    I have been reading these forums forever it seems and I am looking to put two ACI SV-12's inside my stage build. At 16w x 15h x 120long I can get the 466l enclosure with bracing WinISD recommends. I can either face the driver to the front with two 4" ports to the sides or face the drivers...

    I recently built 2 SDX 15s in 9.3 cu.ft tuned to 15 hz and based on their size have been wondering.... I have setup these drivers using the RS digital meter and the cal file, only to find some massive peaks, so I picked up the 1124p. Tamed the peaks and am extremely happy with what I have got...

    I would like to know how I can use WinISD to model a dual chamber ported box. I would like to know if it is better and how it is better than just a regular ported box. I was going to use this (http://www.diysubwoofers.org/prt/dual_chamber.htm) as the basis of box. Is this correct?

    Well it has been a long journey to get my sub built but I am nearing completion. I started this build in this thread but as I shared my center channel build here so I thought you might like to see my sub-woofer. All I have to do is my surrounds now...

    I just finished a ported sub, 3cu. @ 21hz and lined the walls with 2in fiberglass. I am used to using poly-fill. Do I need to also place poly-fill (lightly) in the enclosure? I have read in an older speaker design book that one can stretch a piece of carpet pad across the back of your driver...

    If you saw my other thread on this topic (link) you would know that I'm trying to help my parents install a 5.1 system since they are renovating their house. I was having trouble with sub design/placement options because they are very picky customers. I was inspired by joorge's post in my...

    I'm working on a build of two CSS SDX15 subwoofer boxes for my almost-finished home theater. This is my first time building a speaker box. My previous sub was a Dayton Titanic 10" kit sub with a pre-assembled cabinet. I don't have much woodworking experience so I was a little nervous about...

    Ported enclosure advice needed! I just pulled the trigger on a pair of CSS SDX15 subwoofers and a Behringer EP2500. The plan is to use them in two ~9-10 cubic foot boxes with an 17-18hz tune. Usage is 90% home theater/video games. The boxes will sit in the front of the room near the screen...

    I have been on another forum for a while but I'm not getting much input, so I thought I'd hang out here, and if it warrants it, offer my project to be added to the database for anyone else looking at this driver and design. I chose an AV15-X from Acoustic Elegance and I already have an EP2500...

    I am playing with WinISD and I think I found my box size and tuning frequency but wanted feedback before I build. I was planning on going with a 16 cubic foot "453.10 liters". Does anyone have any experience with a ported box this size and tuning freq?:scratchhead: Oh and the port I was planning...

    I had some speakers laying around the house and decided to build a absolute bottom dollar budget sub out of them for fun, and because I couldn't find any other use for them. They were Goldwood GW-1244, which aren't even actually subwoofers but I digress. I managed to build one and get it up and...

    I realise this is mainly for home audio but Mike P is a genius with Sub's so here we go... Currently have 2 x 12" KFC-xw1225db in a 80 lt box tuned to 25 hz in a Custom VY commodore. I wanted to take away the box and turn in into an IB setup? Spec's for Sub are as follow... Z. 4+4 ohms Re...

    I'm helping a friend from work build a subwoofer for his home theater system. He said he was going to go to best buy and buy one for $300, so I convinced him we could build a much much better unit for about the same price. He has his own wood shop so the cabinet is going to be a piece of cake...

    This is a 16.5 cu/ft sonotube tuned to 16.5hz with an 8" sonotube port. I am using two Maelstrom-X subs for drivers. They are 24" sono tubes. This is my first sono build. The pics are of my wife standing next to the tubes, and a few build pics. This is the extent of day one. I am trying to...

    I was sitting in my room last night watching a movie and all of the sudden I had a question. Why not port your IB enclosures? Sounds crazy and impossible, right? But take my room for example. My HT room is in the basement. Underneath the stairs is basically unusable space (other than storage)...

    I have finally been able to start my second sub build, and it is long overdue. First of all, I have to thank Sonny and the Shack, and Bob and Creative Sound Solutions for the driver, via this past summer's contest thread. I had some early plans, which I mostly stuck to, and the enclosure is a...

    I see most of the subs designed here are tuned below 20hz. Whats the purpose for tuning below audible frequencies?

    About four months ago I built a test box(23.5" cubed-sealed) for my new Tempest-X and EP2500. Then I broke my wrist and was casted. Just after getting my cast off I was jumped and robbed and broke two ribs. I am finally in good enough shape to build my ported enclosure. Want to use .75" MDF...

    I am starting this thread to highlight some of my new build. The driver will be a Mach 5 MJ-18m. The enclosure is being constructed with 3/4 fir plywood. It has 3 - 4" ports, two in the front and one in the back. The glue blocks are approximately 1" x1" oak stringers. The front baffle is...
