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😬😁😎😬
OMG... The spreadsheet helped me narrow down from about 12 drivers to 3 in 30 minutes!!! Using WinISD woulda took me an entire afternoon!!! Thanks you so much
Fantastic video!!! Thank you !!!! I have watched dozens of videos; yours actually explains things to the perfect level. The spreadsheet is awesome too !!!
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.
Was searching for 4th order single reflex band, came across your video, gonna be tricky with the port area not knowing the air velocity, all depends on power to the sub, xmax and box size, I have no experience in designing but I'm willing to learn, subbed, very informative and I will be downloading the spreadsheet will be very useful using the sub qts to determine the appropriate values for the box, thanks for the spreadsheet bro.
thanks for the info. Im still a bit confused by how to make make a box with a specific tuning frequency Fb. and in the video it is a bit confusing when you mention the type of the box without showing an example of what it is. i guess i'll have to rewatch it. do you have a video about Fb of boxes? I'll check out your courses soon, if they are as good as these vids im sure it will be worth it. thank you.
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
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)
@@AudioJudgement Hi thanks alot. Continue to share knowledge. I am trying to understand the bass alignment examples. Are all the alignment normal ported enclosure?...when I saw 4th order is that band pass? Sorry now learning about enclosures and live in the Caribbean. Was planning to use 3 ...3" or dual 4" precision areo ports to eliminate cuffing. Really appreciate your help. Thanks again
Great video and explanation. But one question: In your example, port an speaker volume add volume to the 60 liters box, obtaining 64,85Lit. It is ok? Or shold they substarct to the 60 liter volume of the box? Obteaining arround 55,15lit efective volume ? Sorry for my confussio. Thank you for your explanation and great videos.
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.
@@AudioJudgement Understud! Thankyou!. I use your video to re arrange a "store car subwoofer" into a Fj Cruiser, I calculate and print a 44 mm wide 71 mm long tube that I fix into tje new box. It works like magic! Great and solid bass. Thank you again!
Hello Marius thank you for the videos they are very informative... here im facing some issue with excel spreadsheet the thing is even after entering all the speaker why bass reflex alignment still showing N/A..?
Hello. I have a question about the volume the port takes up. If I subtract the volume taken by the port from my internal cabinet volume, the spreadsheet then tells me that the ports need to be a different length. How do I know what the box volume will be before I design the port volume if one value changes the other?
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.
How do you handle a mystery driver where you can't find TS parameters nor measure them yourself? I have a salvaged Klipsch 12" woofer and I can't find the spec sheet for the driver itself anywhere.
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.
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 ???
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 thanks a lot for the response !!! 😊 I was refering to the topic in the link below ...(looks like youtube is not allowing to paste a link in comments)
Speaker Qts is larger than 0.7. No alignments are available for that speaker. You just have to use a box volume and tuning of how you see fit (just judge the frequency response)
Hey Marius, brilliant videos! I have a question: do you have to manually subtract the volume of the port? I always assumed the software takes care of that. Cheers!
Hello! You have to subtract it manually. You can always place the port outside the box (it will look weird but you can do that), and you don't need to subtract it in that case.
Hey Marius, great videos. I am building an enclosure for 4 x 4" speakers, firstly I think it would be a sealed box not ported, how would I input the data into the spreadsheet or is it just the same volume multiplied x 4?
If you change the END CORRECTION value, is Winisd showing any change in vent length or tuning ??? For me nothing is changing, whether I use 0.732 or 2.227 as end correction.
@@AudioJudgement that's a problem !!! Building a sub with wrong port length is a tragedy !! 😀 Ofcourse I'm talking about slot port. Il try to contact the WINISD makers. 👍
@@AudioJudgement by the way is it possible to share your email id or whatsapp number Marius ?? I want to share some private info. Not about winisd though....
@@AudioJudgement no at all, I’m using a pc. Bought some cheap lanzar 15” with hardly any ts parameters listed and currently trying to find out what can I do with it. I’m just experimenting with diy builds, not sure if it’s worth it but for now it’s fun.
If you have multiple folds, just consider the total length as if the port is straight. If your port is more complex, like tapering, you need to model in hornresp or some dedicated software.
I have a question..I've downloaded the excel sheet and been playing around with it..and correct me if I'm wrong but this is more geared to single coil woofers?....what happens when I use a dual voice coil woofer...I ask this because I also use bassbox pro and when I enter these parameters...I pretty much get the same results as ur excel file...but when I indicate is as a dual coil woofer, it changes completely.
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 OK thanks for the reply...love the videos....I would love to see some more content on bandpass enclosures...in particular 6th order series tuned...if you have any content on them...either way keep the videos up🤟
@@vilmuss149 i suspect that Bass Box Pro is assuming the parameters for one coil also applies to the other coil. so if it says the sub is 4ohm 500w, it assumes each coil is 4 ohm 500w. so if u try halving the numbers when u select dual coil, it mayyyyy give closer to the real result.
Sir, I am facing two problems. I made an 8 inch sub woofer ported box, the sound is good beside and behind the box but not in front. The bass is very bad in the middle of the room and is good near to the walls. What should I do. Should I use the horn shape design for the sub woofer.
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.
@@AudioJudgement Thank you for your explanation. But there are many other questions in my mind. In the Sony party speaker MHC-V42D the JET BASS BOOSTER TECHNOLOGY is used for long distance bass.They use the tapered bass reflex duct to achieve it. Please explain how to deliver bass over a longer distance and how a tapered duct helps to enhance the bass pressure.
@@yuvrajsingh2696 while tapering the port will have some effect. That jet bass mumbo jumbo is just pure marketing. If you swap those ports for straight ports, I guarantee you won’t notice any difference.
Awesome, awesome, awesome. Wish I had watched this earlier. I would have gone for ported. As the driver i was getting in India only gave 4-5 parameters and winisd just refused to give any output with such limited data, so I told my carpenter to make sealed (because that would hopefully be dumb people {me} proof) Had I watched this earlier I would've gone for ported which I originally wanted. I'm using an 8inch driver for a sub to be added to my desk setup (near field) hoping it works. Any recommendations on type and amount of damping material (30Ltr box)
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.

@@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!)

@@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!)
