The power of the speakers in relation to the power of the amplifier.

A question that keeps coming back like a boomerang.
I read a lot of guides, posts, talk to people who know the topic.
I did not receive a clear answer to the question:

HOW TO EFFECTIVELY CHOOSE THE SPEAKERS POWERFULLY TO THE AMPLIFIER?

What tutorial, what man is a different theory ...

Let everyone who has something to say on this topic contribute their five cents.

It seems to me that not only I am wondering about this issue and not only your posts will help me ...

I'm waiting for some discussion ...

And dear friend, you will not get it, because as you write what a man is a different theory.

https://www.elektroda.pl/rtvforum/topic794476.html

As for me, it makes no sense to buy stronger speakers from the amplifier because then you will not use their possibilities, and vice versa. I think that an amplifier with slightly more power than the speakers is the best solution. But this is just my opinion.

that's why you buy speakers for an amplifier Theoretically (this is what I heard) that the power of the amplifier should be half the power of the speakers, You have to do a little research on the Internet and you will find out everything

Not only yours
The topic was rolled over many times, however, so I believe that another discussion is unnecessary ...

It probably depends on where the equipment is to be played. If you only use it or someone who knows it, you should have a reserve of power in the amplifier - it controls the loudspeakers better.

If, on the other hand, the operating equipment is unfamiliar, he will definitely want to turn the volume up to max someday, then a smaller amplifier. Why ? Mostly the loudspeakers (loudspeakers) are more expensive than repairing a sound ...

No offense, but car audio is fun for thinking people, not for those who turn the gain to the limit ... And by the way, the twisted amplifier can damage even 3 times stronger speakers than the power of this amplifier (especially the tweeters).

it starts again

stronger than the speakers

The amplifier must be weaker than the loudspeaker power it seems to me that a logical person will find out that too powerful an amplifier can damage the speakers

I can't explain how much, too weak an amplifier can also destroy the speakers. In fact, the loudspeakers are mainly destroyed by human STUPIDGENCY! And if the amplifier is stronger than the loudspeaker, it controls it better. But answering the first question, it is not possible to clearly answer how to match the amplifier's power to the loudspeaker, because watt and watt are not equal to. And it often happens that a good 200 W amplifier will control the loudspeakers better than a weak 500 W. Especially when the amplifier is selected for the front system, where power is much less important than quality.

I repeat once again that the optimal solution is an amplifier with more power than the rated power of the speakers.
Gain is here to use it properly ...

You might as well advise someone who buys a car to buy one with a maximum speed of not more than 140 km / h because there are speed limits, the roads are dangerous, and if he buys a faster one, he will be tempted to throw it on the floor and it will crash.

Did you take into account the maximum speed of the car when buying it and did not make it too high? I suspect not ...
Amplifiers, just like cars, are for people who are smart. You have a gas pedal in the car and gain in the amplifier ...
Following your reasoning, we should all drive little ones, because if we buy a faster car, we will be tempted to throw the gas on the floor and we will drive 250 km / h on our Polish roads ...

I would like you to respond to this
namely, I open the list of uDimensiona products,
a company that cares about quality and customers,
The products are divided into classes.

Of the sixteen, I see El Comp 6 here
They have 60W RMS
Not seeing an equivalent in amplifiers
I can assume that they are recommended for the radio itself.
Somewhere else I read that this is a set that,
I install myself instead of standard speakers,
to improve the sound quality.
So uDimension for the radio, which has about 18W RMS, recommends the use of speakers with a nominal power of 60W.

A class above,
another set of 16,
Jr. Comp 6.
Set with a nominal power of 70W.
I find equivalents in the form of amplifiers of the same class.

Jr.4-300 - which has 50W RMS on the channel
and
Jr.5-390 - which has a 40W RMS channel

The 5-channel amplifier also has a channel
with a nominal value of 100W RMS
on sub,

The first subscriber I see in this class and not only is it
Jr. 1004 v2 with a power rating of 150W RMS

100W RMS Amplifier + 150W RMS Speaker

There is also a Jr series amplifier. two-channel,
namely Jr. 2- 370 with the power of 2x125 W RMS.

I presume that it is used to connect two Jr. 1004 v2. (150 WRMS)

In sum..

The manufacturer uDimension in its products envisaged the following configurations:

Amplifier + Speaker
18W + 60W
40W + 70W
50W + 70W
100W + 150W
125W + 150W

please respond to this ...
It seems to me that such a producer of such class
he knows what he's doing ... and it's not just about safety
None of these amplifiers
it is impossible to choose a speaker with a lower power,
is this an oversight ?? manufacturer's blunder ??

