I have gotten spousal approval to build a sub (to replace the melamine coated dbx-15 I have now). The room is approx. 13' x 26' x 8' w/popcorn ceiling, with only two standard door-size entryways (on one of the 26' walls) and a full masonry fireplace (on the opposite 26' wall). Intended use for the sub is probably 50/50 music/HT. Size is a factor here... SWMBO will not tolerate anything over 20"w x 20"d x 24"h. Budget max. is $600 (for the entire project, including finish, which will be furniture grade... hopefully).
Other environmental considerations are my 2 year old, who will poke at any front firing sub and will likely stuff shoes into any front firing ports. All of my kids are small and go to bed early... so bone jarring, seismic-concussion inducing bass is problematic. My L/R mains are Polk Monitors (5-1/4" 2-ways about 15 years old) and the matching CS 100 center. Surrounds are Atlantic Technologies 3.5" dipoles.
I've downloaded UniBox and WinISD Pro. I've looked at sealed and vented alignments for several 12" subs (Shiva-X, CSS SD12, GR Research SW-12B, Peerless XXLS 12) to the point I have a headache. I've even drawn up several models in Sketchup. I have an appointment next Thursday with my therapist for my evolving OCB disorder (spawned by this sub project).
I've done so much modeling at this point that I've lost perspective.:gah: And now, I'm wondering if I shouldn't go to a 15" sub (assuming that a 15" sub will be more efficient with low frequencies at low volume than a comparable 12").
Ladies and Gentlemen, I need focus.
