@@mnfaditya2166 I know its a real old comment, but for anyone seeing this video with the same question (or if you're still wondering). Some kind of Thiele Small parameter test device like the DATS system by Dayton should do the job to get you the numbers you need. Dd is always measured as the diameter of the cone including 1/3 of the surround on each side

[@RadiusNightly]

For closed and ported box i found Box-Port Design 2.2 much simpler, faster and easier, specially for active 3D box design as you are changing variables. Later on you can move all this information to another software for future tuning with more variables.

Their port is too small and you probably don't have a high pass on

@@Toid Thank you very much for your reply. I'm trying to build a box for a Dayton RSS315HFA­8 12" Reference HF Subwoofer 8 Ohm, with the box tuned to 20Hz (4 cubic feet). In the System Input Power field I entered 400(w). I used the HP filter option (20Hz) to get rid of the dangerous cone excursion, but the rear port air velocity is off the chart...literally. Do you have any suggestions? Thank you for your time.

[@Toid]

@@richardt2353 my friend and I used the 15-in ho version of that subwoofer and you can see the box that we built here: kzbin.info/www/bejne/g3-4gZWnrsSDmq8 we ended up using three long slot ports to get Port velocity down. Maybe that'll help you with your.

@@Toid I think I made a mistake getting this subwoofer. There seems to be no way to alleviate the outrageous post velocity numbers by tinkering with the port(s). Would I be better off making a sealed cabinet for this sub?

[@fishrsa9046]

oof, my sub(a $100 japanese nakamichi sub) has a really badly written manual. some of the specs(Mms) are missing and some of them don't seem to make any sense? my Sd says "50.2m M" lmao what does that unit even mean, and my Cms says "176M/N" which doesn't seem to be a real number considering it looks 1,760,000 times bigger than the number yours gave

[@WickedMoto]

What if the sub you are looking at doesn't have SD? specifically the one i'm looking at is the car audio, sundown audio sa-15. very minimal specs

[@Toid]

I am not sure which version you are talking about, but I used this version: www.amazon.com/SA-15-D2-Sundown-Audio-Subwoofer/dp/B00EVYTAMU Enter in all your known values and it should auto calculate SD - it did for me. Just input all you MMS, CMS, BL, LE and everything else you know at the bottom. Then go up to the top and enter the numbers 1 at a time until it auto calculates everything else. It should work perfectly. It autocalculated an SD of 337.7 cm squared. I would not input that, let winISD auto calculate it or you could fail driver integrity check.

[@WickedMoto]

Ok, sweet. Thank you. I got the specs off the main sundownaudio website. I just input it all and saw that it did calculate it for me, thank you very much for the help!

[@WickedMoto]

+123Toid I must have done something wrong, I'm using the dvc dual 4 ohm model. It calculated SD to be 792 cm Squared? That doesn't sound right

[@WickedMoto]

Also +123Toid do I put Znom so what the sub is specified as "DVC 4 ohms", so coils I would set it to 2 and then Znom would be 4, and connectivity would be parallel since i'm going to wire each sub parallel for a final 1 ohm impedance at the amp?

[@user-ui5ze8br8x]

i usually email the manufacturer, you can also call and they will hook you up with a spec sheet... good luck my fellow base head ;)

[@kft590]

Isn't the created Speaker data somewhat useless since it creates a perfect flat linear graph, it seems unlikely that it is representative of what the graph should really be.

[@benduffy4223]

Its linear like that because the box, vent/port, and signal data has not been entered yet. The curve starts out basically with a ridiculous sized box at 1W

[@mattwilderx85]

What if when entering the custom driver parameters the auto calculated numbers don't match the listed parameters from the manufacturer? This happened to me on the Dayton PS95-8. Just makes me worry that I'm not getting accurate data for that speaker.

[@Toid]

As long as you put them in the order I showed, the numbers will come up very close to the published specs on Dayton. This is due to WInISD using algorithms to figure out data. If you tried to fill them in with Daytons spes, it actually would not work. This is one of the things people worry about, but with how close they are, they will not affect the projections. So don't worry, you will be getting accurate data.