That's how you figured out the producer 100%. Only the manufacturer does not launch his product line, only cooperation with his other products. Anyway, soon your theory will crash because the Element 2x 60 W amplifier will come out. How did you think that Jr. 2- 370 is for driving 2 subs, I don't know either. It is an amplifier rather designed to drive the front, so a mistake again, because 2x125 vs 2x70 junior comp 6. Anyway, as I said, the power in the front set, although it has some importance, but the most important thing in this case is the quality of the amplifier.
And you also got lost in all the higher series of prox amplifiers.
Generally, your theory blew me away

I will only take a stance on this arrangement because I have Jr 6 in stock now.
As a matter of fact, the manufacturer gives the rated 70W RMS, I tested them with the Helix HX400 Espirit amplifier (rather higher league) 70W for 4 ? at rated parameters (without alternator operation) well it sounds good ... but I feel unsatisfied what am I doing? ..... I connect the Helix to the 2x bridge, i.e. sum sumarum, I put 250 W on junior women and what ... completely different music . Of course, the deal is for ... thinking people. It's just like on National Geographic ... gives food for thought.
Believe in some regularities that "it is better to drive a 100 horse seicento than a standard one, and it seems to have less fuel and much more dynamically".
so much from me.

You would connect to it Audio Arta 50hc or Orion 225hcca, Audison CS300 all around 2x25 W and you'd be surprised what they do with them

Unfortunately, these are all just your assumptions, you have not given any proof that the speakers with a power of 60W RMS should be powered by the radio itself ...

Of course, sometimes you can meet the manufacturer's recommendations regarding the power range of the amplifier, and sometimes a lower power is recommended. Such tips are given to complete laymen only so that they do not connect a much more powerful amplifier and unscrew it to the max.

After all, if the manufacturer recommended a more powerful amplifier in the manual and someone who does not know about it connected just one and burned the speakers by turning the gain to the stop, then he would later claim his rights under the warranty, because the manual said to connect a more powerful amplifier ...

The power recommendations given by the manufacturers are only for laymen. Have you ever encountered a situation where in a car audio workshop someone reads what power the amplifier is recommended for? You just have to know a little about it ...

Well uDimension is also rather not toys straight from the bazaar, this topic somehow oscillates around the evident class of Hi-end, where you are already looking for nuances and you have to be out of the stage a long time ago ... a lot, colorful, loud ... and I warn you as experienced, a heart can hurt when you have to buy an ugly amplifier and spend as much as a few pieces of a beautiful colorful "thud".
I wish you a nice day .

But who will tell me what is the meaning of stronger speakers than an amplifier? It is like throwing away a part of the money for this speaker because it will not have the effect it should be, because the speaker will not play 100% possible.
And gain is there to be able to use it skillfully.
I have a weaker taste at home than the speakers, but you learn from your mistakes
I have a 2x25cm sub, each connected to one channel. I wanted to check it out. So first a listening session, a careful inspection of the deflection, and so on, 55W RMS per speaker. Later, each of the speakers connected to the bridge was 170W RMS per loudspeaker and I have to say that with the same music, the same volume level, you could see stronger tilts and the sound may be unknown, but it was somehow fuller and more precise.

You say it is better if the power of the amplifier is higher.

I would like to define it better.

Is it the volume alone?
about dynamics?
for strength?
detail of sounds?
contrast?

what's really going on.
What do we gain by switching the speakers from weak to strong amplifier?

Some time ago on this forum wrote,
that everyone cares to avoid distortions
on the amplifier ...
forgetting about distortions in the speakers ...

Are the distortions on the speakers less important than those on the amplifier?
Which distortions decide about the final effect - the sound?

Isn't it that if we give the amplifier a rest
are we going to tire the speakers?

Well, if we consider two amplifiers of the same class and more powerful. By changing them, we will mainly gain in dynamics, we will be able to partially listen louder, but here is also the limit of the speakers themselves. We will also benefit from the control of the sound itself, especially on subwoofers, the sound will be more "accurate". Some loudspeakers need to get the right amount of power to play what they can, but it doesn't exactly translate to a certain amount of watts from the specification, because other factors also affect it.
The last two questions I do not understand, what kind of distortions on the loudspeakers, probably the loudspeaker does not generate them by itself.
And the last question is no longer a mystery.
I see in general that you want a little too much to define everything in words and rules. Unfortunately, it is not that simple, there are some basic rules, but unfortunately there are no simple and easy solutions. There are many factors that affect sound quality and many variables.

