". But proper operation with diverse passband efficiency, yes...36Hz is my recommendation.

I tuned mine at 38 and wish I would have went lower... I'll try it @ 35-36ish with the aero-type port, if I feel it isn't low enough I'll just build a slot-ported box tuned lower.

it will be very hard to get the port dd's need with areo's, try for 4 4'' ports to driver side and sub facing back
2-2.5 tuned right around 35hz

curious responses here. 2.5 with a 6" aero tuned at 38-39 will get you the results your looking for. It will play fairly low but still have a lot of "kick". I have a lot of hands on experience with these subs, not just spewing out random generalized bs.

2510 in 1.8cf tuned to 37.5hz with 30sq" of port. Did nice for me off 1200 or so watts. Ripped the spiders though by my fault droped below tuning and there they went.

I have a lot of hands on experience with these subs, not just spewing out random generalized bs. Well these responses are pretty much what I expected. I'll try to go as low as I can with the 6" aero. I doubt I can go much lower than 36ish (looking to go port back). I can always go higher easily, If I need to go lower I'll slot port it & go as low as need be. Thanks very much for the responses, they are appreciated.

Random? Generalized? May I ask who you believe is random and generalized? I find it surprising to hear someone say that.

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.

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.

Nobody is upset kid. Calm down,lol. Anyhow, you shouldn't have to challenge my expertise if you know who I am. :). Anyhow, if you're done trying to contest, let us focus on the OP. Its his thread...respect it.

OP, let us know how you make out! I'm excited for you. Hope you find your key tuning for your preference and have enough insight with all of the recommendations here now! Plenty to go by,lol.

I was just gonna run it off an AQ750.1 unless I decide to buy something to drive it a bit harder. To Buck, IDK i've heard these can sound pretty good in the proper enclosure. I run 2 JL W1v2 12's (sound better than you might think) in a sealed SQ type setup normally. I bought the DD for a project to mess around building a box for & test & such.

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.

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..

2-2.25ft^3 with a mid 30's tuning worked great in the couple of instances that I got to play with the 2512.

You're amusing. Well, your comment was fugged up and I speak my mind. could have been like everyone else and just made a recommendation for him, but you had to insult someone else in the process. Doesn't feel so good does it....to be insulted? Me, idc. Say what you want to me. I've been through more important discussions before,lol. And heard much worse. So, like I said, please concentrate on the topic. :)

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.

in my car that will only play 25hz and down and will be choked off bad.

http://i123.photobucket.com/albums/o296/wenn_du_weinst/durango12abcsig4.png 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.
