#1 this is my room measurement, with No Smoothingspeaker : modified custom PMC with sub. bryston 3 ampbelow 100hz is my sub. without a sub, it looks similar, with less bass as expected...i have some basic treatment. no bass trap at corners at all. as i have door, fireplace etc at corners... so its hard to place them... how does it look, how can i improve, what is the range i should be getting in to...EDIT: this is left ch only. right ch looks similar, #2 1/12 smoothing looks like this #3 I don't use FuzzMeasure as all my computers are PCs...From what I see in the first response curve, you've got a problem at 1K and then to all the above harmonics (2k,3k,5k...). First I thought it was a dip centered at 1Khz due to some wall reverberation but the surprising thing is that the 2k deep should be more deep than it is.What are the crossover frequencies ? Especialy the mid/high ? #4 crossover frequency is 3khz. edit : above 4k is mostly my work_bench first reflection... without work_bench its smoother, also taped a tissue on tweeters. , hi frequency rolls of nicely above 4k now. #5 As the crossover frequency is 3k, what I can say about the curves is:- Try to reverse the polarity of your tweeter. It can solve the dip at 3k I didn't understand. If it's worse, it's maybe because of the tweeter response.- Find the wall that make the 1k dip and put some rockwool or a schroeder diffusor on it. 1KHz wave length is about 34cm. There's a wall somewhere that reflect the sound creating the dip at 1kHz, then 2kHz, then 4kHz, then 8kHz...Tell if you find something.Can you post a quick drawing of your work place with some distances ? #6 hey lolo-m , thanks so much... i actually reversed the polarity of my tweeters, while ago, i had a really nice response, as you guessed... dip disappeared, i then reversed back to original polarity, in_case i would damage the tweeters ???i suppose, its fine to use tweeters in reversed polarity ?EDIT: basic drawings on the way #9 plan3i am facing the low wall side, Nora Well-known member #10 Any chance to measure with other monitors?Even cheap bookshelf speakers should reveal whether this is a crossover or tweeter polarity issue.You could also try moving the measurement mic a few centimeters/inches to rule out any close reflections from console or desk (when the frequency of the notch changes)If this gets sorted out, I would focus on the low end of the spectrum. There's a problem around 50Hz (length and width?) 74Hz (width) 125Hz (width and height)You can calculate these frequency's into wavelengths and understand which walls are causing standing waves. But there's nice little java scripts out there that do it for you, with all associated harmonic multiples. Google: room mode calculator (or if you have an iphone/touch, I use AudioCalculator) With an angled roof it's much harder to calculate

Tips for Setting the Proper Crossover Frequency of a Subwoofer The crossover frequency of your subwoofer is the frequency at which your speakers start to roll off and your subwoofer kicks in with LFEs and bass notes. Most modern AV receivers feature an auto EQ program that will assign the proper crossover frequency automatically based on the capabilities of your loudspeakers. It’s generally best to leave these settings where they are.If you’re using an AV processor, preamplifier or a DSP subwoofer to adjust the crossover frequency in a two-channel or surround sound set-up, here’s a few tips to get the best performance possible. As with any bass management functions, it’s helps to do some critical listening and experimentation to achieve the best sounding results. Check out the entire SVS Subwoofer line-up to choose the subwoofer that is best for your TV/movie viewing. If you know your speaker’s frequency range, set the crossover point roughly 10 Hz above the lowest frequency your speakers can handle cleanlyThe most common crossover frequency recommended (and the THX standard) is 80 Hz.The numbers below highlight general guidelines for speaker/subwoofer crossover frequenciesOn-wall or Compact satellite speakers: 150-200 Hz.Small center, surround, bookshelf: 100-120 Hz.Mid-size center, surround, bookshelf: 80-100 Hz.Large center, surround and bookshelf: 60-80 Hz.Very large center, surround, bookshelf: 40-60 Hz.Tower speakers with 4”-6” woofers: 60 Hz.Tower speakers with 8”-10” woofers: 40 Hz or Large/Full-Band (i.e., full-range).If you’re unsure about your speaker’s ideal crossover frequency, try our SVS Subwoofer Matching Tool, which will recommend the ideal SVS subwoofer for your speakers and tell you the best crossover frequency.Listen for a smooth transition between speakers and subwoofer. Ideally, the blending will be so seamless, you won’t be able to localize the bass and everything will play in unison.If you’re noticing a bass bump at the crossover frequency, try adjusting the volume control to match the output of your main speakers.For a deeper dive into crossover frequencies, check out our Digital Bass Management Primer.SVS Ultra, 4000 and Plus Series Subwoofers feature powerful and sophisticated Sledge DSP amplifiers that allow you to adjust crossover frequency, room gain and other settings directly through the subwoofer.If you have any questions about setting the crossover frequency or system set-up in general, leave it in the comments or contact our Sound Experts at custservice@svsound.com.SVS makes a variety of powered subwoofers with DSP amplifiers to fit every room, audio system and budget.

