Some musing about the future of the service(Too much text but should read if you like the service): I've been developing the service for about 3 years, I've done many features: we have 3 clients(iOS, Android, WEB) and backend to connect it all. The project

After the changes in the website 3D and drawing just don't work. I have deleted the cookies and the user data of the webpage but still it doesn't work. I really hope this gets fixed soon.

Hello, Is there a possibility to change the thickness of the round ports? The thickness is 36mm by default and it seems that it is not possible to change this value, or at least I did not find it. Cheers,

Dear all When i'm modelling an Dayton Audio RSS390HF-4 in speakerboxlite , i doesn't reach the maximal cone displacement. Doing this in WINISD i have allways the problem with the same datas that the cone displacment going out of limits, which is normal wit

SOMETHING ISWRONG W THIS. IT NO LONGER SHOWS ME MY CREATION IN 3D....8-(

How big should I make the box and I wannted to make it vented and to go as low as 35 or 40 hz

So I have a 2001 Jeep Wrangler hardtop convertible that I’m trying to build a box for that would sound good with the top off. My customer wants to go ported but as soon as we remove the top the bass is gone. Is there a certain way I should be facing both t

Any way the user can label the individual graph entries, or their shadow text boxes?

I’m using speaker box lite quite a lot to fo quick enclosure calculations. However, when I want to select a maker, say SB Acoustics or Faital Pro, I try to seach the database. However, no matter what I search for, the database comes up with the same makers

Is anyone having trouble out of the cone displacement graphs? I haven't had any problems until today. I modeled a new driver in the app and there is no way the excursion graphs are correct. Every single one are basically showing the driver self destructing

So I designed a subwoofer in SBL, basically a 325mm cube with an Dayton Audio Ultimax UM10-22. The graph in SBL shows 40Hz at -3.8dB and 30Hz at -6.2dB. Now I built it with a Monacor SAM-300D and measured it with my UMIK-1 and REW, and it measures 40Hz at

Can anyone explain how to create single sided and double sided trapezoid boxes on this site? Im building a two sided trapezoidal box for my 2012 Silverado that'll fit under the rear seat. for one of these.

When I try to enter my material thickness of .75", the text box automically resets to .03" No matter how I type the number in, I cannot get .75" to stay. Also, when calculation my port length, the calculator throws out crazy numbers. For example, if I want

I've been building speakers for many years. I like the fact that this is a web based solution with quite an extensive database but I am finding a discrepancy between my other tools and this tool when it comes to using multiple drivers. When I go from one d

so i want to build a speaker box for 2 alpine s-w10d2's but the only problem i have is where it gives total volume and useful volume is the useful volume the net volume or what?

Not sure what I'm doing wrong or I'm reading the 3d box wrong. My rear chamber is supposed to have the larger volumn tuned lower at 35 than the front with the basket inside the chamber, on the 3d diagram the basket appears in the front smaller chamber. The

I have an old subwoofer whit a blown out 10 inch speaker - enclosure is ported. I will put in a DD210 S4 speaker because I have an 300 Watts RMS amp for 4 Ohms. I designed a box with same volume and same port size just because I want to know how it will pe

Hello, could you please help me finding the T/S Parameters for the speakers - pictures bellow. I have two speakers, the only thing I know about is the Serial Number or Part Number. The bigger is FSF06401C-01 and the smaller is ESB545017-1808. Do you guys K

is there a way to measure corner radius? especially when its not 90 degree corners (building trapezoid style boxes)

Why is the port speed different between simple and complex computation models with the same project? Under simple it calculates over 50 m/s at 17 hz (box tuned to 20hz using 200w rms) but under complex it calculates only 15 m/s. Curious of the explanation

Isobaric calculations don't appear to be working right now, my understanding is that the low frequency efficiency should improve with two drivers working together, however the results for one or two drivers in the same box are always identical. I'll add th

Can anybody give a quick run-down on the rules that apply to a T-Line enclosure. The port size in relation to the sub size etc. Minimum port length for 10", 12", 15" subs. Sub up port back work the best.

Has anyone figured out how to fudge the box parameters to obtain a reasonably close simulation of a ¼ wave enclosure? Any Tline at all???? Or does anyone know of a resource where I can access a program on the web or mobile application. I do not have a comp

Hello, I was just curious as to when the next update of the drivers database would take place with submitted requests? The only reason I ask is because it is stated when adding a driver..."Attention: the result will appear in speakers list only after moder

I’m trying to design a one sided trapezoid box that is downfiring to look more stealth. But I can’t seem to figure out how to get the sides to come down and create feet. This way the cuts would also include this element. 

Hello, So, I'm playing with a the design of a new enclouse. But I'm having a issue with the options. I want a one-side trapezoid rectangle box with a labyrinth port. Being the angle side at the back and the port at the front. The problem is that the "walls

Okay im experienced box builder, but totally stumped on this one. Just happens to be my personal set up. I own 2 dd2512c and I am wanting max flat response. And it's recommending a sealed enclosed which the manufacturer does not at all. Vented 2.5 I have l

I have chosen speaker but the box, speaker, port models are not displayed in the "3D" tab. What is a trouble?

It is maybe a dumb question, but I'm asking this, because I heared about those port styles which are aviable in SBL designer - called exactly the same like in SBL designer, or also some people calling round port as "tube" port, or something like this, but
