    I will start with what i have and what i am looking for in a subwoofer. I currenly have a klipsh sw 310 sub, which is good till about 30hz and then it gives up the ghost. The room is the basement that is about 18 x 12 for the ht but the whole room is about 25 x 18 with 7ft ceilings. I would...

    Hi again ! Need to ask here again. I've switched countless of times between the 20 hz and the 15 hz modes on this great subwoofer. 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 -...

    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...

    iST Ltd. tells me that my two new 18's should be shipping today so I figured I might as well start my build thread! With some fantastic help from Graham (gperkins) as far as the design goes and a coworker helping with the build - I'm in the process of building two separate 9.3 cu ft...

    After all the talk, it is a go! I got finances lined up, just gotta dot T's and cross I's! hahaha..something like that. So do I: a: wall 4 21" Maelstrom-X's or b: wall 3 DTS10 Super Spuds? That's just for the car! For my home, 2 21" Maelstom-X's each in 128 cubes tuned to 15Hz with a 16"...

    Note: Final enclosure changed to 358L at 15Hz - Images below have been updated to reflect changes, except the Sketchup images. Same overall design. The purpose/goal for this build is 1) the need for some strong bass in a subwoofer deprived HT setup and 2) a huge learning experience...

    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...