How to calculate crossover frequency

DIY Audio Speaker Crossover Wiring Guide / FAQ See the Crossover Example Tutorial for more information. What is a crossover? People can hear sound frequencies from 20-20,000Hz. There is no one speaker capable of producing all frequencies throughout this range. Therefore, multiple speakers must be used. Usually, it is damaging for a speaker to produce frequencies lower than what it was designed for. Also, if two speakers produce sound at the same frequencies, then the sound at those frequencies will be louder. For these reasons, some type of circuit is necessary to make sure that each speaker only produces a certain set of frequencies. That circuit is a crossover. No crossover can completely block out all frequencies beyond the crossover point. Instead, it filters the frequencies in greater amounts as the frequency moves away from the crossover point. How fast it filters the sound is determined by the order of the crossover. A 1st order crossover filters 6 db/octave, a 2nd order 12 db/octave, a 3rd order 18 db/octave, and so on. A logarithmic scale is used for the frequencies. An octave is the doubling (or halving) of the frequency. A 2nd order low pass crossover at 1000Hz will decrease the signal by 12db at 2000Hz, 24db at 4000Hz, 36db at 8000Hz... For reference, a 3db increase is twice as loud and requires twice as much amplifier power to create this increase. For people, however, a 3db change is the minimum noticeable change. It takes a 10db increase for a speaker to "sound" twice as loud. And this 10db increase requires over 8 times more power to create. 2x power for 3db, 4x power for 6db, 8x power for 9db, 16x power for 12db... What makes a crossover? The basic components of crossovers are inductors and capacitors. Inductors become more reactive (increasing AC resistance) as the frequency increases, and thus lower the sound pressure on the driver more and more as the frequency increase. Capacitors work just the opposite. They have higher AC resistance as the frequency decreases. Inductors, Capacitors, and Resistors are also used in other circuits like Notch Filters and Attenuation Circuits which can sometimes be included in the "crossover". Why build a crossover? It is a lot cheaper and easier to buy a stock crossover instead of building one, but remember that a generic crossover has not been specifically designed for your speaker drivers. Every speaker is different and the circuit required to achieve optimal performance cannot be found in a catalog. Stock crossovers also tend to use cheaper components like high resistance inductors that use thin wires. What is phase shift? Phase is the timing of a signal, and the shift is the degree of the delay that occurs on the signal when passed through a crossover. Each order of crossover introduces a 90 degree phase shift. A 180 degree shift is an inverse of the wave. If 2 speakers are 180 degrees out of phase then they will cancel each other wherever they produce the

Such a low frequency, a passive crossover would require huge inductors and capacitors. Even if the very best parts were auditioned and selected with care, such large circuit elements would incur unavoidable, substantial losses. To overcome this issue, we created an analog, active 2-way crossover, the Magico Analog Crossover or MXO. This substantial component provides steep filter slopes without any sacrifice in signal quality. The crossover’s meticulous design features Linkwitz-Riley filters to deliver 24 dB per octave slopes at the crossover frequency of 120 Hz. Designed in-house from our own platform, the analog crossover is fully balanced with completely discrete circuitry from input to output. Open architecture accommodates additional filter topologies. Precision step attenuators provide 0.5 dB/step control of each output, using a proprietary technique to ensure purity in the signal path. The external power supply chassis regenerates AC and applies active regulation to every part of the circuitry.

