Ported enclosure for Sundown X 6.5 SW

[Terranova 10+ year member]

Hello, I've been searching the web and forums for an enclosure for these subs but I can't find anything. Could someone please help me get a cut sheet for a .35cuft ported box tuned to 32hz for the Sundown X 6.5 SW? Space is not an issue either. I'd be more than happy to compensate. Thank you so much!

Length 20"

Width 10"

You'll have an awful time tuning that low in that little space, without port noise, without a passive radiator.

You might post maximum dimensions or other limits you have and someone will help. If nobody helps you tonight, PM me and I'll see what I can do.

Hello hispls, thank you for the reply. I want to say that I am completely open to suggestions. What do you think would be best? We will have two total subs in separate enclosures behind each seat with 325rms to each.

Can you do one box?

 

[Terranova 10+ year member]

We can do one box, we just wanted to try and do two boxes one on each side of the cab behind each seat (single cab pickup so space is limited) to keep the center available for whatever random items we want to put in the cab and not smash it behind the seats.

This is off the top of my head, so bare with me. Do 40x7.5x10 out of 3/4 mdf. Use a 4 inch pvc pipe and start at 44 inches. (Have to stick it out of the box a bit) trim to desired sound. Down fire the subs port to driver s or passenger's side. After all said and done you can set stuff on top of the box. I did one for tang band 6.5's in this manner and it sounded great

Thank you for the recommendation garychoffman, but 40 inches is huge and would take up more than half of the back storage area. We don't really want to do that. I may give that a try just to see how it sounds though.

With the port, it's going to be a large box

I found this enclosure from DD's website for use with the sw6.5 (Box Plans | DD Audio) would something like that work? Not sure what it's tuned at or the volume. It's nice because it's small.

If you want ported it has to be a larger box... If your concerned about storage space get a shell for your box or a cover

So what kind of dimensions would I be looking at to get a 32-34hz tune?

I believe DD tunes around 38. Not sure what the 6.5 calls for. I'm interested to see how these two small woofers would sound.
