Good video. The phases of the drivers don't neccessarily need to align as you can use filter Qs other than .5 (Linkwitz or -6db) such as .71 (Butterworth/ -3db) and also filter orders other than 2nd, and you might be able to make it work that way.
From this video I know: passive = amp -> filter -> transducers active = filter (DSP) -> amps -> transducers So the next question may be: what are the pros and cons of passive v.s. active crossover design? Thank you for this consise tutorial.
Thanks for watching, Owl Mega! This is a great question. I’ll try to make a video on it in the future, but here’s a quick answer for you. Forgive me if it’s an incomplete answer (I’ll need to do more research for the full video on this subject!) Passive crossovers are more simple (and often cheaper) to set up for the consumer/system tech, while active crossovers require a DSP or DSP in the amp. This means you’ve got a lot more flexibility and ability to fine-tune with an active crossover. DSPs will also have additional settings like delay and EQ which make them even more powerful for system tuning and alignment.
Generally there isn't an inherent SQ benefit to any of those concepts. But when dealing with very low cut-off frequencies or very high power, active (can be analog as well) is the way to go. For a regular 2- or three way speakers passive is the more sensible choice as it enables you to use any amp you want.
@@westelaudio943 Hey, that makes a lot of sense! For excessive energy it's beneficial to filter first and then amplify (thus active). Thank you for explaining. While passive is cheaper (needing only one amplifier) and more suitable for consumer devices.
Been here since the beginning. Back after a while. So glad to see this channel grow. I'm glad there's someone explaining the fundamentals so well in a field full of snake oil. Beginners will benefit a lot from your channel. And even professionals can pick up important points. Great work!

