Speaker impedance 4 ohms or 8 ohms - what's the difference?

Hello

I have a question, for some it may be funny, but not everyone has the same experience as you.
Looking through the speaker offers, I see impedances of 4 ohms or 8 ohms. How is it different?
I noticed that the amplifier for the 4 ohm speaker is cheaper;]
Why?

Thanks in advance for your answer

if these are similar models, the price difference is due to the fact that the 4ohm one has a lower accuracy than this one
to 8 ohms assuming that the eight ohm 8 ohms has the same power at 8 ohms as the 4 ohms into 4 ohms but that's just a guess even the fairies don't know that.

maybe other components czort knows it

I don't know, you graduated from middle school or 8-year primary school, if so, how to be careful about physics
so you would know what is 8ohm 4ohm 2ohm ix ohm (where x is a non-negative number)

ohm is the unit of resistance and is called ?
read about Ohm's law

the basic principle in acoustics, if there is a 4ohm amplifier, you can connect a 4ohm, 8ohm loudspeaker to it, and larger resistances, while connecting a 2ohm speaker (less than 4ohm) will overload the taste
similarly with the amplification of 8 ohms, except that connecting the 2ohm and 4ohm speakers (less than 8ohm) will overload it


the calculation of the equivalent resistance (calculation of the resultant impedance of several columns) can be found in reading about the ohma law
usually it is described there somewhere

Impedance varies :D

The amplifier will probably not be cheaper, but it will be able to deliver more power to the 4 ohm speaker than to the 8 loudspeaker. The question is, what amplifier do you have (you will have) and how many speakers you want to connect to it.

Impedance - resistance created by the loudspeaker system to alternating current. Most often we will have to deal with speakers with an impedance of 4 ? or 8 ?, much less often we will encounter 2 ? loudspeakers. Wiadmo, the lower the impedance of the loudspeaker, the lower the load on the power amplifier, so we are able to squeeze more of it (more power). For example, an amplifier that offers us 320W with a load of 8?, if a 4? speaker is connected to it, will play 530W. The same amplifier, loaded with an impedance of 2?, will be able to pull up to 900W. But beware, the smaller the load, the more current will flow through the power stages of the amplifier, and therefore the greater the probability of its damage.
Therefore, not every amplifier will be able to work without side effects at a load as low as 2?. So before you connect your package to the amplifier, make sure what the impedance is and what minimum imedance you can connect to the tip. Also, when replacing a loudspeaker in your package, in addition to power (and efficiency, because it is also worth remembering), you need to check the impedance of the converter and replace it with the same one!

I think about a pair of speakers

LDM P315 with a power of 300W / 4ohm

or

LDM C-151
Power (RMS / music): 250/500 [W]
Speakers used: 1x15 "+ Ceramic Active Switch
Impedance: 8 Ohm

... and I do not have power ends I have chosen .. I am asking for advice and whether these speakers are a good solution for parties like 18, etc., club music. I heard that what matters is the bandwidth and the size of the loudspeaker .. Is it true?

So the ones mentioned above are for the band, yes ??

The wallet resource is PLN 1,500 as of today;]

As for the band, these are budget money with a bad top.

Piezo-electric speakers do not sin with linearity.

I think that in your case it will be best to buy 4 ohms loudspeakers, you will use the amplifier more - you will get more power from it (and almost all stage players can work with 4 ohms).

the PLN 1,500 is supposed to be for a boost and loudspeakers? Will be hard. PLN 1500 is a used ads lx1100, or a new lx500
