actual screen is 99 inches, im curently zoomed down to a 95ish immage. the projector is about 13.5' lense to screen.

there will be a layer of some (basically fiberglass duct board) material under parts, and some other (basically polyfill batting) material under others. havent settled on a source for the fabric.

here's some pictures of what ive been working on for the last forty forevers: http://www.richkraus.com/ht/ lots to do yet, but its at a nice "it's working" point right now (and i finally got the content loaded), so i thought i'd share.

chris white over at HTT was kind enough to adjust my figures (corrected for the RS meter) and turn them into a more readable plot: Some stats (corrected values): average = 67.9 std deviation = 3.28 thanks chris..

the strike drivers are still available :) theres a couple mm difrence in the xmax, and a couple other minor diffrences in the other T/S's there pretty close...

similar to the strikes. they are TC Sounds TC2+ 15"'s believe it or not i dont have excel installed on this machine. i think i may have it on the one in the other room, but my SO is doing homework on that one right now (do not disturb :) ) basically the graph is one HZ/one dB step per...

I left the response curve picture full size to preserve the detail, the link is below. method: burned sine tones from NCH generator, 1Hz steps, 1-85Hz. red line is 70dB/60Hz baseline. utilized radio shack analog dB meter (stock) played tones in 1 hz steps, starting at 85hz...

ben, its important to enphasize the "i wont need a big boxy, ugly, speaker in the room" pitch to soften the IB concept. or do what i have done both times (this is my second IB in as many homes), simply cut the hole and get it finished when she's not home :) understand this requires some degree...

ok, so you cant work IN the attic... is there enough volume to IB the shivas? i had a similar problem, enough room belly crawl to the location to run wire, but no room to work (it opens up to a larger space so the 10XVAS is no problem). result? surface mounting. just cut out a rectangle of...

im running a screen made of black out cloth pulled over a frame. performs pretty well for a near zero effort, $20 project.

that slatted door is going to resonate something fierce. as for firing at the celing, i have no idea..... :)

i think there are plenty of grill options that will work, but im guessing that your not getting many replys since i think the immage, stage, and tone of the speakers will be all but ruined with the fire-through-a-hole method im picturing. also, wouldnt that open the room to heat/ac containment...

yes. it doesn't have to be an attic :) i think obi has a rig (area behind built in RPTV) using a couple of 12's just about like what you describes (less the allmighty tumults :) )

andrew hit it on the head, you want to take a look at the space available to vent into (closet, attic etc....) and then calculate how many drivers that space will support (in terms of 4-10X vas) dont be afraid to cut a hole and vent in to the attic/basement. youll like the sound. its only...

dan you never cease to supprise with this sort of offer.
