  1. how loud are IB subs through the rest of house

    IB - Infinite Baffle Subwoofer Build Projects
    I'm thinking about building 2x18 IB subs (probably start with one manifold, then move to 2). My media room is on the 2nd floor, has attic above and on three sides of the room, faces an exterior wall which is about 10-15ft from the neighbor. Will an IB sub resound through the whole house? can...
  2. Line versus opposed ceiling mount IB

    IB - Infinite Baffle Subwoofer Build Projects
    I'm going to build a ceiling mounted IB subwoofer. I (believe I) have 22" between ceiling joists. The speakers I'm going to use are two Fi IB318's. A 2-in-a-line array is (barely) possible and would require twice as big a hole in the ceiling, and somewhat simpler construction. The alternative is...
  3. IB Dayton 12” reference series

    IB - Infinite Baffle Subwoofer Build Projects
    Hi All! I’m new to the forum, and I’ve been contemplating building an IB for some time. I currently have two Dayton Audio 12” reference subwoofers in sealed enclosures that I built about three years ago. They’ve definitely treated me well. I recently moved into a new house with a nice large...
  4. Single amp to power front 3 and an IB?

    Home Theater Receivers | Processors | Amps
    Hello, As a neat solution I am looking at a custom 5 channel power amp to power the front 3 speakers in my setup, and an IB which I will install. The amp would be a 5 x 300 watt power amp. This gives me 2 channels with which to power the IB with. Does anyone have any thoughts as to if they...
  5. 2 -si 15" D2s in an IB

    IB - Infinite Baffle Subwoofer Build Projects
    I was told directly by SI this is possible -- convert it into an IB . How do you determine the box size for them? Two options for placement = living room wall and off the garage or living room floor and under neath the floor. If I do the garage I would do one box like this - My concern...
  6. IB sub questions for new media room

    IB - Infinite Baffle Subwoofer Build Projects
    I am in the research phase of my media room project... Definitely thinking about IB subs since I like the idea quite a bit. But have some questions: 1. I assume ideal placements are the same as for any other sub? Four corners, four center walls, or two centered on the sides? Obviously subject...
  7. IB installation question on wall bracing

    IB - Infinite Baffle Subwoofer Build Projects
    Hello all. I have a 15'x20' theater room with a vaulted ceiling and dormer windows. Due to the way the interior was finished, I have two fully enclosed (drywalled) areas in the front of the theater room, one on the left wall, and one on the right wall (symmetric) that I want to use for an IB...

    IB - Infinite Baffle Subwoofer Build Projects
    I have had my 4 x 18" FI sub in place for 4 years now. Here is the build thread: It is the Christmas Build: http://www.hometheatershack.com/forums/ib-infinite-baffle-subwoofer-build-projects/63366-christmas-build.html Nobody has been able to answer this question and I have not seen an...
  9. Will IB work for me?

    IB - Infinite Baffle Subwoofer Build Projects
    Hello all, long time lurker first time poster here. I'll get straight to the point and see what you guys think about my situation. I've been interested in IB for almost 10 yrs but never had the cahunas to go forward with it. So I ended up with three SVS 20-39 pci's that were great for what they...
  10. Fanless Amplifier for my IB Sub

    Subwoofer Amps | High Pass Filters
    My Carvin HD1800 croaked. There's a loud hum. I think it means that something came unsoldered. I'd like to replace it. It lived in the closet because of the fan noise, and I'd rather have one without a fan. Here's my existing configuration. The IB sub has four 18" drivers. Each driver is...
  11. Fireplace IB Build

    IB - Infinite Baffle Subwoofer Build Projects
    Why did I build this? For the exact same reason George Mallory climbed Mt. Everest, "Because it's there." That and maybe because of all the internet know-it-alls who told me it wouldn't work. "it's" in this case being a nice big old brick fireplace smack dab between in the middle between my...
  12. Can I I.B. ?

    IB - Infinite Baffle Subwoofer Build Projects
    I have a cement shelf that wraps my theater room. My dimensions are 16ft x 22ft x 10ft. The cement shelf 46" high and 18" deep. If I place a drop ceiling they will be 8ft. So from the shelf to the ceiling is approx. 4ft. If I build a baffle wall for my front speakers I can add another 18"...
  13. IB questions drivers, amps etc..

    IB - Infinite Baffle Subwoofer Build Projects
    So I am about to build my first IB. The space for the back-wave that is approx. 150cuft. I am wondering what my best options are for size and number of drivers? I was thinking 2 15's such as the PE IB385-8. I understand the FI 15" gets a lot of love but I can't justify the cost difference unless...

  16. Is the IB385-8 okay for home theater?

    IB - Infinite Baffle Subwoofer Build Projects
    I found a couple of the Dayton Audio IB385-8 15" Infinite Baffle Subwoofer on Craigslist, $75 each. Are these okay for a home theater subwoofer? If I get them, do I just do WinISD as usual? I saw lots of folks putting them in walls as subs, but I didn't see a lot of subs on the floor. Does...

    IB - Infinite Baffle Subwoofer Build Projects
    I am starting my first IB build in my living room. I do not have a dedicated theater room at the moment, so we are turning our living room into our family entertainment zone.

    So i have 4 AE 15s in two manifolds powered with BASH 500 for each pair. I took some SPL readings relative to Frequency with volume set to 50 on my receiver,and was curious if anyone has advice on smoothing the response or maybe sound treatment. Ironically i ran an audessey calibration as my...

  20. Go w/Bad IB Sub Location or Traditional Sub?

    IB - Infinite Baffle Subwoofer Build Projects
    I was originally going to go with an IB sub but upon getting my furniture I realized the sub placement would be pretty much next to the recliner instead of out in front of it. So I can either go with the side location, or move it more rearward. Or I could go with a traditional subwoofer in the...
