In this video I tell you a bit more about crossovers and the components that make them up, as well as showing you how to mount the components on a board and how to solder the components together.

This might be the best and most detailed video I’ve seen demonstrating the process of building a crossover. And yes, I would love a very detailed video about how these components work and how you determine what to use for any particular driver.

Thank you so much. This was very clear and easy to understand. The polarity and magnetic field information were critical to my newbie learning, very complete. All of your videos are top notch! I cant wait to get all of my parts for the slimline stand mounts to get started! I have a feeling that I will be building many more of your projects. Anxious to hear how the Arylic center project turns out. Thank you again!

Always appreciate the time and effort you put into your videos. This one was informative. I’ve see you touch on crossover design in several of your builds, but it would be great to see you break down the crossover design process with some descriptions of each component’s purpose beforehand. Awesome job, pls keep em coming!

Good guide. I was just wondering how to create my crossover - overthinking everything as always. KISS is the motif of the day.

@davidjudd951 9 ай бұрын

As a young technician fresh out of electronics school, it took several service calls with an old pro, for me to understand the KISS rule. Now as a 40 year veteran in the industry, I remind myself of that rule regularly.,

Very professional, helpful and detailed video and I'm using it as a guide for my own little 2-way, 2nd order Xover; though it appears that the hook up illustrated on the ground side of C2 is not in accordance with the schematic.

Please do a xo tutorial especially using resistors how values of passive components relate to the freq you cross at? Like does it depend on anything? Like eg does 4.5mH inductor will always cross at same freq irrespective of driver used? Etc

It would be good to point out that resistors to be used must be of higher wattage rating than used, for example, in more common PCB circuits videos. (Despite the visuals provided.)

My JBL 120ti 3-way crossovers used .01uf 200V DC bypass capacitors with the capacitors (36uf 8uf and 14uf). Is this an advantage or can they be replaced or removed when upgrading to Dayton poly capacitors?

@JohnSmith-kn5wt Жыл бұрын

That was a fairly informative video however always using high speed to show what you are doing only helps shorten the video length. Showing real time in the beginning doing the soldering to get a good foundation is essential to learning. Once the concepts are understood, then things can be accelerated. The best way to watch you build the crossover board is set playback to .25.

I have a question on a bandpass crossover to my midrange. The midrange is a 8" RadioShack mid. I currently have it connected to a simple 20uF Polycap 1st order crossover. All speakers 8 ohm. The woofer 12" 50hz11000Hz full range RadioShack ( no crossover) the tweeter replaced (was RadioShack horn)with Morel Cat 378. This became the issue so I went with a second order crossover by Dayton audio 2000Hz 5uf Cap Dayton with 2.27mH inductor. Better now but I attempted several tries with Polycap and resistors with the final decision of the Parts Express. Sooooo now with nice Polycaps left over I thought I would try to do a bandpass ...just to try. Unfortunately the only info I have on the midrange is 8 ohm 8" Fs 100Hz. The speakers sound good but more sensative to poor quality recordings of cd's or albums. any thoughts Thank you for the videos

@PhillioDoede Жыл бұрын

Good video but its missing the same thing I see in most crossover beginner guides which is the relationship between the logical diagram and physical network connections. Your plans show how to physically build it which is great and you can reverse engineer the physical plans in relation to the electrical / logical plans but I think this video could have been a good opportunity to explain that better so when a user sees the electrical diagram it intuitively makes sense.

is ok to replace 10W 2RJ resistor with 10W 2.2ohm resistor in speaker crossover, will it be any big difference

@SoundBlab Жыл бұрын

It really depends where that resistor sits in the crossover schematic, but generally resistors have a 5% tolerance in actual value, so it should in practice not make a huge audible difference.

@SoundBlab Жыл бұрын

I don't know what the RJ stands for, but it is still just a 2 Ohm resistor, most likely a typical wire-wound in square cement or ceramic casing.

Where's the best place inside the speaker box, to mount a crossover? Im replacing the crossover in a traditional 22 year old box floor speaker. The new crossover is much larger than the older crossover being replaced.

@SoundBlab 8 ай бұрын

This will depend on how you have access to the inside of the enclosure. This will normally only be through a woofer opening, so mount it on the back panel if you can or in the rear corner on the bottom panel, but make sure it is at least a few inches away from the woofer motor structure (magnet). If the board is too big for the opening, try making the crossover on two smaller boards, splitting the low and high pass sections.

Just once I would like to see a crossover video that slows down and explains which are positive and negative. The is unstable but they twist a big rat nest of wires together it just looks like a big mess of confusion the reason why I watch these is because I don't know what goes where. I don't get it. My crossover would be huge because I connect everything separately. Just slow down and explain it

@kennmossman8701 Жыл бұрын

no.No.NO!!! do NOT solder wire/cable directly to the leads of components - at least anchor the wire to the board. This will either break the lead or damage the component.

@SoundBlab Жыл бұрын

My experience tells me different. I have done exactly this a million times without any issues as you mention. Internal wire is normally kept in place by cabinet damping material or even secured to bracing with a cable tie or two, so we do not have it moving in the cabinet that might cause continued and excessive back and forth movement that can snap a component lead. But if this is a worry for anyone, then feel free to anchor the wire in some way.

@kennmossman8701 Жыл бұрын

you do not test before soldering to the speakers??? not even a polarity test?

@SoundBlab Жыл бұрын

There is no effective way of testing a crossover without the proper equipment that can do a FRA analysis, and is normally outside the scope of the average builder. Thats why it is important to double check all the connections.

@kennmossman8701 Жыл бұрын

@@SoundBlab I would do; 1 -a test for obvious short 2 - a polarity test 3 - basic test; is the sound coming out from both speakers as one would expect Further , given the wide tolerance on these components I would test first - there are apps that can do a frequency sweep or generate a tone at a specific frequency. It isn't as good as doing a 'FRA' but would give more assurance.
