  1. Ported Subwoofer Build Projects
    Good afternoon everyone. My brother in law and I built my box the other day and it is time to show the progress. The box is currently with my neighbor who owns a custom car shop and is putting a coat of bedliner on it. I must admit however that I am not too terribly proud of the workmanship...

    I have a customer with a CNC machine, that wants to pop out some cut parts for a Tempest-X2 slot port design. I've drawn this up to make it as simple as possible for someone to put together a killer sub, on a fairly tight budget. Design constraints were that it needed to fit on a single sheet...

    Hey guys I'm geting ready to build two slot ported cabinets for the 18in mal-x sub. I was told by a friend that for best overall performance I should tune the sub to 16-18hz and the cabinet size should be 10cuft interior volume max after deducting the sub and braceing. This is with 1450 watts...

    I designed this box and was hoping for some advise or opinions on it. I am pretty new to all this stuff but have done quite abit of reading the last couple weeks. I will get right to the pic, then explain more after. I want to build this box and locate it behind my DLP TV. The empty box...

    Hi Folks, I have started on my room within a room basement build featuring 3 layers of rock and GG and I am at the planning stages for ventilation. See my signature for the build thread. I plan on building soffits around the theater room as well as the sound lock room. Due to my low 7'3"...

    I am lacking in wisdom about ports and would like to know more. With a 20"H x 20"W x30"D and a 12 or 15 inch driver.........? Is it possible or even reasonable to do two slot ports, one above and one below the driver, having total depth 36" for each, and with a 15" driver the height of each...

    Hey guys, its tax time and my pending refund check has me itching for something low and loud! I am trying to decide between a round or slotted port for this sub I will be using an RLP-18 and EP2500/BFD setup. My main question is this: Is there a noticiable difference in sound quality between...

    Hi, I've two Tempest-X, DCX2496 and an EP2500 at my disposal. I have no idea if I'm going sealed or ported. Many people say "just build two sealed boxes, 8^3 each". I don't know. First, they'll be huge. Second, if I go ported, I'll get more output. I can add a subsonic (highpass) filter with the...

    This is for my TC2000 15" driver. I have built a LLT which i loved but the wife didn't. So in a moment of weakness i switched to a small sealed box and i don't like it nearly as much. I thought I would try a mid sized ported box and hopefully be done. Has anyone had good luck around 6-8 cut...

    How is one supposed to figure out an acceptable port speed in a rectangular port? Using collo's "flare it" program, it's easy to tell what ports are going to work, but with a slot port, it's hard to tell if a port will work or not..
