What does speaker A minimum 4 ohms speaker impedance means?
The speaker you connect to those terminals needs to be 4 ohms or greater.
Is 8 ohms good or bad resistance?
For an 8 ohm speaker, 8 ohms is perfect. "Good" and "bad" are relative to the application.
Can you use 120 W speaker 8 ohms for 200 W amplifier?
Yes, but you will only be able to produce 120 W of power before you overdrive the speaker.
How many ohms is 863 k ohm?
863,000 ohms.
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.
