X15 box, SQL killer lows, hows my design look?

Recommended Posts

So I'm still wondering what type of box I should build for my X-15. I currently have a 3.45ft^3 tuned to 28hz via 6" aero port.. I want to get more output of the sub (I know I can) while retaining SQ. This is for a musical setup. I mainly listen to decaf, rap, pop and rock. I'd like to be able to move some more air also ;)
My choices: 4.2ft^3ish tuned to 28hz with a big L port. OR a 6th order with like 3.8ft^3 tuned to 28hz and second chamber 1.5ft^3 tuned to 70ish.
What do you guys think?
EDIT:
Forgot to mention that its being ran off of a CT Sounds AT1400.1

Without knowing the type of car or space limitations I would do 4 cubic feet tuned to ~ 33 via 2 6" aeros.

As much as I like the bandpass's I've built, In my opinion this is the time for a well built ported box, no need to go the bandpass direction.

Thanks for the input man! And my bad for not specifying the car. Its going into the trunk of my 2013 Accord Sedan Sport!

I got 30"~ of depth and 29" width and 17.5" height. I don't need a box design but I'm trying to figure out what's a good NET volume for this sub. It takes my CT 1400.1 easily too..

I'd also like to have killer lows too.

Keep in mind that port area, sealing off, even electrical etc play a role not just net volume, also tuning too low is not going to help loudness.

I see.. I'm on stock battery lol.. Going to be getting a D1200 up front and a xp2000 in back when I actually start redoing my setup. I plan on sealing off eventually. And I'm trying to get louder on lows rather.. It plays 40-50 fairly loud, well loud enough for me at least. I'll be shooting for a GOOD amount of port area too. I'm going to eventually get a 80PRS and fit it in my pocket under the factory radio, so that would help everything sound much cleaner too.

More port

Idd do 15x5

And tune it a bit higher like 30hz

Okay, I'll see what others say and then choose. I'm not in a rush to build the box cause I have to get some other stuff to the car done. I appreciate the input!

I'd tune a little higher than 28. But that's me.


Thanks alaskanzx5 I might just do that
I can recone a sub myself. About a year ago I took 2 12" power acoustic mofos and made one sub. I took the magnet and the motor off of one and j b welded it to the other motor and magnet. I had to wind my own voice coil so it would work. After I was done hooked up to 2 boss 5000w amps. And shattered my back and all my side windows

came to this thread to recommend soundqubed and ct sounds. OP goes with soundstream.

oh lawd.
