  1. I made a wicked loud T-line for a single 12" so I don't know, do you. It was really big, though.
  2. okey but remote viewing into some random person's computer is so completely sketch lol
  3. If your head unit EQ only effects door speakers and not RCA output then yeah. Buy yourself a scope though, if you're that concerned. They are really inexpensive now and there are plenty that are plenty good under $100. I think there's not really a way to accurately tune with just a volt meter... it won't tell you whether your waves are coming out cleanly. Just my opinion though since I tend to tune by ear and my shit is probably distorting lol
  4. 18" Ported Box Tuned at 22Hz Single 12" Box Tuned at 24Hz Dual 6.5" Box Ported 40Hz I also have an H-Frame for some GRS 12" drivers I want to upload. It works surprisingly well and makes a ton of bass from $30 drivers.

    Really sus? Among us

  6. Winter pisses me off. I just hate it. I can't stay warm outside unless I wear so many layers that it becomes a task to go outside at all. On the bright side, I get to turn all my computers on and do science to heat my room with BOINC, and Monero mining.
  7. I put 4 tennis balls between my bed and my cab to stop the back of the cab flexing so much and rattling. IDK if you will get higher SPL from that, but you will get less rattle. Logically, the SPL would go up because every time your panels flex out and in, that means the energy was lost doing so. It's probably not much, though? Maybe not even noticeable on the meter. JacobViral had a cool build a while ago trying to get 150dB out of a single 10, then a single 12 in a huge ratio 4th order band pass. He went to extreme lengths for the deebeez. You may be able to pick up some interesting SPL pointers from his videos and what he did, but probably not a ton that's applicable to a daily. He went extreme
  8. 40hz tuning is yucky, good for SPL competing I think only. I have a 10 cube (ish) box tuned at 33 or 34Hz design I could send to you. Port area is rather lower than some people would want, but that makes the box smaller. The design is slightly basic, but rather easy to build. That size box and that tuning make that box a burp box IMO. I wouldn't want to listen to it. Tuning lower brings the thunder
  9. I've got to build the pictured box before I decide what to do with the design. It's for GRS 12sw-4 drivers isobaric. The baffle is meant to hold the two drivers and then be bolted into the enclosure. Two ports on each side of the driver. It's supposed to be sort of a horn as well for projecting sound out doors. I definitely have not modeled it in Hornresp or anything else besides WinISD and I don't know how to. The 12sw-4, I think, has the same motor/magnet as the 10sw-4 yet more cone area so it sort of sucks because it still needs an uber huge enclosure to hit those very low notes. This box is tuned to 23Hz and 4 cubes volume. Here's a design I released. It's for two 12" drivers ~2.5 cubes ~33Hz tuning.
  10. I understand that thing better now. I see what it does. Just seemed like some scam nonsense when I first looked into it. Also, it just didn't seem to do anything in this guy's set up. His install had some little problems that made it confusing. First off was that his head unit was set to high pass the subs at like 80Hz and it took me a minute to figure that out. Then, plainly, I had no idea what the Epicenter was or what it was doing
  11. Made this box design up today for a couple of the 10SW-4 subwoofers after seeing Toid's video of these drivers. Made for isobaric loading. Has a horn situation on it. 2.84 cubes and 25.7Hz tuning before the basket displacement. F3 around 21Hz.
  12. Simple Transmission Line For Lower Power 12 Inch Subwoofers
  13. Box Design for 2 Sundown ZV5 18's 14.25 cubes after displacement and 29-30Hz tuning 48Wx28Dx24H inch external dimensions.
  14. We got the Epicenter figured out and I learned more about it. It actually works for what it's for, just hard to get a bearing on exactly what it does which is annoying for me. Oh well. Two more boxes for your bass wumpers to burr some womps or something. Single 18" 7 cubes, 34Hz. Fits in older Ford Explorers. The early 2000's ones. https://youtu.be/DXxOXha7Hgc Quad Kicker 12" box... or any other 12" subs that it's right for. 9.95 cu. ft. 33Hz. Fits older Escalade. https://youtu.be/o88oK5NN7Tk My GW-124 in my truck and yes it is extremely sloppy, no I do not care. https://www.youtube.com/watch?v=k4edvSXAU9Y
