Zak Massey Posted July 8, 2013 Author Report Share Posted July 8, 2013 I had just used a 9v battery. I googled 'subwoofer pop test' and the vid I found the guy used a 9v so that's what I did. Polarity was all correct but only a little movement.

SnowDrifter Posted July 8, 2013 Report Share Posted July 8, 2013 No, sorry they are in separate chambers 5 cubes per. The chamber is 21 deep x 18.5 wide x 19.5 tall the port is 21 deep x 18.5 wide x 2.5 tall. After displacement and all that jazz the chamber is 5.01 cubic feet and the port is tuned at 31.2 hz I just double checked the numbers. And what I'm getting seems to line up with your results/problem. The box is WAY too small I assumed what you were giving me was internal dimensions, so I had to add 1.5" to the external dims to compensate for the wood thickness ~~~~~~~~SAY NO TO PHOTOBUCKET~~~~~~~~ Snow's DD-1 tracks here: https://www.stevemeadedesigns.com/board/topic/167433-snows-dd-1-tracks/ My take on OFC vs CCA: https://www.stevemeadedesigns.com/board/topic/110381-things-that-piss-you-off-in-the-car-audio-world/?do=findComment&comment=2461444 Link to comment Share on other sites More sharing options...
purplesyrup Posted July 8, 2013 Report Share Posted July 8, 2013 I was thinking the port looked very small too Link to comment Share on other sites More sharing options...
Hellbilly429 Posted July 8, 2013 Report Share Posted July 8, 2013 Is the box flexing too? Kinda hard to tell with that shaky video but it almost looked like the front baffle was moving some Could be my eyes to, just curious 2018 Honda Civic Sport Hatchback (build in progress) NVX Sound Deadener (Front Doors) Stinger FAST Rings Stock Electrical SSA Evil 6.5's Front Speakers Stock rear speakers MB Quart ONX4.80 speaker amp Rockford Fosgate T-1500bdcp DC Level 4 12" D1 @ 2-ohm Box In Design Stage Stock RadioMy Build Log Link to comment Share on other sites More sharing options...
CleanSierra Posted July 8, 2013 Report Share Posted July 8, 2013 ^^^I mentioned the port area 3 days ago It doesn't sound like it has the output that 2 18" BLs on that kind of power should have. I can't believe that it would be ALL the recording devices fault. Those subs should get downright nasty. I never ran any numbers on his enclosure, but if he's in the 3 cube range, that is why they sound like a couple of 10s Im not the one you want to try to troll. Just a fyi for you.

CleanSierra Posted July 8, 2013 Report Share Posted July 8, 2013 It sounds to me like the box needs to be destroyed and starting over with a good design needs to happen. Something isn't right, that's for sure. Im not the one you want to try to troll. Just a fyi for you. Link to comment Share on other sites More sharing options...

Zak Massey Posted July 8, 2013 Author Report Share Posted July 8, 2013 I've double checked the math and you are correct... The box is 4.375 cubic feet. Now i'm going back to the shop that made that box and ripping them a new a**hole.
