why to combine the speakers with the amplifiers


Have you set out to upgrade your audio system and determined that purchasing an amplifier would be a smart investment? Prior to ordering, choose the most critical factors to examine to ensure the amplifier is a good match for the speakers.


It is not sufficient to purchase a pair of high-performance speakers and a high-quality amplifier. To obtain a high-quality sound, you must also ensure that the two components are compatible and operate together properly. Consider the following when combining speakers and an amplifier to create an outstanding sound.

Check for impedance

Impedance is a term that refers to the resistance of electrical components to the passage of current. It is measured in ohms and is one of the characteristics to consider when purchasing speakers for an existing amplifier or vice versa.

Compatibility is not a tough concept to grasp. The fundamental guideline is to avoid pairing a higher impedance amplifier with a lower impedance speaker, for instance, a 6 ohm amplifier with a 4 ohm speaker.

It is important to understand that when using speakers with a greater impedance than the amplifier, the transmitted power is correspondingly reduced. For instance, if you connect two 8-ohm speakers to a 1.4kW amplifier, each device would receive 360W of power, whereas two 4-ohm speakers will receive 720W of power.

Select a little more powerful amplifier.

To get the most out of a pair of speakers and amplifier without overloading any of the components, it is a good idea to consider power compatibility. Identifying the appropriate models needs assessing the indication that indicates the continuous power output of the amplifier, often known as RMS power. Additionally, the technical descriptions use the term “peak power” or “Peak power,” which refers to the greatest amount of power that the device can deliver at any particular moment. However, it is a less significant indication.

Another critical factor to consider is the continuous power available to a channel at a given impedance value. For instance, an amplifier can deliver 100W at 8 ohms or 150W at 4 ohms, depending on the speaker impedance.

Speakers often indicate the minimum or maximum permitted power in their technical presentation, a value that may be used to help you in selecting an appropriate amplifier.

You may connect a 100W amplifier to 150W speakers and they will function well as long as the system is not used at full volume for an extended period of time to prevent overloading it. The same caution is advised in the reverse situation, when a more powerful amplifier is used with speakers that require less watts.

The conclusion to draw from this is that it is prudent to select an amplifier with somewhat more power than the speakers require, in order to have a supply of resources for a high level, but to utilize the speakers sparingly. However, avoid extreme discrepancies, as overwhelming the speakers might result in their failure.Why to combine the speakers with the amplifiers

Determine the decibel level required.

Under the guise of sensitivity, indicated in decibels, is a feature that will pique your interest: it indicates how loud the music sounds at a certain system power level.

This metric is typically tested at a power of 1W or 2.83Wrms. While the majority of speaker types have a sensitivity of 85 to 95 decibels, there are others that have a range of 95 to 110dB.

To grasp the concept of combining speakers and amplifiers in terms of sensitivity, it is necessary to realize that the power required to add each extra 3dB to the base level requires a doubling of the current power. For instance, if you have a speaker with an 85dB sensitivity, you will require 1W to operate it at this level.

To achieve 88dB, 2W is required, 91dB requires 4W, 94dB requires 8W, and 106dB requires 128W; these numbers are computed based on the sound perceived at a distance of 1m from the speakers.

According to studies, the perceived loudness falls by 6dB every time the distance between the speaker and the listener doubles, which implies that a speaker that generates 85dB at 1m would generate 79dB at 2m and 73dB at 4m. 512W is required to hear 94dB at an 8m distance.

When selecting system components, you can go for higher-sensitivity speakers and a lower-power amplifier, or for lower-sensitivity speakers and a higher-power amplifier, based on available offers, budget, and personal preferences.Why to combine the speakers with the amplifiers

Analyze the spatial framing

The amplifier and speakers you select to complete an audio station are also determined by the space in which the system will be used. If it is to be placed and utilized in a large room with a high ceiling, it will undoubtedly require a more sensitive version of the speakers and a more powerful amplifier capable of effortlessly covering the space without succumbing to overload distortions.

On the other hand, if you are searching for an audio system for a standard apartment room, you may be able to get away without an amplifier and a decent pair of speakers. You may easily utilize speakers with a lesser sensitivity in this context, and if you do decide to use an amplifier, a medium or low power one would suffice.

For more technically savvy consumers, there are computers on the Internet that will determine the ideal settings for such an audio package based on a range of criteria, beginning with the height and surface area of the room.
