  1. Dayton Ultimax 15 and 18 Sono

    Ported Subwoofer Build Projects
    I seem to have no real luck with the speaker design programs, can someone post what the sonosub charts and numbers would be for the 15" and the new 18" UM Dayton speakers would look like? Oh, with 500 watts if that matters.
  2. Sono

    DIY Subwoofers - General Discussion
    Hey guys! I was wondering a couple things. Have any of you used dynamat for building an enclosure, to add damping to the enclosure itself?(sub, or speakers). Or would this be wasted due to the mostly good damping effects of MDF? (Assuming MDF as the most popular material) And also, anyone know...

  5. Critique a Mach5 IXL Sono design ? Some questions

    Ported Subwoofer Build Projects
    I'm playing around with Sonosub.exe and winISD and have come up with some measurements. A few questions: First: The area after(lower) the tune frequency, should I put much thought into this ? I was under the impression that below the tune frequency, distortion rises quickly. So for example...

    DIY Subwoofers - General Discussion
    I know this has been discussed several times before...but I never really saw a strong conclusion on this. I know that some sonosubs need to be almost floor to ceiling in height. The calculator even tells you how much room you need to stand it up. However if you have a sono sub that is almost...

    I have 2 700 liter sono subs using Fi Q18's and an EP2500. Detailed more in the Fi forum. In my fight (or quest) to get audyssey to play nice, I tried plugging the ports by wrapping beach towels tightly and stuffing them in the ports. It helped Audyssey to "play" better (that is a discussion...

    DIY Subwoofers - General Discussion
    The person I spoke with at PP said they had not done any flow testing with their 6" PP VS an 8" sono port-(straight or with roundover). Any one here had direct exprerience with one over the other? Things get a little close behind the driver if I use the 8" (box is 24" deep and 22" high and...

    Dual Q18's in 700l Sonotubes tuned to 12.8Hz 30" Sonotubes cut to 67" and 8.4" ports cut to 31.25". Well, it all started innocently enough. I found that moving my living room HT stuff to a more dedicated basement HT enviroment lost a lot of bass. Research brought me here. I enjoy doing DIY...
