2 DC Level 4 15" Enclosure Ideas

[Samwatts22 10+ year member]

I just bought 2 DC level 4 15"s and I am having trouble with deciding what type of enclosure to put them in. I'm pretty set on 3.5-4 cuft per sub at a 30-32 hz tuning. Not sure on the following

Aero port vs. Slot port

Subs up/port rear vs. subs up ports up

I'll be running them in a Dodge Magnum SXT so space is not limited to 3.5 per.

any ideas or suggestions are greatly appreciated!

* Dual 2 ohm, running off 2 seperate xtx5000.1 Re Audio Mono's ( non Bridgable sadly.) Amps are already owned so please dont ream me on how it turned out i bought with the intension of running 1 xxx 15 and 2 dc level 2 12"s but it didnt work out to be that way so now on to the box ideas please and thanks!!

I think for those subs stick to around 3-3.5 cubes net per, tuned around 32. Sub up, port back. Slot vs Aero is up to you.

Any Pro's and cons on running slot vs. aero on 15"s?

and thanks I think i will be keeping it at 3.5 and 32-31Hz

Aero ports are allegedly more efficient for their cross sectional area, and have the advantage that if you do not like the tuning you can quickly change them out. Slot ports allow for part of the port being part of the enclosure itself, thus serving dual purpose, done properly either one will satisfy. Personally, I have always done slot, but I am partial to kerfing, and its just the way "I've always done it"

Thanks big help i think i am going to go with the slot port. Hopefully add some rigidity to my enclosure
