I want to build a sub for my den/HT. I plan to use it for 70% HT, 30% music. The room is small (11' x 15' with 8' ceiling.) It has two door-size openings to the rest of the house that cannot be closed.
My current POS sub stands at the bottom of my stereo rack, in the front corner of the room. The space in there is ~2.5 cu. ft. There are two other locations that I could use to place a sub: In the back corner of the room (where I could touch it from where I sit) or as a coffee table in front of the sitting area (where I could set my feet on top of it.) For the back corner I could build a cube no larger than 22". For the coffee table I could go a little larger in volume, in a rectangular configuration. Either location would allow me more freedom of design, but the sub would be sitting real close to me, which apparently is not a good idea.
I'm thinking the best location is on the rack. I am somewhat worried about the vibration making my CD's and DVD's skip, but I don't see it happening in practice with my current sub.
That brings up the eternal question of sealed vs. ported. I like the fact that a ported configuration can be tuned for a flatter response, but I don't think such a small ported sub can be built (because of port length.) I can't consider PR because I can only use the front face of the sub to install a driver on. If ported is not possible, then sealed is my only alternative.
Here are my questions:
1) Is it reasonable to place a sub in a stereo rack?
2) Is there a driver that will model nicely into 2 - 2.5 cu.ft. box for a ported design? The port(s) probably can't go any longer than 12" to 15".
3) I have been primarily considering 12" drivers. Should I try 10" or even 8" to fit into the 2.5 cu. ft.?
4) Given my sub location choices, which one should I go with?
Thanks,
Sam
