Choosing Suitable Speakers for Tower: Comparing 20w 6ohm, 30w 8ohm, and 2x50w 6ohm Models

The factory speakers for the tower were 20w 6 ohm and 30 w 8 ohm. Same in the second column. I found 2x50w 6ohm speakers whether they will work and whether they will not destroy the amplifier. If not these, what are they?

Start again and write what the tower is (name, model, etc ...) and the same with the speakers. And write why you want to change the "factory" speakers?

I do not know what kind of tower it is, I know that it is Philips, I do not know the model in this tower, there were two speakers, the tower has a 2x50 watt amplifier, but I do not know how it is with ohm. In these loudspeakers there were 2 drivers, one mid-tweeter 30 w at 8 ohms and the other 20 woofer 6 ohms. And I want to buy new ones because the original ones don't work. It was destroyed by children. And I have a question, I have an eye on the speakers for this 2x50 w 6 ohm tower whether they will work or not

Doesn't this tower have a nameplate?
Just provide her picture.
Moreover, loudspeakers with higher impedance can be safely switched on
So instead of 6 ohms, you can safely turn on 8 ohms, you will only lose a little power.

However, this is a tower, such as the Philiss AS440 / 20H tower, 80 watts, so how to choose the speakers

So what speakers to buy ??

6 ohms and minimum 20W
The power can of course be greater, but there is no point in overdoing it.

So for 70w I can only use 20w?

70W, it is off-grid it has. This power is distributed throughout the tower.

It can be bigger, but this tower has a power of only 2x10 W

Let me elaborate, because as I can see the Author has no idea about it ...:
The power given as POWER CONSUMPTION is the total power that the tower can draw from the mains at maximum control. This power is actually the power of the power supply - the transformer that is to power all the tower blocks; tuner, tape recorder (if available), CD (if available), all intermediate circuits (tone control for example) and power amplifiers. The latter, depending on how they are built, have a certain efficiency - in most cases in this type of towers this efficiency is approx. 60% - so after adding up all receivers (modules / components) it comes out (as my colleagues wrote above, and the manufacturer also provided in the specification) 10W sine per channel. The musical power, in turn, depends largely on the power supply itself; on its ability to give a certain current over time. The weaker the power supply, the greater the music power (in this case, the power is 20W per channel, but usually the music power does not exceed 150% of the sinus power), because the voltage drops by some amount during a greater load.
Further - these 10W are the "base" - power that can be considered the minimum power of the speaker units (speakers). There is nothing to prevent the power of the speakers / speaker units from being greater - the amplifier will give it back as much as it can - the speakers will simply operate at a power lower than their nominal power. It is important (and you should always remember this!) That the resistance of the loudspeaker should not be lower than the resistance specified by the manufacturer of the tower - lower resistance means higher current flowing through the amplifier circuits (and of course the power supply), higher losses in the power amplifiers, higher temperature and the real possibility of damaging the power amplifiers (power amplifiers).
In this case, the manufacturer gives a nominal load resistance of 6 ohms - this is the so-called "golden mean" - resistance is often given as nominal resistance in small towers, home theaters, etc., to somehow allow the use of resistance in the area indicated. Unfortunately - it is also often the resistance resulting from the power output capacity of the amplifier system used to obtain the maximum power that can be "squeezed" from the amplifier system and connecting a lower resistance may overload the amplifier and possibly damage it ...
On the other hand, connecting columns with higher resistance does not cause any dangers - at most, the power will drop slightly.

Are you talking about a bare speaker or a column? Remember that a speaker without a housing adapted to it will not sound properly.

Thank you very much, I don't know anything about it yet and I'm interested in it. I found the loudspeakers, but they are probably too strong. But why there were 4 original speakers in this tower (2 columns)
Two 30w 8ohm mid-tweeters and two 20w 6ohm woofers?

There are no "too strong" columns. I was writing:

The loudspeaker consists of several speakers - the simplest version is a woofer and a tweeter. As their names indicate, they are designed to reproduce certain frequencies. To prevent the high frequencies from reaching the woofer and the low frequency tweeter, a crossover is used - a simple electronic system (sometimes only one capacitor, sometimes several capacitors and several coils - depends on the type and the speakers themselves), whose task is to divide (separate) the signal from the signal music in such a way that only the frequencies intended for them can reach the appropriate speakers. Due to this crossover, the resistance and power of the loudspeaker are determined ONLY by the woofer (one, sometimes more); And this one is appropriate in your case - 20W and 6 ohms. In other words - the tweeter does not affect the electrical parameters of the loudspeaker.

With a little persistence and focus, you will find most of the issues that interest you and explanations for many questions.

Thank you for your answer. So it is so that the current goes only to the bass speaker and from this speaker it goes through the capacitor to the tweeter, it means that the channel is 20 watt current, do I still not understand something?

You more or less start catching something. But I asked - watch (listen to comments) the movie from the link.
Best of all.

I watched the movie how to choose the speakers for the amplifier there was an example that the amplifier had 2x30w and that the best speakers would be from 50 to 100w, how would it be for my amplifier?

From 20 and up.

will such speakers be good?

Normally I would say "keep away from this junk (Voice Kraft)", but ... they will fit this tower. The problem is that when you ": grow up" to change equipment to a better speaker, you will also have to replace ...
These loudspeakers have one advantage (not the worst of sound quality) - They are new and quite elegant ...
It is not known what headphones are free, but judging by the speakers - also not very good ...
