    I plan on running them in two separate 3 cubic foot enclosures, down firing. The room is about 20x25 and is an open living room / kitchen area. I plan on running them each off a channel of a Sunfire Cinema Grand so each one will be getting [email protected] I'll be using Audyssey XT32 to EQ them...

    I have read so much I can't figure it out. I have Winisd, and I enter all the stuff. I see the box it suggests, but then I look at real projects and none of the enclosures look like what Winisd or any of the plans online look like. Finally, I keep reading about making a 2-4^3 box. Can I just...

    Hello everyone, I am attempting to build my first sub and am not sure which direction to start. I have a open concept home and the viewing area is in the living room which is open to the rest of the house. I think my budget doesn't allow for a sealed system so I am thinking either ported or...

    I happen to have a 20 foot long vacant room behind my home theater and have always wanted to build a large sub for movies.. I have been thinking..... Couldn't I have a truly huge sub and only expose part of it to the home theater room? So it would take up about 0 space in my home theater but...

    This is what im thinking its all 1" birch and im overbuilding this? 3" front baffle 2" every where else with 3 1" braces inside As of right now the box almost takes up 2 full 4x8 sheets so it should weight in around 150lbs
  6. Ported Subwoofer Build Projects
    After doing REW sweeps of before the port and after, I realized I was tuned much lower than I thought. Thinking 990 cubic feet realizing 1003 cubic feet (closet door closed, opened it's more like 1040 cubic feet and 4Hz tuning) and from 9Hz to 5Hz, I can't have a title that I can't correct. I...
  7. Ported Subwoofer Build Projects
    I have decided to take Thomas-W's advice and build a manifold on my door to house (4) Fi IB3 18's on the top and make 2 slot ports on the bottom out of the rectangles already there. The door is 1.25" thick, I will make a template/face of the entire door adding .75" to the thickness. I'll make a...

    Finally got one of my 4 subs up and running. I dont have pics of the subs mounted in the box yet. Man google sketchup is misleading as far as scale. LOL

    I am looking for a sub design that will be one cubic foot outside dimensions. I realize that it won't play exceptionally low, but it is for a relative who won't tolerate a big box. I would like whatever bass it produces to be quality bass, not mud. Any ideas?

    Is it possible? I got swallowed up by the new fad a while back, but I am only concerned with 35Hz on down. I know these tapped horns are amazing, but I don't like how they perform better as you get higher in the FR. If I build one large enough to go low enough, this might just be my thing...

    Just wanted to share my 1st HT sub build using one of Kevin's Tempest X2 drivers. Outside dimensions are 20.75h x 29w x 19.5d Here is the box already underway. I'm gluing in the .5 inch plywood as braces. View from the bottom (downward firing box) I was just going to screw in the driver...

    Area where the sub will go measures 47.5" W x 34.5" H x 24"D. Plan to double ply all walls with .75" mdf plus another ply of .75" birch on the face. So the interal measurements should be 44.5"W x 31.5" H x 20.25" D. The encloser will be built into a nuc like a cabinet base with some sort of...

    Here are some build pics from the build I did. I'll have to update them because I've since painted the inside of the ports red, and cleaned them up to not look dusty lol. Each box with driver is 220lbs and I can max out my spl meter with over 126db + at seating pos. Everyone that has heard them...

    I have two 3 cubic foot sealed enclosures. One has a Tumult II. The other is empty. (No missile silos for me :innocent:) Anyone have a Tumult in excellent condition they want to sell? If not, what US made driver would you guys recommend to go with the Tumult. I am using a BFD, a BASSIS...
