SnowDrifter Posted October 28, 2011 Report Posted October 28, 2011 (edited) Why would a subwoofer suck in under heavy bass lines? I have tries it with 3 different subs, 2 different amps, a mixer, and an iPod + phone with RCA plugs and all have the same effect of sucking in on loud bass lines. Could it be an issue with the ported box? It also happens regardless of song or sine wave Edited October 28, 2011 by SnowDrifter Quote ~~~~~~~~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

SnowDrifter Posted October 28, 2011 Author Report Posted October 28, 2011 I should also add that it still plays bass like it should - just like it's only on the back half of the x-max Quote ~~~~~~~~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
n8ball2013 Posted October 28, 2011 Report Posted October 28, 2011 you didnt check it. Its out of phase thats why it pulls in when it should be pushing out. somewhere you have it out of phase.

I don't mean pulls in when it should be pushing out. I mean that it plays in phase, but it's like the entire sine wave has shifted so that the 'zero' point is no longer true 'zero,' but like it's in the negative Quote ~~~~~~~~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
Guest Posted October 28, 2011 Report Posted October 28, 2011 its out of phase. listen to the man. how did you even "check" if its out of phase? Quote
SnowDrifter Posted October 28, 2011 Author Report Posted October 28, 2011 (edited) its out of phase. listen to the man. how did you even "check" if its out of phase? Checked the input (3.5mm to XLR), then checked the crossover(XLR to XLR), then checked the wires going from the amp to the sub(Red to Red to Red). I am using a mixer, DJ crossover, and a DJ amp but using car subwoofers. And it plays completely normal at low volumes, It's only at high volumes that it shifts the peak from being say +5mm - -5mm to +3mm - -7mm Edited October 28, 2011 by SnowDrifter Quote ~~~~~~~~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
412 CVX Posted October 28, 2011 Report Posted October 28, 2011 reverse the phase just for shits and giggles. see what happens. Quote Just say no to Ground Pounder Customs. My temp system build log More box buildssome cars do over 170db with one sub, so clearly my two 12"s can do that in my car, with my knowledge too! look out bitches! I'm with captain stupid.
SnowDrifter Posted October 28, 2011 Author Report Posted October 28, 2011 (edited) reverse the phase just for shits and giggles. see what happens. Same thing. But it seemed to go away regardless of phase when I turned my mids and high off? Let me go play around with this a little bit. I will be back Edited October 28, 2011 by SnowDrifter Quote ~~~~~~~~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
