How do you measure speaker impedance?
The real impedance is the resistance in ohms more 20%. A coil resistance of 6,7 ohms X 1.20 = an impedance of 8.04 ohms. If the voice-coil had exactly 8 ohms, the impedance would be 9.6 ohms and the sound would be unclear, tending to more basses.
Definition of low impedance medium impedance and high impedance?
For instance: A microphone rated at 150 ohms to 300 ohms is considered low impedance. About 600 to 2 000 ohms is medium impedance, and 10 000 ohms or more is high impedance.
What does the 8 ohm speaker mean?
A speaker is a device that converts varying electrical signals into varying acoustic signals so that you can hear them as sounds.An 8 ohm speaker is a speaker that has a nominal impedance of 8 ohms. This means that is presents a load of 8 ohms to the amplifier over the range of frequencies that it is designed for. You should match the impedance of the speaker to the designed impedance of the amplifier. Failure to do so will result in inability to achieve rated power output, and it could lead to amplifier and/or speaker failure.There are other factors involved as well, such as power capacity, shape, resonant frequency, and expected enclosure design. Speaker designers spend a lot of time and money on selecting a particular speaker, and you should not arbitrarily substitute one for another without adequate justification.
Is 5000 ohm is high impedance?
Relative to 500 ohms 5000 ohms is a high impedance. It is ten times higher.
What is the resistance of four 8 ohm speakers wired in a series?
Two 8 ohm speakers in parallel is 4 ohms, and the power will be split between them. However, unless the amplifier is rated for 4 ohm operation, you will not get the same total power out of the amplifer as you would with an 8 ohm load.
What is rear 8 inch speaker impedance?
The nominal 8 inch speaker impedance can be 4 ohms, 8 ohms or 16 ohms. It depends on the make of the loudspeaker not on the 8 inches.
Will 8 ohm speakers work with 816 ohms of impedance?
yes but will barely hear anything. If you have 816 Ohms of impedance then your speaker is probably bad.
If you have 8 ohm monitors rated at 95 watts rms and a 150 watt per side amp at 4 ohms Will this amp work for these speakers?
Strictly speaking, there are no 4 ohm amplifiers. An amplifier will have an output impedance of around 0.02 ohms. In hi-fi we have always impedance bridging. Zout << Zin. That means that the output impedance of the amplifier is much less than the impedance of the loud speaker. The damping factor Df = Zin / Zout tells you what Zout is. If the damping factor Df = 200 and the loudspeaker impedance is Zin = 4 ohms, the output impedance of the amplifier is Zout = 4 / 200 = 0.02 ohms. Scroll down to related links and look at "Voltage Bridging - Zout < Zin". Most amplifier manufacturers offer guidance on the minimum impedance speaker that can be used with the amplifier. Generally, an amplifier that is quoted at 150W at 4 ohms will be designed to run with a minimum impedance of 4 ohms on the output. An 8 ohm speaker will work without any problem at all but the output power will be rather lower than the 150W quoted for a 4 ohm load. The power rating of the speaker is an indication of the amount of power that the speaker can handle without distorting. If the speakers are being used as monitors with a fairly close listening position, it is unlikely that they will be driven close to their power limit.
Can you match a 6 ohms impedance amplifiers with 4 ohms speakers?
There is really no 3 ohms amplifier on the market with an output impedance of three ohms for power matching. You will find there 0.3 ohm or less for voltage bridging. Scroll down to related links and look at "Interconnection of two audio units - Power amplifier and passive loudspeaker".

My surround speaker are 8 ohms front speaker are 6 ohms the amp is set to 6 ohms What is the impact on surround speaker?
The speaker will be fine and there will be little impact on its performance. In these situations, if there is a problem, it will be with the amp because that is what delivers the electrical current to the speaker. The situation you want to avoid is having speakers with a lower impedance connected to your amplifier. So you might have had a problem if your surround speakers were 4 ohms. However, as they have a higher impedance than the amp is set for, I wouldn't worry about it.
How many speakers can go into a single stereo system?
All amplifiers are rated to handle a certain speaker impedance. The majority of loudspeakers have an impedance of 8 ohms while most amplifiers will be able to drive a minimum load of 4 ohms. It is important to check the ratings of the amplifier before adding more speakers. If two 8 ohm speakers are wired in parallel, the total impedance will be 4 ohms. If 3 speakers are wired in parallel then the total impedance will reduce to around 2.5 ohms. If the total speaker impedance is lower than the rated impedance of the amplifier, it is quite possible to damage the amplifier as the output level is increased. To be safe, make sure you understand the impedances of the speakers and the amplifier's rating before hooking anything up.

How can you tell if a 4 channel 800 watt car amplifier is 2ohms or 4 ohms?
Your 4 channel amplifier has neither a 4 ohms nor a 8 ohms output impedance. The output impedance will be smaller than 0.5 ohms. In audio we only use amplifier and loudpeaker bridging. Don't believe the myth of matching. Scroll down to related links and look at "Impedance bridging - Wikipedia".

Definition of low impedancemedium impedance and high impedance?
There is no precise definition, but for instance: A microphone rated at 150 ohms to 300 ohms is considered low impedance. About 600 to 2 000 ohms is medium impedance, and 10 000 ohms or more is high impedance.
How do you measure speaker ohms?
Usually speakers are rated by DC impedance, so you can use a simple multimeter to measure their resistance. Typical values are 4 to 32 ohms.
