sure thing!


did a few layers of spraypaint today, will put some stuff from a can on for the final coat(s) got a red top under the hood, had to get a top post clamp because the car terminal ring plus the power wire ring were too thick and kept stripping out.

This was a few weeks ago with 18.5 cubes @ 17Hz. We just happened to get where we actually wanted to be with our "temporary" sloppy box. 22 cubes 15Hz.

My enclosure is 21 cubic feet after sub/port displacement, tuned to 15.42Hz. The port is a 7.75" sonotube 19.5" long, leaving 8.25" port clearance at the back.

external 42" wide = 40.5" wide internally
front 38 tall, rear 32 tall = 36.5" + 30.5"= 33.5" average height
bottom depth 30.5" top 28" = 29 + 26.5 = 27.75" average depth

40.5 x 33.5 x 27.75 = 21.788 cubs before sub/port displacement

7.75" x 19.5" = .532 cubes port displacement + .22 sub displacement = .752 total disp



WinISD with 21 cubes with 7.75 x 19.5 says 15.42Hz tune, and I round under, so close to 15Hz.




So here is my problem. Bass I Love You has a 16Hz tone. I had more excursion at the 16Hz tone than I did on the 30Hz and 25Hz tones. Please excuse the very poor quality of this video, turn your speakers down!

also note, very little port velocity. that 2 liter bottle barrely moves, and not much air blew through without the bottle in it either.

Now here is sub_junkie's vid. He is 7.6 cubic feet tuned to 15Hz as well. IDK where his SSF is set to, but mine was at 15Hz. You can turn it back up for his vid.

his excursion is just the opposite: more excursion on the 25Hz and 30Hz, very little on the 16Hz, as it should be, correct?


Here is another video of mine with a much better camera just to get a better view and listen of things. Please bear with me, it's a rap song, but the bottom note on this track is 26Hz I believe. Willie The Kid : Love For Money

PLEASE HELP! THANK YOU!
