DD2510a enclosure help

[AWD PSI 10+ year member]

What I really want is to do a FG enclosure in the corner of my trunk. The DD website lists box specs for a ported enclosure of 1.5 cu ft. I think I could get that but it's the port area and length (24 sq in & 23 in) I might have trouble with. I would really just like to do a sealed enclosure and keep it simple and small and out of the way. I'm not looking for anything crazy and I won't be maxing out the sub. I'm thinking I have the wrong sub for what I want to accomplish but I'd like to use it if I can make it work.

Well sealed would be okay, but your EBP for that 10" is approx 68. Usually any sub with an EBP over 50 is best suited in a vented enclosure. Looks like most anyone on here can help yah with the box design. I can walk yah through it with pics of stuff I have done. A smooth finish in a corner can be achieved. I can walk you through the enclosure, glass, prep for finish and finish if yah like.

What Fq are you wanting to tune at? 23" will get you at a tuning fq of just under 30Hz. Do you have a goal in mind?

In my test my 2510 sounded better above the 35hz range.

At 35Hz you can run a 4" Dia. port at 15.5" long and be just fine. I can calculate the flare on the port as well if you like.

If your interestedL:

a 5" @ 35Hz will need to be 25" long

a 3" @ 35Hz will only need to be 8" long

a 2" @ 35Hz will only need to be 3.14" long

If you wanna play with some numbers, here is how I put it into my TI-84 (just fill in the blanks with your info):

((14630000*(D/2)*(D/2))/((Fb*Fb*Vb*1728)-(1463*(D/2))))

I used 1.5 cu ft as the desired enclosure space and 35Hz as the tuning Fq

If you want to run a slot port you can go:

12" deep (into the enclosure), 1" high and 14" long or:

8" deep, 1" high, and 9.5" long or

4" deep, 2" high, and 9.5" long or

Again this is based upon a 1.5 cu ft enclosure tuned @ 35Hz.

Thanks, I could always use pointers from those that have glassed before. This will be my first attempt. I'm going to do a small little fg project first to get used to working with the stuff and then try my trunk box. I'd hate to just jump in and ruin a big project like this. I've been reading up over at fiberglassforums.com and I'm ready to give it a shot.

I really don't have any specifics in mind as far as tuning goes, I don't want something a boomy as a bandpass, just some nice bass that rounds out my system. Looking at your other posts it looks like you confirmed my suspicions that I will need a bigger box than I want, at least vented. This is the enclosure I have in mind that I want to base my project around, Evo 8 sub box. It looks like I only have about 1 cu ft to play with based on their design, I could maybe squeeze a little more out of it since I'm doing a one off and they probably took low volume mass production into account with theirs.

1 Cube it is:

At 35Hz you can run a 3" Dia. port at 13.25" long and be just fine. I can calculate the flare on the port as well if you like.

If your interestedL:

a 2" @ 35Hz will only need to be 5.5" long

a 1" @ 35Hz will only need to be 1" long

If you wanna play with some numbers, here is how I put it into my TI-84 (just fill in the blanks with your info):

((14630000*(D/2)*(D/2))/((Fb*Fb*Vb*1728)-(1463*(D/2))))

I used 1 cu ft as the desired enclosure space and 35Hz as the tuning Fq

If you want to run a slot port you can go:

7" deep (into the enclosure), 1" high and 13.25" long or:

6" deep, 1" high, and 11" long or

5" deep, 1" high, and 9.15" long or

4" deep, 1" high, and 7.15" long or

3" deep, 1" high, and 5.17" long or

2" deep, 1" high, and 3.25" long

Again this is based upon a 1 cu ft enclosure tuned @ 35Hz.

I will get some pics of stuff I tossed together. Glassing can be expensive when it comes to materials. If you could get me some pics of the area you wasnt the enclosure, the max distance from the sides of the car you are willing to go, as well assome measurements, that would be very helpful. Are you wanting to do a total fg enclosure? or a fleece over frame enclosure? Basically build the box for the sub, but frame out the ring for the basket mount then work fleese over it for a nicer look, then fleece over the enclosure to "Blend" it into the car.

Thank you for taking the time to post all this info for me. I appreciate it! If I'm reading your posts right it looks like I can make a port almost any size needed to fit? I'm going to focus on the 1 cu ft size measurements because I believe that will be the size realistically achievable. I like the smaller size ports for space concerns. So a 2" dia port 5.5" long and a 1"dia port 1" long both tuned at 35Hz will yeild the same results?

I guess it would be a full fg enclosure. I want to make some test pieces first, I'll look around the garage for a project to get working with fiberglass so I don't ruin my box attempt. I was thinking I will tape off the area in the trunk and lay mdf for the floor piece and then fiberglass to box area in the trunk and use the fleece over the floating ring to make the front. I have visions of covering the front in carbon fiber after I make the fg box to get a cool carbon look to go with some other pieces in the car. I will probably just do carpet though and maybe revisit it later with the carbon. this is pretty much what I want to do : This is the same car and space I want to use.

Below in an unorganized order is a set of door pods I made for a 3-way comp set.

And to give you an idea of how to get that fleece over the enclosure you are thinking of building:

Last enclosure I built that was actually INSIDE of the vehicle. It was made, and glasses to fit perfectly. I included some pics of things to "play" with when carpeting
