Having just finished 2 si18' marty cubes I find myself wanting more POWER. I currently have one sub in the front left and one right rear of my room. I did a sub crawl and the best place I found so far would be a nearfield on the left side wall behind my couch. My problem is I just got my attic blasted with 4" of insulation and I don't want to go up there to run wires down the wall. (hidden beams, me having no balance = bad idea). I might do some testing again tonight to see how moving my rear sub closet up would work.
I though if I used a wireless RCA to send the signal,then I throw an amp there and have the subs directly behind me. That may work*.
I was going to get 2 more si118's but wondered how they would compare to 4 or 8 1262 12"'s in a ported box. If I can get enough output form the extra subs I could forget the nearfield and throw another one up front, in the back or even the side wall as that walls all open and I could easily run a cable.
Up front the biggest I could go is 2' H x 3' W x 2' deep. Put each sub on either side of the center. (how I had my SI's originally, but moved them apart to get better dispersion). I could also go where the sub currently is, but I am limited to a 2'x2' foot print and could go pretty high if needed.
If I built something for behind the couch I could go about 30"H x 4' W x 2' Deep.
If I put something on the right side of the wall facing the couch I could go even bigger but probably not deepe than 2'.
*Down side to the nearfield would be having the sub amp next to my head and the WAF would go down a bunch. She is pretty cool with most stuff, but I don't want to go to crazy. My woodworking skills leave something to be desired so I wouldn't be able to pull of a nice looking "back of couch" end table that housed the amp.
Rooms about 3,400 cubic ft.
What would you do for subs and where would you put them?