Continuation of my considerations
There is one thing that puzzles me ...
Everyone agrees that the amplifier
it must be stronger than the loudspeaker.

I have been browsing this forum for a long time.
I am asking for any advice on the selection of components.
But in most cases:
Loudspeakers with higher power than the amplifiers are selected
- "should pull gently '

Nobody recommends the popular junior
Dark blue helix or el compa
and always (if it's unlimited it ends in es-6c (you know what I mean)
the same is with the imme amplifiers ...
After all, according to earlier thoughts, he would have better control over Helixes than powerbasses ...
What amplifier will this Helix be better than the Powerbass?

What am I striving for ...
Do you always have to be guided by speaker power?
Can a hi-end loudspeaker with a power three times greater than that of the amplifier (not reaching its maximum capacity) sound from a loudspeaker properly selected for the system?

"should pull gently" "- this may only mean that the speaker will not show its capabilities in 100%, only e.g. 90%, which for me is a complete nonsense (especially with middle-class and higher-class equipment).

"After all, according to earlier thoughts, he would have better control over Helixes than powerbasses" - in this situation it is better to give up "excess power" and buy a set with a better tweet, i.e. we choose the lesser evil. Excess power is especially required for the Sub drive, in the case of kick-bass it may not be there, but the "strings cannot be pulled" (maximum 20% stronger speaker / kick than the channel that drives it). It's my opinion.

Buddy, the condition for the power requirement for the loudspeaker must first be met, and then you look whether it is Focal UTOPIA or Blaupunkt :)

In the case of the tweeter drive, you can afford greater tolerances of the rated power of the main to the channel that drives him ... my opinion again.

... everyone has a different one: lol

"a maximum of 20% more powerful speaker / kick than the channel that drives it" As I said, making such rules is completely pointless. Amplifier, not equal to an amplifier, even if they have similar powers. Likewise, the power stated by the loudspeaker manufacturer does not have to match the power requirement of such a driver. But I agree, the sub needs power the most, and with a tweeter, power is of marginal importance.

I also once had a problem that I did not know whether the speakers were stronger than the amplifier or vice versa, but it was enough to sit on the forum a bit, read the posts paying more attention to what they say "knocks down, Sylwek, crazy_88" because they have an idea about CA and everything is clear to me now.
The amplifier should be more powerful than the speakers
The pros are - good control, you can get the best out of the loudspeaker.
The downside to mindlessly setting the gain is you can burn the speakers.

When the amplifier is weaker than the loudspeaker, it will not be able to drive it well and will not play at 100% of its capacity, and you can also burn it by turning the gain to the maximum when a rectangle appears on the output.

I don't understand why people want to turn this gain all the way ... because then you can't talk to people in the car and if you drive alone, your head starts to ache after some time.

A rule that I have always followed, an amplifier of the same power or more powerful than the speakers, adjustments to a maximum of 70% of the performance. I avoid distorting the signal by the loudspeakers, the amplifier does not work at its maximum and does not give a rectangle. When I have a mindless type who turns the gain, I remove the potentiometer and solder the resistors so that I won't be tempted.

There must be a power reserve on a boost
Less probability of overdriving it (as mentioned by [b] kortyleski [b /])

But there is also the other side of the coin, folks which I have recently had the opportunity to convince myself of ... it's 50W of good, decent RMS, but somehow it ... is not equal to other 50 Watts of equally certain (company) RMSu, this is where the nuances begin and ... looking for it something in CA something that never according to. The "dry" data of some companies will never be included because ... THIS MUST BE DISCOVERED BY YOURSELF ... unfortunately, sometimes this search lasts forever and all in all ... this magnet, which is a kind of drug, has in all this entertainment game.
I wish you a quiet night.

powers with powers, but there are also parameters of the amplifiers that are equally important, e.g. df probably that's why 50W of pure rms is not equal to 50W of another manufacturer btw, I am also of the opinion that (at least when it comes to the front system) the power of the amplification should be at least equal to the power of the speakers .. and as for the bass speakers, you also need to be guided by the housing in which the loudspeaker will play and of course the user's common sense .. but in general "never enough power"

I will not create a new topic, I will write here ...
I have a 20 watt Impetence 3 Ohe amplifier and I will hook 20-50 watt speakers to it. Impetance 4-8 Ohe all will be fine. Nothing will burn?
