Just wondering what gives a speaker it's impedance ohmage. Eg. Same speaker size etc, but comes in a choice of either 4 or 8 ohms. Is it the number of coils in the drive etc ??
The number of turns of wire in the voice coil, to put it simply. The correct term is impedance, which is measured in ohms. There's no such thing as ohmage.
Captain G, you've been Ohm'd. Sorry, I just had to say it... I wonder where the word "ohmage" came from... it comes up a lot on here.
Say I have a 4ohm and an 8ohm cab in parallel. Does the 4 get twice the watts or is it spread out equally to each cab? Something inside me says the 4ohm gets twice the wattage (watts?) but I can't remember why.
Like I said, to put it simply. Just about every detail of the driver has some effect on the impedance, even the frame material. The composition of the gasket, maybe not.
Correct................... The two speakers together will present a 2.67 ohm load to the head. The 4 ohm speaker will recieve 2/3 the power, the 8 ohm will get the other 1/3
Yes apparently he was last seen putting resistors on the stove and singing "Ohm, ohm on the range...."
No, I remember guys using the term in the seventies! Speaking of misnomers, my old keyboard player used to call a C# diminished chord a C7 with a raised root!!
However it happened, 'ohmage' is now listed in at least two dictionaries, Merriam Webster and the American Heritage. So it is "a word" ... not that it's a good one, mind you, or the correct term for discussing impedance (I think both of the above-referenced dictionary entries define 'ohmage' as relating to resistance). Cheers
http://dictionary.reference.com/browse/ohmage This is worse than when they added "crunk" to the Merriam-Webster Dictionary... :scowl:
But not in the AES listing of approved engineering terms. That's because ohms are used to measure impedance, resistance, inductive reactance and capacitive reactance. Specifying 'ohmage' one does not know which of the four possibilities is in question. Suffice it to say no engineers are on staff at dictionary publishers.
Thanks for the reply BP! Now I remember, the amp *sees* the 4ohms as 2x8ohms, simplifying it to 8x8x8 and each 8 gets 1/3 the power.
Come on, now, what's wrong with ohmage? There's voltage wattage, amperage, as well as doob-age, flame-age (a la Pauly Shore), etc... ...on second thought... lol
