Subwoofer impedance rise

[cubdenno 0]

I understand that a given sub in a given enclosure does not remain a "*" ohm speaker. The actual impedance is dependant on the frequencies being played. After watching the resistance dance around on my multimeter, I was wondering if there is a method to stabilize the impedance closer to what the woofer actually is and salvage some of that lost power from my amp.

well wire lower and hope ur impedeance rises above your smoke point....

a sub moves the ohms change.

i have seen people that have a math to the madness.. but i think its only for burps...

like @60 hrz the ohm rise is at 1 ohm..... so they wire the subs down to 1/3 of an ohm so that while thay are burping the amp sees a 1 ohm load.

from what i understand... but i have been wrong before,.

meh imp rise is very complicated. it changes depending on the sub, box size, tuening, and hz the sub is playing. if i rememeber larger boxes have a higher imp spike then smaller boxes. honesty i wouldn't worry about since theres nothing you can do to change it.

also remember if you are wiring to drop your ohm level that it not only rises, but it falls as well.
