How do I figure out how many ohms if I bought my cab used from a store? it's a peavey 4x10 with a tweeter.. any info would be greatly appreciated. =)

cab question...

Next time the appliance tech comes over to fix your fridge,ask him to check it with his ohmmeter.it wont read exactly,they are nominal impedences.
good idea.. but the fridge never breaks.. is there a way I can get my own one? lol I wanna know b/c I'm buying a hartke 350watt head and if my cab it gets the 350 watts.. if it's 8 ohms it gets 240 watts.. so ya know =P
Well,you could haul the cab down to a repair shop,any repair shop should have an ohmmeter,but thats a pain.I saw ohmmeters on the half-off table at a hardware store recently(about 25.00)radio shack has 'em,or any appliance parts house.just dont get one of those cheap continuity checkers,it will read 0 ohms even if the impedence is 16 ohms.
If you take the cab somewhere,take your speaker cable too,plug one end into the cab,check resistance at the other-thats probably obvious.

Well, I was heading over to radio shack later this week anyway =) going to pick up a nice lil ohmmeter and a plug things that I acn plug into my stereo as the headphones and will connect into my computer as the mic =) I'm going to record a few of my songs onto the computer for further mastering with Cool Edit Pro then make them mp3s so it's nice n' quick to send to my friends.. hehe *brains starts to works very fast*
anyway.. thanks for the help man =)

For an 8 ohm speaker, you will probably read 4-6 Ohms. For a 4 ohm speaker, you will probably read about 2-3 ohms. A 16 ohm speaker will have about 10-12 ohms resistance. If there is a crossover in the circuit, there is no telling what you may read.
Reasoning? The multimeter will measure DC reisistance only. The numbers we talk about in the speaker world are impedance, which is like the AC equivalent of resistance. The speaker coil is an inductor, so it impedes the flow of AC current. So it has an impedance a little higher than its resistance.

A simple way to tell would be to post a query on the forum on Peavey's Web site, with the serial # and all that. Their tech's trawl the forum and will likely respond.
ok, well I bought myself a multimeter.. um when I go to measure the ohms the # keeps rapidly changing.. how do I know how many ohms my cab is?? =(
Sounds like you have a digital meter,try to make as solid contact as possible with the leads.use alligator clips if you have them.The lowest number is probably the closest to correct.Also,make sure the meter is set to the lowest scale.
I finally got it to work.. =) it's reading 4 ohms but I went to the peavey amp forum and gave em the serial #.. and they said it was 4ohms.. is it actually for or could it be 8?? hehe I'm mixed up now =P

Take a look at the new bassplayer and the article is also on the internet. it explains the ohmeter-thingy-na-bobber and how it works and stuff.