[@mattwilderx85]

The other areas I'm spacing on are what volume and frequency to use for the box, and i think my curve on the Transfer Function Magnitude is off. it ramps up to 1.843dB/68.36Hz, then falls to -0.073dB/92.36Hz, then back up to 1.162dB/178.19Hz. Everything I've seen seems to imply that the arc should be consistent, and then flat line as much as possible, but mine is wavy. I think I've done something wrong.

[@Toid]

You haven't done anything wrong. That is exactly what I get when i input that driver, using a ported arrangement. This is just how this speaker responds. If you look at my ported video, it shows a similar (not as bad as the Dayton PS95-8) response. This really is due to the speaker. You get a much flatter response going sealed, but won't get anywhere near the low end range. But just to make you feel better, the way the Dayton PS95-8 is not abnormal for a speaker. There are many that respond this way. On a final note you could try a 0.135 cubic foot box with a tuning of 80hz *which makes the curve flatter). This will make everything from 80hz to about 200hz have a +2db increase. In other words, you will get a little more out of the bass region. Just remember WinISD will give you what it thinks is the best response, you can always mess with the cubic feet and the tuning frequency to get teh response you want

[@mattwilderx85]

Say you've gotten you're desired response but it doesn't work with your box design. Can you have a box chambered with in a box? Also, is there a rule of thumb with finding smaller full range drivers that react better than the PS95-8? Thanks for the advice, I'm trying to learn all I can.

[@Toid]

I'm not sure what you mean. Can you be more specific about the chambered box within a box? As far as the second part of the question, I'd say a lot of people like the Dayton ND90-8 speakers. Most people use them in something like Paul Carmody's Sprite build. My next build will be using these speakers along with a passive radiator (making the box smaller). I plan to show the plans in my next video, which should come in the next few days.

[@arunshan3399]

What if I wanna add more than 1 sub? I am trying to figure out a box for 4 DC Audio XL 10"

[@Toid]

Well that depends. You can put four separate enclosures right next to each other or when you go through when is d and select the number of drivers, just put four instead of one

[@wedastars]

I am using NVX VCW124 and they dont have MMs Listed anywhere...:(

[@Toid]

If it doesn't have mms, just input all the data it does have and mms should auto calculate. Be careful putting in your q values. Put them in one at a time as some will auto calculate for you. If you put them all in, you may receive an error.

[@rasmussundstrom2433]

I'm trying to calculate a box for some bookshelf speakers I'm building, using the Dayton nd140 8 ohm drivers but for some reason whenever i enter Mms and Cms it auto calculates Fs to 1.88 hz wich is obviously not correct, and if I correct it to what Dayton audio says(59.2hz) I try to save the driver file but the error pops up. If i don't correct the Fs, the driver saves without any issues only with an fs of 1.88 what could be the cause of this and what can I do to fix it?

[@Toid]

It sounds like you have either you MMS on Kg instead of grams or your CMS is not on mm/N in the program. Just click on the Kg to change it to grams and input your new value and same for CMS. I did just input both CMS and MMS in WInISD and it derived 56.61hz.

[@edrickmendez7978]

123Toid when you put the box dimension of cuft. its the internal box dimension (Net Volume) or its the (Gross Volume) Outside of box?

[@Toid]

Great question. This is internal box volume. The gross volume will be dependent on the size of the material and the amount of bracing you use.

[@itekani]

So what is really the secret to not getting an error after inputting the parameters?

[@Toid]

The video explains it

[@itekani]

@@Toid I watched, but I don't really see what why it works. Is it the magic order in which the parameters are entered? If this is the case, how do you know the order?

[@Toid]

@@itekani it has to do with how it auto calculates the values. Unless you put them in any order as long as you delete, some of the values the computer wants to auto calculating you put in.

[@itekani]

Terrible UX design... 😄

[@Chrick]

The voicecoils parralell?? They should be in series...

[@audiokees4045]

I did try do not work, also the driver comes on not in the list. strange behavior.

[@johnviera3884]

Sd is the SIZE diameter of the cone area. Sometimes it’s not listed. Use Google For example: a 12 inch woofers cone area is approximately 11 inches across. 11 diameter inches = 121 square inches. Make sure the little thing next the Sd box says “sq in.” Enter 121 in the Sd box Without an Sd parameter you can’t get accurate graphs. For example: cone excursion. This dude spent 10 seconds on Sd.

[@iterminator309]

Sd is the Surface of driver.
