Your fine.
what? elaborate on this please. as this makes no sense. neither one is ac or dc until the current and voltage is supplied which in the case of sound reproduction is ac. when you set your dmm do you set it to ac or dc resistance? theres not such thing.
in response to OP
most coils read a little low or a little high no big deal really it can be caused by temperature barometric pressures and millions of other things. your impedance rise will be in most cases 3 times your nominal load.
show me a dmm that lets you select ac/dc load? the only thing that would make any difference is the skin effect and that only matters when your actually inducing current. and that really only matters at high freq
well i can select ac/dc for measuring voltage but not resistance which is what your ohm load would be measured at. your resistance is always measured in ohms not voltage so therefore bill is correct....when you introdu e ac voltage from the amp the speaker moves but the voltage reading and the resistance only affect each other in the fact that the ac voltage causes the speaker to move which will cause the impedence to change.
now even with impedance rise, wouldnt the amp still see that .7ohm load internally? i mean ive heard you can also use longer speaker wire..etc.. to get a little ohm rise, but id still think the amp would still work as hard..
well **** i dont know lol.. i just figured that the amp itself would still see that ohm load, but on the way to the sub or whatever it would rise ofcourse.. im dumb, excuse me.. my A.D.D. is kicking in :help:
