    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!

      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.,

    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

    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?

    Is the mH value of an inductor determined by the thickness of the coil? Or according to the circumference?
    For example, a 6mH coil comes in thicker thickness. It also comes in less thickness. What is the difference between these two? What should we choose? There is no problem if the millimeter size is changed?
    Please reply sir

    • @SoundBlab
      @SoundBlab  3 месяца назад +1

      Typically the thicker the gauge wire used for similar value coils, the less resistance it has. Thus you can use thicker gauge coils for lower frequencies so that we do not lose SPL in that lower frequency range due to higher resistance of thinner gauge wire.

    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

    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
      @SoundBlab  Год назад

      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.

    • @davidjudd951

      I put it on the bottom.
      Clamp glued 3/4" solid wood cut to the size of the crossover, to the bottom of the speaker, then mounted the crossover to it with non magnetic screws.

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

    • @SoundBlab
      @SoundBlab  Год назад

      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.

      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.

    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.

  • @JohnSmith-kn5wt
    @JohnSmith-kn5wt Год назад

    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.

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

    • @SoundBlab
      @SoundBlab  Год назад +1

      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
      @kennmossman8701 Год назад

      @@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.

    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
    @kennmossman8701 Год назад +2

    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
      @SoundBlab  Год назад +1

      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.
