are all 15 inch speakers rated at 8 ohms?
455076
No.  Any speaker can have any rating.  Generally speaking though, most speakers impedances lie in the range 4-16 Ohms.

Easy!\nIf the input is the same(1.1kW) it depends on their performance.

It's obviously not electrostatic, if its resistance is that low (electrostatic drivers show infinite resistance across the terminals).  The fact that you read 32 and 64 ohms is very suggestive.  I assume this is what you got:\n\no<---32 ohms--->o<---32 ohms--->o\n|<----------------64 ohms--------------->|\n\nIt looks like it was intended to be driven by the push-pull output of a transistor amplifier.  OK, for a single-ended amp, just try either the 64 ohm, or one of the 32 ohm conections.  Whichever is louder represents the best impedence match.

This is a little too complex a question for free answers.  But:\n\nLower NUMBERS in gauge correspond to larger AREA of the wire cross section.  The larger the area, the more amerage can be safely carried by the wire.  Voltage is not really an issue at common household voltages, as most modern wire is rated to 600V and household doesn't exceed 220V.\n\nIn-wall wiring is solid copper.  You will generally match the wire gauge to the circuit breaker size as follows:\n\n14 gauge = 15 amp breaker (15 amp max)\n12 gauge = 20 amp breaker\n10 gauge = 30 amp breaker\n\nThe use of watts is misleading; it's AMPS that matter.  But watts * volts = amps, so you can deduce amerage from reading the wattage value, and knowing the current in your home.  The in-wall wiring specs are not generally limited by wire LENGTH, at least not in the way extension cords are.\n\nExtension cords, unlike in-wall wire, are not solid copper.   However, they're also less likely to burn down your house.  They are rated by wire lngth and gauge.\n\nYou can use the links I've provided here to see required gauge sizes.  Most indoor space heaters are 1500 watts (about 12 amps) though  some are 1750 amps.

I don't think the ricers sound good at all.  Give me my AMERICAN rumble.  Drown the ricers.  Nothing sounds better then an American rumble (GT Mustang 3" pipes with a flowmaster 80's).  Don't know why anyone would want to sound like a dirt bike or a ticked off wasp.

try\nhttp://www.dir.ca.gov/title8/2395_42.html\nsection b\n\nGrounds are also tied to the cold water pipes and gas pipes.\nmake sure all circuits are dry and checked with a insulation resistor tester (megger).Readings above 2 Mega Ohms should be OK.

Nominal= 36ohms\nTolerance=5% \nMultiply nominal by .05 , then add that figure to nominal for Max,.subtract it from nominal for Min.,,and study your ohm's LAW!! ;-)=

Check this site.  It might help:\n\nhttp://www.laptopical.com/news/13451-laptop-speakers.html\n\nGood Luck

There could be a problem with the wiring since you say it corrected itself before.  It maybe time to get another set of speakers.

in one case you have half an ohm, in the other you have over 500 ohms.  It seems you may be reading one of the meters incorrectly.  One of the meters could be set to auto, while the other is not.

Ampeg SVT is by far the best base amp.Try to find a good used one.The 8,10 inch speaker cabinet is like a wall of sound.\n        You might as well spend a little more now to get what you want or you'll regret it later.I'm a drummer but I also play base,so I can relate.

Sound is usually measured in decibels

ohm, or om is correct. om is supposedly the sound vibration when the universe was created

No matter what is the voltage rating, isolation or insulation is tested by using "MEGGER".\nThe value should be atleast above 1 Mega ohm in any case
