When evaluating CMRR for your audio system, it’s important to determine what the optimal value is. In general, CMRR is the lowest effective level, but it is possible to improve performance by several factors. For example, CMRR can help prevent noise from a speaker by using differential signalling. This technique involves grounding cables with multiple points. In addition, grounding cables should be combined with low-frequency treatment. There are several methods for grounding cables, including mesh and star grounding. Hybrid grounding, which couples shield points to ground through capacitors, has also been a subject of debate for some time.

The CMRR test setup consists of a buffer amplifier that drives a Vcm signal through low-value resistors to the DUT’s inputs. A current source with a bandwidth of 100MHz drives the inverting input of the DUT and produces feedback. The controlled current source sees the low-value resistor connected to this inverting input as a load. CMRR measurements can be extremely challenging, so it’s essential to have a well-matched system.

To achieve the CMRR of an audio system, a high-end mixing console can cost over a million dollars. Its transformers cost thousands of dollars each, and its CMRR was -115 dB at 50 Hz. By comparison, a cheap mixer can only manage a minus 70 dB CMRR at low frequencies. This level is acceptable for a touring rock band or a small nightclub.

A high-quality CMRR is essential to avoid interference from external sources. An amplifier with a high CMRR should have a high input impedance. Otherwise, a high-quality audio system would lack a good signal. In the end, a good CMRR is an important factor when deciding which system is right for you. If you want to get the best sound quality, you must choose a system that can eliminate the most noise.

Dynamic range

The dynamic range of an audio system measures the difference between the peak level of the sound and the average level. This feature is not always perfect, however, because recording techniques can affect the sound quality of a recording. In addition, this metric can be misleading as it does not capture small details that are buried in the recording. Regardless of the source, it is important to consider DR when choosing an audio system. However, if you’re in the market for a new audio system, there are many ways to determine its quality.

The dynamic range of an audio system can be measured in dB. Essentially, it’s the difference between the loudest signal level and the noise floor. In audio systems, this metric is also called signal-to-noise ratio or SNR. The higher the dynamic range, the better, and more importantly, the sound quality will be. Typically, the dynamic range of an audio system is between 135dB and 134dB.

This measurement is often confused with signal-to-noise ratio (SNR). SNR, or signal-to-noise ratio, refers to the available range between the normal operating level and the noise floor. Dynamic range, on the other hand, refers to the maximum range of a unit. For analog systems, this specification is always a moving target. However, most audio professionals agree that 1% to 3% distortion is acceptable.

Dynamic range is an important metric when comparing audio systems. A higher dynamic range means better sound quality, which is necessary to avoid distortion and deterioration. In addition to SNR, dynamic range also reflects the noise reduction of a system. Higher SNR levels mean more accurate reproduction. However, this does not mean that you should pay extra for a higher SNR. In reality, higher SNR levels can increase your system’s SNR and dynamic range.


There are many types of speakers, but they all have one basic function: reproducing sound. Speakers are electroacoustic transducers that convert an electrical audio signal to sound. Speakers are made up of three main parts: speaker drivers, enclosure, and electrical connections. Speaker drivers are essentially linear motors attached to a diaphragm. They couple motion of the motor to the motion of air, and the resulting sound is amplified by amplification.

The SPL (sound pressure level) of a speaker can be measured by the manufacturer. This number is commonly expressed in decibels (dB) and is measured at a single meter. The sensitivity of the loudspeaker is also important. A higher sensitivity means that a speaker can handle twice as much power as its counterpart. However, a higher sensitivity can cause distortion. A tweeter can be damaged if a speaker is not designed for the frequency range it is intended to reproduce.

Two basic types of speakers can be classified as planar or acoustic. The former radiate sound uniformly in low frequencies and focus it into a narrower angle as the frequency increases. Planar speakers have a long wavelength and a large directivity, but they are less directive. Smaller drivers can achieve similar results as large dynamic loudspeakers, but their directivity is narrower. One example is a planar magnetic loudspeaker without a baffle.

Directivity and room reflections are also important factors. Directivity affects the frequency balance of sound and how the speaker system interacts with the room. Too directive speakers create a shallow reverberant field and lack treble. However, speakers with rapid increases in directivity at high frequencies may give an illusion of treble. They can also give a false impression of bass. Regardless of the design, there are different types of loudspeakers available.


When you’re considering a new audio system, you may have considered adding a subwoofer. However, a bad setup or a poor design can have a negative effect on the quality of your subwoofers. REL subwoofers, for instance, use a high-level signal to improve timing from the amplifier’s speaker output terminals. The built-in amplifier also gives your subwoofers more precise feedback about the sonic signature of the amplifier.

A subwoofer contributes to the performance of your entire audio system in many ways. For one, it relieves the full-range speakers of low-frequency material. That means these speakers can concentrate on the higher, mid-range frequencies and not the lower, unintentional frequencies. Also, subwoofers reduce distortion, which is caused by large cone/diaphragm excursions. Moreover, they can help you make better use of your audio amplifier by lowering the power requirements.

In addition to the volume control, subwoofers have crossover frequencies. These frequencies control the range of audio the subwoofers produce. The crossover frequency is the number of Hz above which the subwoofers can produce a certain range. To adjust the crossover frequency, you should listen to music that has a wide range of frequencies. A good example is classical music, which contains many instruments. Ultimately, it’s important to ensure that your audio system’s subwoofers are properly tuned.

To improve the bass, try placing the subwoofer near the walls. This is because the sound from the subwoofers will reflect from the walls, increasing the bass power. You can also place the subwoofer under furniture. Coffee tables have cavities that can accommodate subwoofers. This placement will bring the subwoofer closer to the source. But always remember that the closer you place the subwoofer, the greater the bass.


Tweeters in an audio system produce a lower level of sound than other types of speaker drivers. This type of speaker is best suited for speakers that are pointed directly at the listener, as their cone is small and produces less sound at angles. To choose the right tweeter, you should know the size of the driver and the rated impedance of the amplifier. Tweeters have a range of output sensitivity, with a higher sensitivity being better.

There are many different materials used for tweeters, including silk and metal. Silk is the most common, and produces a mellow, balanced sound. Silk tweeters do not have a high degree of accuracy at high volumes, however, and they don’t have the best dampening properties. However, synthetic tweeters can be reinforced, allowing listeners to crank up the volume while maintaining high quality. Metal tweeters have the highest sensitivity and durability, while textile tweeters are the most expensive.

In an audio system, tweeters are an essential component of the sound reproduction process. Their job is to help amplify sound in an audio system, while ensuring that every detail is clearly heard. The cone tweeter is one of the least expensive types of speaker, and has a wide frequency distribution. This wide distribution enables the listener to focus on the frequencies they find most pleasant. However, some manufacturers use a whizzer cone design, which thins out the distribution while spiking high-end sound. These designs aren’t recommended for accurate sound reproduction.

Tweeters in an audio system can also be mounted surface-mounted in the vehicle. This method is useful when mounting tweeters in an area that is difficult to reach. Unlike the midrange drivers, tweeters are not as demanding in terms of placement. Because of this, tweeters must match the rated impedance of the amplifier in the audio system. However, this is not a common practice with premium sound systems. Generally, tweeters are mounted in a fixed position in an interior door panel.
