    For a year ive built 6 boxes and spent alot of money to get nowhere. Most of them are a shelf or bench now. I have tried to figure out winisd for hours. Up till 4am and got nowhere. I watched about every video on you tube that had anything to do with it and they didnt help. Crazy i know. Dummy right. Well i dont know why its so hard for me. I am usally very good at everything i do. I know because that is what ppl tell me. Anyway this video is by far the best ive seen. He explains everything and shows you exactly what to do. I cant tell you how happy i am to have come across this and i will talk about and recommend it all the time to everyone. Thank you so much. Cant wait to build a box and see how it sounds😬😁😎😬

    Great video, very encouraging. I spent a few hours trying to calculate qb3 box size using the Dickason cookbook 3rd edition. I worked through one of the examples okay. Taking an actual driver, using Qts to select alpha, f3 ratio and H to calculate Vb and Lv, I got numbers that weren’t close to the parts express box volume. In fact, Qts was .57, just past the range on the table! Thanks for the video and putting the calculator out there. I’m hoping to put together a 8-12” subwoofer and this is a great help.

    Hi thanks alot on the video. Currently I am try to do an enclosure for a audio pulse revo 15 for home theater use. So size of enclosure isn't an issue. The qts on the driver is 0.44. The recommended enclosure from the manufacturer is seal of 4th order but I want to do an areo port enclosure. What are your thoughts

    • @AudioJudgement
      @AudioJudgement  2 ปีที่แล้ว +1

      I would do a bass reflex enclosure. 180 liters (volume displaced by braces, port and speaker not included) and port tuned to 20 Hz. If you go for a 6" diameter port, it needs to be 64 cm in length. Problem is that you might run into port noise at very high volumes. 500W you are in the clear. At 1000W you will hear some chuffing. If you make the port larger in diameter, the length requirements become unreasonable. So, either use a 6" aero port and keep it down, or consider a larger slot port. If not, a sealed 80 liter box will also do (not as much low end, though, which is desirable for home theater)

      Here is a case scenario : If you need 60 liters and let's say port plus speaker occupy 5 liters, if you make a 60 liter box then your effective enclosure volume will be 55 liters. In that case you need to make the box volume 65 liters.

    Hello. I have a question about the volume the port takes up.

How do I know what the box volume will be before I design the port volume if one value changes the other?

      @DodgyBrothersEngineering 2 ปีที่แล้ว

      lol you have to chase the dragon (no I don't mean taking drugs) but every time the box volume changes it is going to alter the port length which in turn alters the volume. Don't know how to properly describe it, but you kind of need to guess ahead of what you need.

      it's says N/A because you have a high Qts speaker (Qts > 0.7). In that case you set the volume and box tuning frequency however you see fit, as alignments are not available for your speaker.

  • @audfrknaveen2256
    @audfrknaveen2256 3 ปีที่แล้ว

    In a rectangular slot port, the box walls are acting as port walls too, and they extend longer than port. So some people say WINISD shows upto 30% longer port length than needed. How far this is real ?? Any suggestions on this please ???

    • @AudioJudgement
      @AudioJudgement  3 ปีที่แล้ว +1

      WinISD shows the correct length. Indeed the formula for calculating port length has a correction factor which is different depending on the type of the port / flare etc (length calculation might differ from app to app). But that only accounts for a very small percentage difference (not 30%). The fact that a slot port is extended by the walls only happens when the port end is near the box corner.

      @AudioJudgement  3 ปีที่แล้ว +2

      I'm not familiar with bassbox pro, and I'm not sure what you're doing. A dual voice coil woofer basically works the same way as a single coil subwoofer. Only difference is that you can wire the voice coils in series or parallel. Regardless how you wire them, Fs, Qts and Vas won't change their values, so there shouldn't be any differences between the excel spreadsheet and bassbox. However, if bassbox thinks that you have 2 voice coils and you connecting just one, and leaving the other one disconnected, then yes, the response should be different. But you are probably not going to do that.

    • @AudioJudgement
      @AudioJudgement  3 ปีที่แล้ว

      Positioning inside the room is very important. E neat trick to find the best position is to place the subwoofer in your listening position (on the couch for example). Play some bassy music. Then walk around the room and listen to how it sounds in different spots around the room. In the spot where you find it most pleasing, that is where you should place the subwoofer. Alternatively, if you already decided on the position, and don't want to move it, you can try and reverse the polarity of the speaker wires. It might sound better, but no guarantee.

    2 ports are better than 1? Please send me

      Usually they are, but they need to be quite long. If the length requirements are not too bad it's better to have 2 rather than 1.

    Typed in FS: 34Hz. qTS: 0,59. Vas:63.3L Box volume of 105l and tuning of 34 on the ported box. But nothing happens. I also see that the tabs on the bottom left has locks on them

      You need to enter Ql as well. Usually Ql = 7 for normal box losses. The spreadsheet is protected so you don't mess up cells with formulas. You can remove the protection if you want. The password is just a blank.

    That was quite heavy watching (you covered quite a lot) but one thing you didn't touch on was the disadvantages of using a rectangle port. BTW why can't you work out port velocity?

    One little thing, didn't allow for the port wall thickness of the 100mm round port :)

    • @AudioJudgement
      @AudioJudgement  3 ปีที่แล้ว +1

      You are right, I didn't account for that. But usually that is 3 mm plastic and in most cases that adds up to negligible volume displacement.

    • @st170ish
      @st170ish 3 ปีที่แล้ว

      @@AudioJudgement yes the amount of volume in this case is negligible, but in a small volume enclosure with huge ports this probably would cause a deviation to the "planned" response.
      I've always planned 3 enclosures, one the wanted volume and one a bit smaller the other a bit bigger, this give us an idea of how much inaccuracy we can tolerate before adversely effecting the desired tuning.(be great subject for a future video!)

    Toti vorbiti despre cum sa proiectezi o cutie noua. Nici unul nu vorbeste despre: ai cutia, ai difuzoarele, ce poti sa faci sa le combini ca sa sune bine.
