There is no single standard. Many computer speakers are rated at 8 ohms while others are 16 ohms or higher. My computer subwoofer here is 4 ohms.
The speaker you connect to those terminals needs to be 4 ohms or greater.
For an 8 ohm speaker, 8 ohms is perfect. "Good" and "bad" are relative to the application.
A resistance reading of 200 ohms across the terminals of a woofer speaker is unusually high, as most woofers typically have a nominal impedance of 4 to 8 ohms. This high resistance could indicate a few issues, such as a malfunctioning voice coil, a broken connection, or an open circuit within the speaker. It's also possible that the measurement was taken incorrectly or that the speaker is not functioning properly, leading to inaccurate readings. In general, such a high resistance suggests that the speaker may not perform as intended.
Yes, but you will only be able to produce 120 W of power before you overdrive the speaker.
863,000 ohms.
If wired in parallel then 4 ohms.
The wattage and ohms of a speaker are not related; the resistance for speakers is usually 4 or 8 ohms.
The speaker you connect to those terminals needs to be 4 ohms or greater.
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.
Nothing is better.
Ohms is a measure of resistance. When the electricity passes into the speaker, some of it is 'resisted.' The ohms rating of the speaker is how much is resisted, and an indication of how much energy it takes to drive it - the higher the ohms rating, the more difficult it is to drive.
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.
For a 500-watt, 2-channel amplifier, the speaker impedance you need depends on the amplifier's design and configuration. Common speaker impedances are 4 ohms and 8 ohms. If your amplifier is rated for 4 ohms, you can use 4-ohm speakers for maximum output. However, if it’s designed for 8 ohms, using 4-ohm speakers may lead to potential damage, as it could push the amplifier beyond its limits. Always check your amplifier's specifications to ensure compatibility.
Study ohms law to get your head around it.
For an 8 ohm speaker, 8 ohms is perfect. "Good" and "bad" are relative to the application.
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".
Either 4 or 8 Ohms. It will be on the back of the speaker.