Hello, I love your channel I've been binging your content for weeks now, thanks for all the clear and concise info. Could you consider making a video on speaker enclosure design, enclosed, vs front ported vs back ported in different room sizes? It's been difficult for me to find info on the subject.
Hi, Henba Irom! Check out this video: ua-cam.com/video/o2uJst2aObI/v-deo.html For tips on acoustic treatment, check out the GIK Acoustics UA-cam channel! They’ve got some great info over there.
Not that acoustic treatment is soundproofing or anything, but by placing a gik absorber/diffuser panel on my back wall, I get the same loudness satisfaction with my music/movies listening but with lesser volumes. 😯 Perfect if one got neighbours to consider!
Super intro to crossovers, thank you! One comment... [EDITED further down] Coming from the computer world, I'd rather talk about "Crossover circuitry", than "crossover networks" ;^).. Indeed, the term "crossover" already contains that idea of directing "stuff" to the right place, in our case that "stuff" being analog (or digital) electrical signals: adding the attribute "network" would be a pleonasm... If not misleading: in a network, nodes communicate between each others, while in a crossover circuitry, those "nodes" elctronic elements essentially act upon an input, having quite different functionalities (except may when there's a row of capacitors, resistances or whatnot), without any restriction when it presents itself at the gate of such element in order to provide an "output", and don't care about anything else including other "nodes". IMHO, It'd rather be some _kind of a switching device_ than a "network"... *EDIT:* after some thoughts (I'm new to the Audio technical World)... I understand why you speak of crossover "network", especially in "hybrid" mode, when there are more than one crossover devices in the sound system and which are acting on the response of a previous crossover device. e.g. using an active crossover before the amplification, along passive crossover devices (or "crossover nodes") that would be present in one or more speaker cabinets so as to "switch" from a driver to another, depending on a predetermined frequency band (which is thus acting like a specific "driver address", in a network of speaker drivers where each crossover behaves similarly to a network switcher).
Have you thought about making speaker reviews or in depth speaker breakdowns and set ups on another channel? (Not sure if it would fit on Audio University channel is all)
Thanks for the suggestion, Freg. I’ve considered doing more reviews. What would you describe as an ideal speaker review video? What tests would you like to see?
@@AudioUniversity Maybe a review of the speaker response in-depth - this is something you've covered in the past but I think doing it on individual systems where you can find that information might be useful especially to someone who doesn't fully understand frequency attenuation and accentuation. A basic review of quality (Everyone does this already I feel like, and its also pretty subjective*, but eh if its particularly bad or good its something talk about) I think that there's alot of sort of "Buy the brand, not the product" stigma with sound systems so having access to information like this, that's formatted so well like ur videos would be beneficial for uninformed or new buyers Another idea would be to offer how you would configure that speaker ( this might not be as useful thought because obvs everyone is going to have different amps and be producing signals from different sources but its still an idea) All ideas, long time fan and always eager for more! *It can be subjective, talking about audio quality of top systems usually leads to conversation that goes round in circles and boils down to taste or biases.
I have 2 3-way component speakers (Audison APK 163) for the front and back. I also have a Audison APBX 10 AS2 Prima Subwoofer. What is the best amplifier for this set-up of 12 total speakers and a subwoofer?
I my church we only have a 100w amp for indoor units and the speakers are 100w+100w(peak) and have 16 ohm connections. Is there any way to reduce the power consumption of the speakers.we are ready to sacrifice sound quality or volume level.
you can also make an active crossover with operational amplifiers and passive components. which is really the best way to do it if your not processing the signal. can be integrated within the amplifier. you can make a state variable filter that gives you high low and bandpass (middle) frequencies all in one filter. active filter design in analog is complicated there is a lot of stuff. you do that before the signal is amplified not before because op amps dont really provide much current to drive speakers. so you do it at line level signal. id bet some old school gear did it that way. I use op amp for my audio projects a lot
Hi, this might be a silly question but basically I have a sound system that works like this: PC Sound to 3 channel mixer, Mixer output to powered sub line in, powered sub line out to a Bluetooth amplifier which feeds my main aiwa hifi speakers. The crossover that is set to 90hz on my sub doesn't appear to work. I can still hear frequencies below 60hz on my speakers. Do you have any solutions for this problem?
Slope is the “angle” of the drop off frequencies. A 6db slope the drop off line will be very gradual. An 18db slope that drop off line will be very sharp and closer to straight up and down If that makes any sense
Question please. Do main outputs and mon (monitor) output are totally separate lines. My problem is because I get alot of high frequency loss from my floor monitors when the bass is playing . We loose guitar high and some meds frequency. I do have crossover from my subwoofer to my top speakers but there is no low cut or frequency cut setting in the mon output and so my monitors speakers don't have any settings for it
I already know much of what you go over in these explanation videos, but I watch every one of them because of how good at laying it all out you are.

Could an active crossover be helpful in a tube head that guitarists use to power a 4x12" cabinet? Does anyone know? Or do you not need one?

To build a proper speaker crossover you need a lot of knowledge and about 20 years of expirience + equipment.

How do you calculate what slope and at what frequency to crossover in order to find the -6db transition

hi sir can I use 8 ohm tweeters with my speakers is 6 ohm
you can also make an active crossover with operational amplifiers and passive components. which is really the best way to do it if your not processing the signal. can be integrated within the amplifier. you can make a state variable filter that gives you high low and bandpass (middle) frequencies all in one filter. active filter design in analog is complicated there is a lot of stuff. you do that before the signal is amplified not before because op amps dont really provide much current to drive speakers. so you do it at line level signal. id bet some old school gear did it that way.

With how easy it is today to program a dsp, i think that active analog crossovers are essentially dead today.
Hi sir, a small doubt I have Klipsch RC 52 crossover, it is used to rc 62 speaker drivers

Type shit
lo tuyo es increíble, unos subtitulos ayudarían mucho
Does anyone know what's a slope?
Slope is the “angle” of the drop off frequencies. A 6db slope the drop off line will be very gradual. An 18db slope that drop off line will be very sharp and closer to straight up and down
If that makes any sense
It how fast your speaker rolls off
Can you add subtitle?
Shouldn't it be a straight line?
You have two dips where they intersect
They will sum together to fill in that space and make a straight line, ideally.
