    Not done, but running, want to see?

    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.

    new IB response curve, uncorrected, no EQ

    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..

    new IB response curve, uncorrected, no EQ

    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...

    new IB response curve, uncorrected, no EQ

    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...

    IB or Ported Dual Shivas

    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...

    IB or Ported Dual Shivas

    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...

    Putting a Tempest in a closet?

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

    Need some info on building an in-wall.

    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...

    Mini IB?

    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 :) )

    someone suggested infinite baffle - need details

    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...

    Bramha 10 for HTuse?

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

    Question concerning backside of IB......

    if its isnt already id insulate your garage door. if its the bare metal type it will resonate something fierce and will likley be more annoying than the bass.

    Dual 1804 IB finally taking shape!

    thanks james, good to read ya :) nothing really special in regards to the IB, some extra insuation in the attic, and the manifold will be secrured to basically a solid block wall, but other than that, no. the house should be done in another month-6 weeks, and im as excited as i could...

    Dual 1804 IB finally taking shape!

    i dont know their retail origin, i bought them *ahem* "already broken in" (used) from a member over at another forum. the price was right and the cones are so purdy, so i had to give them a try....

    Dual 1804 IB finally taking shape!

    james you pimp daddy you. lovin the $ in the middle.... i think theres a select few that regularly get to see both sides of their IB keep that IB faith :) !!!!!!! im going to use these lowly tc sounds 15's in my new room, but if they dont cut it im heading the 1804 route too....

    290 pounds, two 15" woofers, and 113 dB at 20 Hz

    as long as there is a ballence between the size of the motor and the size of the cone, there is no reason an 18 couldnt be as "fast" as a 12. FWIW, HERE is a chart of common woofers if you were trying to compare value for woofers in an IB.

    Infinite Baffle Subwoofer - Wow!!!

    see thomas, we keep tellin these guys- and yet their supprised when it performs. :) i dont think ive heard an IB gone bad. its simple to build, inexpensive; and for those with the guts to cut "the hole", a path to bass nirvana.

    what is the defintion of "do it yourself"

    unless you are planning to go out and forge metal, fabricate wire, resisters, caps, mill heat sinks, ets.. its all sourced from somewhere at some point. i supose some would consider buying off the shelf components and integrating them into a room a DIY home theater. (it did require some...

    Dumb question, but how much diff. between a SA-WM40 and a Shiva?

    leap of faith? I upgraded form a first gen NHT 10" sub to my 2 tempest IB. If you build a shiva based sub and are unhappy (really unlikley) you can always take it appart and re sell the driver and amp. I cut a hole in the wall to facilitate my sub. kinda hard to sell that :) The shiva is...
