    SVSound

When in 20 hz - I get the feeling of much more power, hair moving experience in certain movies - eg live free and die hard - bridge collapsing from harrier rockets -...

    Creative Sound Solutions
    My original decision thread is here. I was able to find more space by integrating my subwoofer, center channel, and entertainment stand into one. I also, decided on round ports instead of slotted because of the design complexities that arose with the center channel cut out. This is my...

    I finally got my UXL-18 and I wanted to do some modeling. Should I use the published .wdr file for the driver or what I measured on WT3? I did use the Mass method for my calculations. Here is the sub date from WT3----WIN ISD * Piston Diameter = 387.4 mm * f(s)= 20.86...

  10. Ditching my 15hz tune and looking for more slam. What tune is recommended?

    DIY Subwoofers - General Discussion
    I'm putting aside my 15hz tuned box for awhile and plan to build a box that will offer a bit more mid-bass "slam". I'd like for it to be a ported build. I have a 3500 cu. ft. room that opens up to a medium sized kitchen, which makes the room even bigger. And I've struggled with the loss of...
