Understanding Impedance: Comparing 4 Ohm vs. 8 Ohm Speakers in Audio Quality

I have a question. What is the difference between an 8 ohm speaker and a 4 ohm speaker??? Is there any difference in listening??

4 and 8 are the matching of the speaker impedance to the amplifier output.
Output 4 you give speaker 8 and you lose power
Output 8 you give speaker 4 and lose the speaker
greetings.monika

ad 2 you lose the amplifier

The best speakers are 6 ohms

Why are 6ohms the best??? Your real name is Monika, that would indicate => a girl interested in acoustics!!! Interesting

these 4 ohms are usually "louder" at the same volume potentiometer setting. Why count the power from the formula: P=u^2/R Of course, if the amplifier allows it

, the best speakers are 6 Ohms, because it will melt. If this was supposed to be a joke, it worked

this burning thing is nonsense... I'm talking about burning the amplifier or loudspeaker - I tried a 4 ohm speaker with at least 5 amplifiers and nothing happened, and I also use it as a test speaker for car audio.
Well, maybe everything is getting a little hotter...

Most new amplifiers work at 4 and 8 Ohm, but old amplifiers (especially Polish ones) were very sensitive to it. Most were only 8Ohm and after connecting a 4Ohm speaker the terminals simply fell off. although not always....

As Deamon writes you lose the amplifier, not the speaker

so for an 8 ohm speaker I also need an 8 ohm amplifier? and to 4 ohms... 4 ohms? and is it seriously true that 4 ohms sound better??????

If you have speakers with identical parameters, differing only in resistance, they will sound the same.
Ps.4 Ohm can play louder, but only because of the amplifier.

similarly, a 1 ohm loudspeaker would play even louder. Some manufacturers even provide parameters of amplifiers with a load of one ohm, resistance is just crap that causes losses in the current flow, which causes the elements to heat up, etc. Impedance, however, ehm... is a different topic
As for our domestic amplifiers, maybe this was actually the case - I remembered the WS354, which burned down, probably because of the 4 ohm speaker, but I'm not entirely sure... it's old news.

Sure, Falco, these 6 ohms are a joke
They ask difficult questions on the forum and I don't know what to write
The truth is, however, that most multi-channel receivers cannot cope with 4 ohm speakers and even if they do not burn, the power will be pathetic.

something strange, Polish 8 ohm amplifiers burn from 4 ohms hmmmmm :?
and I tortured an 8-ohm amateur 3 stereo with almost 2 ohms for 1 hour (of course with a wired fuse 8) and nothing happened
Yes, there was a microwave inside and it got so hot, but it didn't burn
I connected the 8 ohm ws303 to the 4 ohm lw1200 and it worked too
everything was getting very hot, but after 1.5 hours nothing burned
unitra aida also 8 ohm 4 ohm lw1200 also a microwave but even the fuse didn't work and here it wasn't wired
but it's a different matter with old 8 ohm crap (stk).
as soon as you connect 4 ohms, you're dead within half an hour :(

and as for which ones are the best......
I propose a 1 ohm speaker I got one from qmpl, the coil was damaged but I was unaware of it and connected it to an 8 ohm amplifier... 8) after 5 minutes, smoke started coming out from the amplifier which was playing at 1/4 power, 8O, I turned it off and measured the resistance, and here it was 1 ohm 8O
but it played loudly

micho, don't be picky because I wrote that it's not always...
Greetings

aha, so I conclude from what micho wrote that I can drive 4 ohm speakers with an 8 ohm amplifier? I understood?? :] of course I won't do this. I have 4 ohm speakers and I need to buy a 4 ohm amplifier for them??? tell me plz ;] Regards!!!

deamon, I'm not picking on you, spox I'm just telling you what's going on with Diors
karmel67 I'm just writing my practical experience, but up to 4 ohms it's better to use a 4 ohm amplifier, in general 4 ohms are better, because if you connect 8 ohms to 4 ohms, you will lose power, but it will heat up less and the chance of it burning out is very small, and if the speaker is 4 ohms it's normal
however, if you connect 4 ohms to 8 ohms, the woman told her fortunes in two 1 will last for 8 hours, it will get so hot that you can't touch the transformer or the radiator, but one will last for 20 minutes, 4 ohms and that's it so a 4 ohm amplifier will support 4 ohm loudspeakers

if you have 4 ohm speakers, if you buy such an amplifier you will be able to play calmly, but you can also risk playing with an 8 ohm amplifier, let's say you have a 50% chance that it won't burn out

the point is that if the amplifier is e.g. 2x20W only at 8 ohms, if you connect a 4 ohm speaker, the amplifier will have to put out about 30W and it may not be able to withstand it and the power amplifier will burn up, but sometimes it doesn't burn up so you can risk it.

Someone once wrote on the forum that the same model of a 4- and 8-ohm loudspeaker is not the same, it differs in some parameter and, for example, it must be taken into account when calculating the casing and under no circumstances should the 4-ohm to 8-ohm loudspeaker be replaced in the same column because it will no longer fit. .I didn't want to argue, but it seemed nonsense to me. I can't find this post because I would give a link.

ok, I'm slowly starting to rant about what the heck... I'm going to the stock exchange on Saturday, so I'm buying a 4 ohm amplifier. and what about 8 ohms and these voltage drops? It's still a long road ahead of me

Pi-Vo, you talked about these differences... When I was building a sub on LW800, I also noticed differences between 4 and 8 Ohm

Qts Qms Qes Vas
4 - 0.51 2.96 0.62 30
8 - 0.41 2.41 0.55 29

The fact that we shouldn't replace them under any circumstances probably meant the crossovers.

well, my lion has 800 (4).
Qts 0.4
Fs34
Vas 31
Qms2,486
qes 0.486
these are the measurement results... so what alphard says can be taken today.....

as for the Polish amplifiers, I have a Polkata chord 41 and my friend didn't know, he connected the speakers to the cap, then when I checked it turned out to be 2 ohms... and the 4 ohm amplifier didn't burn anything, but the transistors got a little warm... a little bit because it never happened there they don't play

i-Vo
Theoretically, loudspeakers made in a similar way have parameters independent of the rated impedance, but in practice either 4 ohms are used in the same slot and then the differences are tangible, and even when the slot is changed there will be minimal differences due to the production processes.
