n8ball2013 Posted April 8, 2011 Report Share Posted April 8, 2011 if you are tuned at 33 you will move the least at 33. as you go lower than tuning you'll move more and more the farther you go from that point. thats why it moves like hell at 30.

SPLadd1ct Posted April 8, 2011 Author Report Share Posted April 8, 2011 if you are tuned at 33 you will move the least at 33. as you go lower than tuning you'll move more and more the farther you go from that point. thats why it moves like hell at 30. I was actually thinking a little bit about that today. I thought to myself, well at my tuning frequency, my driver is perfectly "loaded". If I go above or below tuning frequency there will be an inequality in the back wave vs the front wave, allowing the cone to move freely since there are unequal pressures. For example I placed a paper towel in the port and slowly decreased the frequency in 1 hertz increments at low volume. I noticed that the paper towel had a tendency to slowly move toward out of the port the further I went away from my tuning frequency because I guess the back wave has more pressure? I am no expert at this stuff by ANY means, if you want an expert explanation on something, talk to me about firearms. I am somewhat decent at physics and understand some thing stuff fairly well. If some of my rationale is wrong please correct me, I accept constructive criticism with open arms. 2011 Ford Ranger Sport 4.0 v6 2 sundown audio prototype nsv4 15s crossfire 4k wired to 0.4 ohm 15 banks of maxwell 3.0 caps @ 18v triple alts (x2 us alt 250's, x1 singer 320) 153 at 23hz Link to comment Share on other sites More sharing options...
SPLadd1ct Posted April 10, 2011 Author Report Share Posted April 10, 2011 A little sneak peak of what I did today.... I mounted the amplifier to my backseat. Matt and I cut out most of the runs of wires too. I will hopefully be done sometime this week, or next weekend at the latest! 2011 Ford Ranger Sport 4.0 v6 2 sundown audio prototype nsv4 15s crossfire 4k wired to 0.4 ohm 15 banks of maxwell 3.0 caps @ 18v triple alts (x2 us alt 250's, x1 singer 320) 153 at 23hz Link to comment Share on other sites More sharing options...

LiftedZR2 Posted April 10, 2011 Report Share Posted April 10, 2011 The further you get from your tuning frequency you subs will unload, basically acting like they don't have a box. That's when $hit goes all wrong. The dust cap slaps the pole piece or the coil comes completely out of the gap and smacks the top of the pole. 1998 GMC ZR2 5" BDS suspension lift, 2" bodylift with 33" tires 1- Alpine iDA-X305SBT headunit w/imprint 2- DD 9500 18's dual 4's 2- DD S2b 2700 watts Each of old school class A/B power 1- DD S4b 4 channel for mids and highs 1- CDT HD 20th anniversary componet with upstage kit 2- CDT ES 6 3/4" mids for midbass in doors.
