OrionStang Posted August 18, 2012 Report Share Posted August 18, 2012 My deck and gains are set with DD-1 at volume 33 of my headunit, yada, yada. Its done right. I was playing around with some tones today, and with the volume at 30 all was fine. But at volume 31, the sub kind of sucked in (instead of the normal pushing out). Don't know how else to explain it LOL. Of course output was less and it sounded shitty, but no bottoming out. I did not do it over and over to figure out, not worth risking damage to the sub. What is happening? Quote SMD Super Seller My Feedback Thread Link to comment Share on other sites More sharing options...
skittlesRgood Posted August 18, 2012 Report Share Posted August 18, 2012 i had a mid do that before. i believe that happens because of the back wave. try putting some cones or egg cartons on the wall behind the sub and see if it goes away. at least to test it.

OrionStang Posted August 18, 2012 Author Report Share Posted August 18, 2012 Inside the box? Note: It only did it on test tones, its fine on music. CD is the official DB Drag disc. Quote SMD Super Seller My Feedback Thread Link to comment Share on other sites More sharing options...
MrSkippyJ Posted August 18, 2012 Report Share Posted August 18, 2012 probably just an optical illusion since you were just playing a tone. With music, your sub is playing lots of other frequencies (harmonics, other instruments, etc...) so it would look different than a tone. where as a tone is a single frequency with little else going on.

OrionStang Posted August 18, 2012 Author Report Share Posted August 18, 2012 Definitely not an illusion. I was looking right at it. Volume 30=nice excursion and clean sound, volume 31=sucked in, lost output, shitty sound. Quote SMD Super Seller My Feedback Thread Link to comment Share on other sites More sharing options...
Team Bassick - Kimo Posted August 18, 2012 Report Share Posted August 18, 2012 even more so. the back wave can be a bitch when using tones. could cause you to lose up to 3 db's. Now the question is did this happen on all frequencies or just a certain range like 40-45?

OrionStang Posted August 18, 2012 Author Report Share Posted August 18, 2012 Sub fires forward, box pushed all the way back in teh trunk. Happened on 32, 33, 34hz, then I stopped because I don't want to hurt it. Box tuning is 35, if thats relevant.

Team Bassick - Kimo Posted August 18, 2012 Report Share Posted August 18, 2012 all is relevant. however, trouble shoot everything to do with wiring first. may have one voice coil out of phase. I know a pair of my dc's one voice coil was out of phase always even though on the connection was red and black it was always losing volume. it was bitch to say the least every rebuild.

stevog Posted August 18, 2012 Report Share Posted August 18, 2012 What track did you use on the dd1 sometimes tones are 0db. Quote Link to comment Share on other sites More sharing options...

I'm about to pull everything out to build a new box anyway, so ill be sure to check the voice coils. Outside connections are all good. Its just one of those "start from scratch" things I guess.
