Box for HDS315

[dangercdv]

I have to HDS215s, in a box thats way to small for them, and I can tell. Its been long enough, im going to upgrade to the HDS315, just get a single one, and put it in a new box in the back seat of my car... but looking on ebay im trying to find the best box I can for it, and im not sure what to pick based on volume and port area.

I emailed soundqubed with 3 options (3cubes, 3.5, and 4 all with different ports) and he said any of them would of worked. So out of these 3 (or another box for $200 or less) what is the BEST option for the HDS315?

(2.95 cubes tuned to 31hz, slot port)

Also, personally I like the first one the best based on looks, but im afraid those two 3 inch ports wont be enough, but I could be wrong.

Two 3" ports isn't enough port area for most 10" subs, stay far far away from that box.

Generally I'd say to stay away from ebay sub boxes, but the second two do look decently constructed. The 4 cube box will get you more output around tuning, but either would work.

Alright, thank you. I am leaning towards that 4 cubic foot box now.

Would there be anything wrong with this box?

Just wondering cause its same price but free shipping. Look like enough port area?

[Triticum Agricolam]

Well the first box is built out of birch plywood, which I consider superior to MDF, but it doesn't make a huge difference. My concern with the last box is port area. They don't say what it is. You could ask them what the port dimensions are and then let us know. Then we would be able to give you a better answer.

What amp are you going to be running?

[dangercdv]

im asking now about port area, but you should be able to calculate it, or pretty close with the deminsions and knowing its 4.0cubes of airspace. But im asking in case, also my amp is a hifonics 1700 rms, but I dont push it very hard.

[Triticum Agricolam]

Yeah, just as long as they can tell you the width and height of the port, that's all we need to know to calculate port area.

still waiting on a responce but how do you know the other box has enough port area? http://www.ebay.com/itm/SOUNDQUBED-HDC315-15-Hand-Crafted-Birch-Ported-Subwoofer-Enclosure-/281889670394?hash=item41a1ef04fa:g:To4AAOSw5IJWdTzu

Obvisouly it looks bigger...but is it worth spending an extra $40 to have the larger port area? I have to measure my back seat for that box also cause I may have it facing up if its too deep.

The one on the link has 16x3 = 48 square inches and it's enough port area, definitely is worth to have proper port area, but if you made it yourself it would be way cheaper and better customized to your vehicle. It would also be useful if you told us what's your vehicle.

I have tried in the past to make them myself, and several tries all lead to bad builds, plus im away from home in college now and have no space or time to do that. Also, its going in the back seat of a mustang convertible.
