What is a 12dB crossover?

What is a 12dB crossover?

Electronic crossovers commonly have a 12dB/octave slope. This means that every time the frequency of the audio signal is changed by a factor of 2 (one octave), the level of the audio signal will change by 12dB.

What is the best crossover slope?

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 does 24dB octave mean?

A means of measuring the slope or steepness of a filter. The gentlest audio filter is typically 6dB/Octave (also called a first-order slope). Higher values indicate sharper filter slopes. 24dB/octave (fourth order) is the steepest normally found in analogue audio applications.

How do you calculate speaker crossover frequency?

In technical terms, the crossover frequency is found by using the -3 decibel (dB) point from the output of a crossover circuit. In electrical power terms, the 3dB volume reduction point is the frequency at which the power to the speaker is reduced by 1/2.

What is 12db octave?

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). Vintage Arp, Korg, and Oberheim instruments often featured 2-pole filters, often resulting in brighter sounds when compared to those with 4-pole instruments.

What is the best crossover frequency for home theater?

The recommended crossover frequency is 56-60 Hz (high pass). At this frequency, low-end bass, which can cause distortion, is filtered out.

What is a good crossover frequency for home theater?

80 Hz
The most common crossover frequency recommended (and the THX standard) is 80 Hz. On-wall or Tiny ‘satellite’ speakers: 150-200 Hz. Small center, surround, bookshelf: 100-120 Hz. Mid-size center, surround, bookshelf: 80-100 Hz.

How do you choose a crossover slope?

Post by TKO on Sep 16, 2013 at 8:57am

  1. Choose a CO slope of 12 dB.
  2. Choose a CO slope of 24 dB.
  3. Try different crossover points between 40hz and 80 or 90 hz, depending on your speakers/sub (keep the CO and slope the same)
  4. Try different crossover slopes for the mains and subs.

What is 12dB octave?

What is the difference between 12dB and 24dB filter?

The difference is in the name, literally. 12 and 24 represent what the filter does to frequencies past the cutoff point – a 12 db filter will attenuate frequencies past the cutoff by 12 decibels for each octave above the cutoff. A 24 db filter will do the same thing but by 24 db for each octave past the cutoff.

What should I set my speaker crossover to?

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). Once again, play some music. But this time, slowly turn up your receiver’s volume until you hear it begin to distort.

What is a good frequency response for speakers?

What frequency response is good for speakers? The preferred frequency response for speakers is 20 Hz to 20 kHz. The human audio spectrum ranges from 20 Hz to 20 kHz. Speakers should be able to produce sounds in this range.
