These are meant to be matched with speaker impedance ratings for maximum performance. Therefore, if you have a 4-ohm speaker, you will need to connect it to 4-ohm amplifier output. A 6-ohm speaker requires a 6-ohm amp and an 8-ohm amp an 8-ohm speaker and so forth.
This speaker-amplifier matching is very important as it helps both electrical devices to operate optimally and be able to deliver maximum audio quality. It causes sound distortion which leads to poor sound quality and introduces more chances of damaging circuits of the amplifier. The problem is more aggravated when you listen to loud music because of the increased power demand.
Now that you understand how speaker impedance affects their interaction with amplifiers, separate them in terms of which one is better. However, as already mentioned, the amount of ohms or impedance ratings of a speaker is just a value that generally determines how much current the speaker draws from an amplifier and not how much sound it delivers nor the quality of sound. The quality of sound given by a 6-ohm speakers and 8-ohm speakers is therefore expected to vary considerably depending on the various speaker drivers used in both.
It is true that the sound quality does not directly depend on speaker impedance. As a characteristic of the speaker, power amps should therefore be in a position to handle it. However, because speakers operate at very different frequencies, no single speaker will have the same ohms value at all the frequencies. For instance, an 8-ohm speaker will sometimes be 5 ohms or sometimes even much lower. Looking at the speaker impedance curve, it is clear that speakers, whether 6 ohms or 8 ohms, play at very variant impedance levels while at different frequencies.
This therefore means that depending on the frequency, the impedance of an 8 ohms speaker for instance has chances of falling below 8 ohms and even more chances of rising well above that.
This value is therefore just the average and not a fixed impedance value for any given speaker and only means that the speaker will not draw a constant electrical current from the receiver during operation. The reason we care, beyond it sounding bad, is that our speakers have physical components that react to the audio signal.

Ben Davis February 19, What amplifier do I need for 6 ohm speakers? How many watts is a 6 ohm speaker? Will 6 ohm speakers work on 8ohm amp? How do you match amp power to speakers? Is 20 watts loud for a TV? Does higher RMS mean better sound?
Do speakers sound better with more power? Does more speakers mean better sound? A common method of changing speaker impedance is by adding another speaker, either in series or in parallel with the existing speaker. While this will change the output power of the amp, the speakers will share that power. Most modern amplifiers will, if they are overloaded, either turn themselves off or reduce the output to protect themselves.
However, it is wise not to rely on this self-preservation circuitry, best to design your system conservatively. Keep in mind that all this is describing the maximum power output of an amplifier.
To double the volume you need around ten times the power. If you need maximum level from your speakers, pay attention to the sensitivity in the specifications. For more details on this see the article Understanding Speaker Sensitivity. While speaker impedance changes amplifier power output, it is not a major consideration for most users. It only becomes relevant when running your amplifier at full power, and then it is best not to run it too close to its design limits.
Never use a speaker or speakers below the minimum impedance the amplifier is designed for. If you hear any distortion, it is an indication that major trouble is just around the corner — turn the volume down, eliminate the distortion and consider a redesign of the system.

Yet, it is often the first and possibly only parameter Understanding Audio Understanding Speaker Sensitivity. Speaker sensitivity is a measurement of how well a speaker converts the amplifier power to to acoustic energy. In others words, how loud the Often people are wanting to add speakers to their amplifier to increase power.
However, in most cases, adding speakers will reduce the power in In fact, your amplifier power could be nearly half or double its capacity - depending on the impedance Home Speakers Understanding Speaker Impedance. Speaker impedance is often presented as a complex subject and therefore is either ignored or misunderstood. A basic understanding of speaker impedance is not Distributed speaker systems are also known as " volt line" or "70 volt line" speaker systems. They are used extensively where multiple speakers are Understanding Audio Double amplifier power does not double the volume.
This article logically shows the relationship between amplifier power, SPL and loudness. It includes a level difference exercise and a gain calculator. Understanding Audio Understanding Acoustic Feedback. Acoustic feedback it that annoying loud continuous tone you get when the sound system is not set up or operated properly. Acoustic feedback can Understanding Audio Understanding Audio Frequency.
Every sound we hear is at a certain frequency. When we say someone has a deep voice, we are describing a voice producing low Understanding Audio Understanding Decibels part 2. In the first article we saw that a decibel is not a fixed unit, rather, it is a ratio between two levels. A decibel Understanding Audio Understanding Decibels part 1. Decibels are widely used in audio, and often misunderstood.
These articles give a practical understanding on using decibels in audio work. But first, some For example, when the battery reaches 3. The next thing you will probably want to know is the power generated at the coil, or wattage. Just multiply the current in your circuit by the voltage applied:. So that 0. You can see that as the resistance of your coil increases, current and wattage will both drop. Since you know that the battery CDR is 10 amps, you might want to target 9 amps in your calculation, to give yourself 1 amp of headroom.
You also know that your max voltage will be 4. So the calculation goes like this:. The result tells you that your safe lower limit with the amp battery is 0. Of course, if you have a amp battery, your low resistance drops to 0. Finally, and probably not as useful to us, using the triangle you can solve for voltage in a circuit, as long as you know the values of the other two variables.
These will allow you to figure out the current your coil will draw and the wattage that will result. As you increase resistance, current and power will drop off. If you decrease resistance, current and power will increase. The resistance formula allows you to calculate a safe low resistance based on the CDR of your battery. There are other considerations like coil ramp time and the heat of your coil that are determined by wire gauge and mass.
One final, and critical piece of advice: ALWAYS assume that your battery voltage is the equivalent of a fully charged battery: 4. People will argue that the coil will never see that actual battery voltage due to voltage drop within the mod, but to be safe, ALWAYS use the full theoretical battery voltage at full charge in your calculations.
If I use vtc4 for mech mods, using dual coil, what is the best coil appropriate to use? If i use 24g fuse clapton with 5 loops 33mm guide is that safe, can you explain it?
