Mell How do I choose speaker impedance?
You need to make sure the speaker impedance of any speaker (or speakers) connected to an amp is within the capabilities of the amp. Most HiFi amps are designed for a speaker load impedance of 4-16 ohms. This means the minimum speaker impedance is 4Ω.
Which impedance is best for speakers?
The lower the impedance, the more efficiently it allows the electric signal, which is basically the music, to pass through the speaker. Most speakers are rated at 4, 6 or 8 ohms, and cheaper receivers can sometime have issues driving low-impedance (namely 4 ohm) speakers.
Do you have to match the speaker impedance to the amplifier?
There must always be a match between the impedance of the amplifier and the impedance of the speakers. The higher the ohms, the lower the output power of the speakers. If the impedance of the speakers you put in the example is from 4Ω, 6Ω and 8Ω and the amplifier only send from 6Ω, that (6Ω) should be the correct impedance.
How to choose the right speakers for your amplifier or AV?
Our AV expert Tim LeFevre explains. Impedance: Measured in ohms (Ω), typically 4, 6 or 8. The lower the impedance, the more demand the speakers place on the amplifier, which is why matching the impedance of your speakers to your amplifier is important. Most home theatre speakers will be 6 or 8Ω, as are most home theatre amplifiers.
Can a speaker be connected to an amp too high?
So be careful when connecting speakers in parallel. The impedance can quickly become too low for the amp! Make sure the total speaker impedance isn’t lower than the amp’s output impedance. It can be higher, but then you might struggle with getting the volume you want.
How is speaker impedance related to dynamic range?
Speaker impedance is a measure of a speaker’s resistance to an alternating current. The lower the impedance, the more current the speakers will draw from the amplifier. If impedance is too high for your amplifier, the volume and dynamic range will suffer. Too low, and the amp could destroy itself trying…
