  1. 15" vented end tables!

    Ported Subwoofer Build Projects
    I should have taken more pictures of this build, but I did most of the assembly in a hurry one night after the rest of the family was in bed. Anyway, I had a full marty with a Dayton classic 15 that sounded amazing but I was suffering from massive room gain in one corner and the inability to...
  2. Small vented vs large vented Winisd question

    DIY Subwoofers - General Discussion
    I currently have a 12 cubic foot vented enclosure and now I am switching to two 4.5 cubic foot vented end table subs on each side of the couch. While modeling in Winisd, I am showing the same output and response curve (within one db)if I add an 8db boost at 20hz to the smaller box. I tweaked...

  4. Optimized impulse responce of subwoofer; Horn VS Vented box

    DIY Subwoofers - General Discussion
    Hi, I am investigating how to get best possible impulse response from a sub that will go all the way or close to 20Hz. Ideally I want to play 20Hz square-wave and it will still look as a square-wave when I measure it with a good microphone. My first approach was that a horn loudspeaker would be...
  5. Ultimax 15 vented is 180L too small

    DIY Subwoofers - General Discussion
    Ok so I've been looking at the Dayton UM15 to use as a single in a Ported box. I noticed that most designs recommend a largish box 10-14 cu ft for this driver and they do model well. I want to use this driver but got to keep WAF high so I modelled this driver in a 180 litre box with 400 W (using...

    I hope to get some brainstorming from you smarties. Lets get low and loud here... Just pulled the trigger on 2 Ultras. I would really like to put together the optimal vented system with the drivers, enclosures, and the space I'm putting them in. TC Sounds site shows a couple of different...
  10. winisd vented box volume; with woofer and port or without ?

    DIY Subwoofers - General Discussion
    when box volume is calculated or inputed into winisd is that the total volume of "free space" without woofer and vent, or total volume of the box with woofer and port ? I would guess that's the "free space" volume. so a box estimate of 6 cubic feet in winisd would need to be a total of inside...

  14. Vented 15" on-the-fly conversion to sealed Qtc .707

    DIY Subwoofers - General Discussion
    I've been thinking a lot about my current sub build (15" Dayton Quatro w/ 300W plate). It's plenty loud and my natural in-room response isn't particularly flat. I made that build with the best SPL/$ ratio in a "small" footprint. Clearly, the build is vented to maximize SPL, but is in a...
  15. Confused on the dimensions of the subwoofer vented case

    Ported Subwoofer Build Projects
    Been reading a lot the past few days about DIY subs. I am not sure whether a 12" or 15" subwoofer to choose. The 12" will require a smaller case, less than 3 cubic feet sq (in volume). I have used WinISD and for a vented 15" case, it gave me a height of over 3' (feet)! Not sure if that is...

    Single 8" in vented cabinet - Finished! About halfway done with this one - the box is together and the components work, so all that's left is the finishing. It's a single 8" Dayton QT210-4 in a 40-litre box, tuned at 35 hz. I'm working with ⅝" particle board. The optimal box size for this...

  19. IB vented to the outside of the house... ??

    DIY Subwoofers - General Discussion
    I have very little experience with IB but would eventually like to give it a go. Has anyone had any success venting an IB to the outside of the house? My fear would be the elements and the neighbors/cops. :bigsmile: Matt

    DIY Subwoofers - General Discussion
    Ok so I've been looking at this for almost a year now, and I just can't make up my mind what to build. I had a vented sub i wanted to build with 8 12" drivers tuned to 15hz. with a low pass filter at 30hz. The drivers have a FS of 32hz and 30mm excursion. So playing around with the parameters...