Same frequencies. Even with crossovers, both speakers will produce sound for several octaves beyond the crossover point. If this problem occurs, there will be a noticeable dip in the frequency response at the crossover point. To solve this problem, wire one, but not both, of the speakers backwards (+ to -). Usually, phase shift problems only occur with 2nd order (or 6th order) crossovers, but can also occur when using multiple 2-way crossovers in a 3-way (or more) speaker system. The only way to really find and fix a phase shift problem is trying all possibilities in reversing the speaker leads. If reversing the leads makes the system sound louder, then you know you have fixed the problem. What is inductive coupling? When using more than one inductor in a crossover, the electro-magnetic fields of the inductors can interfere with each other causing an unpleasant result. That is why it is best to keep the inductors as far apart as possible. Also, keep the fields out of phase with each other by rotating the inductors 90 degrees. It is possible to have 3 inductors out of phase, as shown below. Why do I need high quality crossover components? Both inductors and capacitors will have some resistance. Usually, it is small but sometimes it can be greater than the resistance of the speaker itself. Since the entire crossover network is based on the resistance of the speakers, this can be very bad. For an 8 ohm woofer with a low crossover point, the inductor in the low pass filter could be 16 ohms, or even higher. With a combined load of 24 ohms, the amp would not be putting out anywhere near as much power as it should. There are several ways around this problem. The first is to buy expensive components. What type of inductor should I buy? Inductors are usually just a coil of copper wire, sometimes hundreds of feet long. Copper is the only realistic material to use. One way to lower resistance is to use thicker wire. You can purchase a more expensive coil that uses a heavy gauge wire. Moving from 19g to 14g increases the price by at least 5x's. Using silver increases the cost another 20x's. There are also copper foil inductors which are more expensive, but work somewhat better. Some inductors have iron or ferrite cores in the middle of the coil. This core decreases the amount of copper wire needed for the coil, and therefore lowers the resistance. The problem is that these cores cause some distortion. For smaller inductors, use one without a core - an air core inductor. For the larger inductors required for the woofer's crossover, an air core inductor might not be feasible. In these cases, use a ferrite core. If you want to try to make your own inductor to save money, check out the Inductor Calculator for information on winding your own coils. What type of capacitor should I buy? For capacitors, a polar Electrolytic capacitor. Reverse engineer simple crossover to calculate crossover frequency . Reverse engineer simple crossover to calculate crossover frequency.

Home » ARTICLES » Why Would Your Car Audio Amplifier or DSP Need a Bandpass Crossover?When designing and integrating high-performance speakers into your car or truck, your local specialty car audio retailer might suggest choosing an amplifier or signal processor that includes a bandpass crossover. If you aren’t used to designing speaker systems, a task that most consumers don’t concern themselves with, then the term bandpass might be confusing. Please don’t fret; we’ll explain what it means and why it’s necessary to extract the best performance possible from your speaker upgrades.What Are Crossovers?The theory of a perfect speaker that produces the entire audio range, from a single driver, at an adequate output level with no directivity, is so far from reality that the concept alone makes a speaker engineer’s eye twitch. As such, we need to use speakers of different sizes to cover the audio spectrum. In the simplest of systems, we need a woofer to produce bass and midrange frequencies and a tweeter to produce high frequencies. Since most tweeters are rarely capable of reproducing information below 2 kHz with significant output, we need to block that information. We use what’s known as a high-pass crossover to pass only high-frequency information. Looked at another way, a high-pass filter blocks low-frequency information from going to your speaker.This graph shows the response curve of a high-pass filter set to a frequency of 3 kHz." data-medium-file=" data-large-file=" src=" alt="Bandpass Crossover" width="800" height="396" srcset=" 800w, 600w, 300w, 768w" sizes="(max-width: 800px) 100vw, 800px">This graph shows the response curve of a high-pass filter set to a frequency of 3 kHz.Once we have routed high-frequency information to our tweeter, we don’t need the woofer to reproduce those sounds. So, the technician configuring our audio system will apply a low-pass filter to the woofer at the same frequency. This filter passes low-frequency audio information below our crossover point to the woofer.This graph shows the response curve of a low-pass filter set to a frequency of 3 kHz." data-medium-file=" data-large-file=" src=" alt="Bandpass Crossover" width="800" height="396" srcset=" 800w, 600w, 300w, 768w" sizes="auto, (max-width: 800px) 100vw, 800px">This graph shows the response curve of a low-pass filter set to a frequency of 3 kHz.What Is an Electronic Bandpass Filter?If we decide that we want to further upgrade the audio system with a subwoofer, we’ll need more filtering. Subwoofers are great at reproducing audio frequencies below about 80 Hz. Most don’t do a good job with midbass and midrange information. As such, we want to block frequencies above about 80 Hz from going to the sub. We’ll use an 80 Hz low-pass filter to accomplish this task.This graph shows the response of a low-pass filter set to a frequency of 80 Hz."

