We shopped for a Buick Rendezvous or Pontiac Aztac so we could get >18 cubes and still have room for kids, grocieries and such and avoid getting a minivan. Explorers, Blasers, Bravadas, and the like we'ren't nearly enough.

Basically we are walling the hatchback. >20 cubes, 8" port. This is temporary until a 21" or 22" driver of similar specs is finished. ( >30mm Xmax, <20Hz Fs)

I originally designed it to have the sub on top and port on bottom, but once the 22" is in, side by side works better.

free air 16Hz or 20Hz

http://www.youtube.com/watch?v=jKYkNrd9KQ0&feature=channel_page

bass i love you free air aprox 4.5 - 18 watts according to DMM... demo just to show 7Hz signal is lowest, not 18Hz in that track

http://www.youtube.com/watch?v=Equ_XPb75dE&feature=channel_page

DMM showing 5.7 volts during 7Hz tone, 6x6=36 watts/2 ohm= 18 watts

http://www.youtube.com/watch?v=DiHlU5EwQXI&feature=channel_page

no more than 12 watts DMM

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.

[IMG]http://i248.photobucket.com/albums/gg178/kryptonitewhite/mix5/ib31815hz21cubes.jpg[/IMG]



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!

http://www.youtube.com/user/kryptonitewhite#p/u/31/zD9FU-SZLOY

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.

http://s536.photobucket.com/albums/ff323/airsoftsniperm4/?action=view&current=UTGM324Gen3forSale005-1.flv

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

http://www.youtube.com/user/kryptonitewhite#p/u/18/3jzenFwzkZk

same song, different vid

http://www.youtube.com/user/kryptonitewhite#p/u/17/yGWsO36WPtc

PLEASE HELP! THANK YOU!

you need to see when your imp gain is at its highest. at the resonant freq it should barely move and the impedance rises to its peak. maybe the tuning is incorrect, or cabin gain may play a part.
