I would have replied earlier, but I was measuring the output of my amp with a yardstick . . . What you hear is not the air pressure variation in itself but what has drawn your attention in the two streams of superimposed air pressure variations at your eardrums An acoustic event has dimensions of Time, Tone, Loudness and Space Everyone learns to render the 3-dimensional localization of sound based on the individual shape of their ears, thus no formula can achieve a definite effect for every listener.

Krakin Posted July 11, 2016 Report Share Posted July 11, 2016 Volts x amps only works in DC circuits. You need to have the power angle to find power in AC circuits, but that can be saved for another thread. To find port area in the easiest way I'll suggest you that link I posted.

Krakin Posted July 11, 2016 Report Share Posted July 11, 2016 Oh, I have no idea I don't know those clamps I just know most people use a cheap clamp that only accounts for amps alone.

Alright because it gave me 121.4V 28.7A is 3483w power factor of 4 leaving 3265w at the time of unloading 2000 Cavalier 4 doorXS D925XS D2400XS D31004 runs of 1/0 Mechman 270 2 DD 9515js Link to comment Share on other sites More sharing options...
audiofanaticz Posted July 11, 2016 Report Share Posted July 11, 2016 I forget what dd runs, but I think its something like 8 medium spiders stacked, that never really get too lose and sloppy. The PSI spiders from what I have noticed tend to get very lose, and could be part of your unloading issue.. If it was me I would shrink box size and leave port size alone. Pull out the woofers, build yourself a .25-.5 cubic foot box that you can screw inside of your box to shrink volume and test it on the meter.From my past experience with 9512s, they liked smaller enclosures at least if you are more number oriented.

Triticum Agricolam Posted July 11, 2016 Report Share Posted July 11, 2016 Before you go about getting a new box designed, it might be best to determine exactly whats going wrong with your current setup. audiofanaticz suggestion sounds like a good starting point. I would also suggest physically verifying what your tuning frequency is. You can do it by playing sine wave tones at moderate volume while watching how much cone excursion you are getting. The tone where cone excursion is the least is your tuning frequency. When you say you are having unloading issues, at what exact frequencies is this happening?