Sound intact. Notably, the RMS level sensor also adds to the natural feel of dynamic processing of our compressors.For a detailed technical article on side-chain filtering, including frequency response plots for both Feed Forward and Feed-Back compression modes, see the following post:CrossoverThe CompIQ Twain features a variable-range Linkwitz-Riley crossover (70Hz to 1KHz), which splits the input signal into two separate frequency bands processed by dual compression engines. The crossover output also feeds the Dry Line, allowing seamless blending of Dry and Wet signals without phase cancellations, no matter where the crossover is set.To illustrate, a chart shows matched levels of internal and external circuits with the crossover at 1KHz, output set to buffer level, and Mix at 100% Wet. The chart demonstrates nearly perfect alignment of phase across the audio spectrum.The input signal’s phase remains a straight line, but the output signal’s phase gradually shifts from 0° at the lows to 400° at the highs. This is a normal result of the signal separation and recombination by the crossover’s band filters and compression engines.The following drawing illustrates the Crossover Knob Frequency Scale for Twain MK1 and the most suitable setting for utilizing the Saturation feature.CompIQ Twain Crossover Frequencies & Best Saturation RangeFor a detailed technical article on Twain MK2 frequency response, see the following post:Tape Saturation Lo & Hi-Cut filtersBoth the CompIQ Stella and CompIQ Twain MK1 compressors offer an analog Tape Saturation circuit that exclusively affects the Dry signal. This lets you add optional saturation to your signal, which can then be blended with the compressed Wet signal to introduce harmonic distortion and warm up the audio while preserving the compressed signal’s dynamics. Note that you might need to dial in some saturation before it becomes audible due to the high headroom of the saturation circuit.For the CompIQ Stella, you can activate the LPF and HPF by removing the internal jumpers. The CompIQ Twain has variable filters accessible through small trim knobs. The HPF is for the Lows band, and the LPF is for the High band. In both compressors, the HPF is placed before the Saturation engine, while. Reverse engineer simple crossover to calculate crossover frequency .

Calculating crossover frequency the other way around?

Passive crossover, a source of audible distortion of your sound, with a precise Active Crossover placed ahead of your power amps. The power amplifiers drive the woofer and tweeter directly with no passive components getting in the way. The result is nothing short of breathtaking. You’ll hear detail and color in your music you’ve never heard before. The sound stage opens wide in all dimensions, and you can picture every instrument as if it was in the room with you.One of the most important specs for an active crossover is phase coherence. This is the alignment in time of the high and low outputs. If these are out of phase, sounds that are at or near the crossover frequency will be significantly distorted, because both the woofer and tweeter are both driving at this frequency, and if the channels are out of phase they will each be creating slightly different sound, which creates distortion. This video shows how precisely our channel phases are aligned:
