Design Questions for 12" SSA XCON in ~2.5 Cubic Ft @28-30Hz Enclos

[azlnick 1]

Vehicle : 2002 Toyota Avalon XLS
Location in the vehicle: Trunk with rear armrest access port
Space available (Length x Width x Height): 22"x42"x16"
Subwoofer make and model: SSA XCON 12 D1
Number of Subwoofers: 1 for now.
Type of Port (Kerfed, Slot, Aero, etc.): Kerfed would be optimal, Slot if not kerf.
What type of music do you like?: Electronic, Drum n Bass, Classic Rock, Alternative, Rap, Hip-Hop, R&B.
Is your goal SPL or Everyday Music?: Everyday Music geared towards SQ
Tuning Freq (Hz): 28-30 or so
Volume : 2.5-3.0
Questions:

1. I plan on only giving about 600-1200w by a Crescendo BC2000D, should I have the volume of the box be closer to 3.0 to maximize efficiency?

2. As far as tuning goes, I would love to enjoy the lows and compliment my Image Dynamics CXS62v2 front stage. Is @28hz low enough? Should I port even a bit higher to make sure I have the SPL I am expecting from the XCON?

3. I plan on doing double baffle and flush-mounting the sub, do I need any bracing? How does kerfing compare to slot in terms of output, SQ, and is it worth the effort?

 

I'd love to hear your in-depth explanations so I can know more about fabrication, box building, and audio in general. Thanks in advance guys!

I'd build the box closest to the highest optimal that ssa recommends.

 

If I were you I would tune a little higher like around 32hz. The music you listen to really doesn't go all that low. I listen to decaf and I'm tuned to 32hz and it gets it all.

 

I would probably put some bracing in there since it's a really wide box.

I would go with 3 cuft. tuning can be 28 to 32hz.

I've seen people suggesting to use threaded rods for internal bracing, how would I do this? Still wondering if kerfing is worth it.

Anyone else want to take a stab at it?
