What is a 12dB slope?

What is a 12dB slope?

12dB/octave These have a 12 dB/octave slope and can have Linkwitz-Riley or Butterworth implementation. This order is commonly used in component set passive crossovers as it offers a reasonable balance between complexity, response, and high frequency driver protection.

What is 12dB octave?

This format of numbers and abbreviations (dB/oct = decibels per octave) is often used to refer to the frequency response behavior of a filter. A 12dB/octave filter is often referred to as a “two pole” filter (as each pole of a filter’s design results in 6dB of attenuation).

What slope should my subwoofer be?

Recommended Starting Points: Tweeters – High-Pass Filter = 5,000 Hz (12 db or 24 db Slope) Midrange – Band-Pass Filter = 80 Hz HPF & 5,000 Hz LPF (12 db or 24 db Slope) Subwoofer(s) – Low-Pass Filter = 80 Hz (12 db or 24 db Slope)

What does 6dB octave mean?

A 6dB per octave slope is useful for gentle shaping – a little less bright, a little less heavy, depending on whether the filter is high-pass or low-pass. 12 dB/octave is more useful in a creative musical context.

What is LPF slope?

Low pass filter. A filter which attenuates frequencies above its cutoff frequency (which is the point where the signal is 3 dB down). The slope of the filter is the rate of attenuation, i.e. 6, 12 or 24 dB per octave.

What is the best crossover slope?

What is a good crossover slope for car audio and home audio? However here the best crossover slopes for most people: A 12/dB setting is good and will do the job in most cases for subwoofers (low-pass) and full-range speakers (high-pass).

What should LPF be set at?

As a general rule, the Low-Pass Filter should be set at a value approximately equal to (or below) 70% of your main speaker’s lowest frequency response.

What is the ideal crossover frequency?

80 Hz
Set the crossover point around 10 Hz below the lowest frequency your speakers can produce without issue. (keep in mind that the most common recommendation for crossover frequency is 80 Hz).

What does 12Db per octave in sound mean?

The smallest amount of electronic components that makes a low or high pass filter creates a slope of 6 dB per octave. That’s called a “one-pole” or “first order” filter. IF you double the components, you create a 12 dB per octave low or high cut filter and that is called “two pole” or “second order”, and so on.

How to calculate slope of a line m = 2?

m = 2 Slope calculator uses coordinates of two points A(xA,yA) A (x A, y A) and B(xB,yB) B (x B, y B) in the two-dimensional Cartesian coordinate plane and find the slope coefficient of a line that passes through A A and B B.

What is the slope of a line from left to right?

Positive slope m > 0 m > 0, if a line y = mx + b y = m x + b is increasing, i.e. if it goes up from left to right; Negative slope m < 0 m < 0, if a line y = mx + b y = m x + b is decreasing, i.e. if it goes down from left to right;

What can you learn from a slope calculator?

The slope calculator, formula, work with steps and practice problems would be very useful for grade school students (K-12 education) to learn about the concept of line in geometry, how to find the general equation of a line and how to find relation between two lines.
