Hi Pete. I did serious, high-end car audio design and build in the early 90’s, and with an engineering and computer programming background, I wrote many of my own tools based upon the original T/S papers and measured drivers using techniques that were only just barely starting to factor in listening space. I stumbled upon this video, and am absolutely blown away by how detailed and thorough your engineering process has become. I am HIGHLY impressed!

I can't expect a reply to this given the age but nothing ventured... I've watched this more than a few times now and there's one tool in the chain I've yet to identify. At about the 4:00 mark there's a graphic that I think is showing SPL (or energy) at various locations in the vehicle. There was a brief mention of "acoustic Abaqus", which I assume is some acoustic tailored version of the FEA software package. Yet it was not listed in the tools used. ReW was listed but though I've not used its Room Simulator, I don't think it produces this level of data. I'll assume, though not really needed, the graphics depicting the data was done via Blender. So how was the data depicted above generated ? I'm curious because although my engineering background is in radar, much of the concepts and principles apply across the fields. (No pun intended) Fantastic video, as always. Much appreciated!!

It seems that "HexiB" wrote his auto interior modeling as a huge set of spreadsheet calcs some time ago and is still using this. I'd really like to know what approach he took and just how deep the simulation goes in trying to include all the real world effects. Room EQ Wizard has a room simulator, that I've never used, that does some simplistic modeling. I don't know how well either does in modeling and if they've ever been really validated. Obviously not every crook and valley is included and the acoustic properties of the various surfaces is at best 1'st order guess.

This is outstanding! I didn't know someone would really go to that much effort to simulate a loudpeaker enclosure from start to end so that the frequency response it creates in a specific environment matches a predefined curve at the listening position. Two questions: 1) What simulation software do you use? How did you achive live-update of the simulated frequency responses while tuning the parameters in CAD? 😧 2) 04:27 - Equal Loudness Target. Why do you want to match the equal loudness curve in the first place? Producers create their music on systems that follow a rather linear frequency response and not one, that follows the shape of an equal loudness curve. So why should our subwoofer do? In my view it just adds a colouration to the low end sound. What am I overseeing?
@IODBaaL Жыл бұрын
Yes and no. There are different problems at the same time when mixing music. Yes, you could compensate in the production or mixing stage of your music BUT: the lower the note the bigger the wave and less space in the mix. So when compensating for equal loudness you'd have to limit different notes differently or you overdrive very low notes, so you only do this in a very rough way eg. octave jumps
@Elliott-Designs Жыл бұрын
I agree using the Equal loudness contour diagrams in this way does seem odd. I've only ever used it for comparing differences at two different volumes and compensating for that so that the content sounds the same at a volume louder or quieter than the reference. I can't quite see why he would try to trace the contour in this way. I'd like to hear his thoughts on this.

1) This is really interesting to me too... I'm pretty sure he's taken advantage of OpenSource CAD editors so he can easily write and run a script (possibly written in Python) from whatever operating system he's using (in this case, Windows). The script periodically extracts data from the CAD file and parses it into another text file, which the Sheets editor can then read in real time. This can be achieved using plugins or macros. Afterward, it calculates and prints data and frequency responde charts using macros within the same spreadsheet file.

I do understand that enclosure design if we want it to be perfect should be left to professionals, even driver choice and amps and in some cases even vehicle choice, but say we have some vehicle and some driver for which we have parameters and we roughly want it to be in specific place and have limited size available what would be the best approach to design and build enclosure which would not sound bad. For good sounding one we know who to ask and what to do, but how about some simple diy not bad sounding project which is not sensitive to millimeter precision errors which can end up more like centimeter beginner errors in build process for example?

I'd still love to know what the simulations software is. Either I blinked and missed it or he didn't tell?

Absolutely amazing, I understand some of it and can make sense of most of it (having watched this video more than 10 times because its just so cool) except the FreeCAD. How did you make FreeCAD do that?? I have been really interested in the electroacoustic world for years now and I have never seen such an in depth design and simulation software setup. I imagine it might be a bit off topic for the channel (and a massive ask) but if you made a video explaining how the FreeCAD software is customised in this way I'm sure a lot of people would be really interested. (I know its been over a year since this video came out, I've just never had the courage to leave random comments so just don't comment, but here's one anyway).

This is amazing! Would love to understand how you get your FreeCAD speaker cabient designs into your modelling software in real time. Really impressive

Do you use a combination of the air flow analysis of free CAD and excel spread sheets? I'm curious what the program is that's open on the same monitor as free CAD

my yamaha subwoofer has a "yst" system (yamaha active servo tech), would a system like that have a effect on the design of the enclosure? the yst would make the ts parameters and such from the driver itself unusable? would they measure the driver with the yst system active? or arent they matched at all and could use any random 10" driver?

I thought I knew a little bit about sound enclosures. But, even from an engineering standpoint I was lost in the first few minutes. This dude is Way-Way beyond me. They say a picture sais a 1000 words but even this video doesnt say enough for me to understand... and I've watched it 2ce. I'll have to stick to micro's...

Great modelling methodology and an amazing video as per usual too! A bit baffled as to why you used the Equal Loudness Contours in this way, but nonetheless, an amazing showcase of your workflow. Thank you!

Please help explain: This level is above me and have some basic questions. I understand the bass distance is based on the hz it is played at, 28hz around 34 feet. But does certain box enclosures change the distance of the apex? Or is it just the note played? Is the apex also the completion of the frequency wave? Or the whole wave length? What would be the order of distance apex be- sealed/passive radiator/ported/4th order/horn?

When I specified my sub enclosure, I asked for sealed because I thought this would give me the most accurate response as it related to the kind of music I listen to which is metal with heavy double bass. In my experience a ported enclosure resulted in inaccurate sound at higher volumes. Is this correct? Should I have considered other designs?

This video is a bit weird in that the client wanted only up to 60hz and already had a driver/speaker. Ported designes are good getting more efficiency way down in those low frequencies where a ton of power is needed exponentially as you get lower. Usually crossover in a car sub will be higher than 60hz, depending on the car/situation (and as you noted, the playback content) ported design will struggle to provide tight bass when crossover is set to a more usual 100-150Hz, as most car 6x9 and door speakers still struggling down there. So barring some other low-mid solution, this client must have a big hole between 60 and wherever the other speakers come into their own. Maybe this is just for some competition thing

Probably should have stated your concerns about this and let him do the work. I am pretty sure he would have recomended the best possible option for your specific situation, no matter what it would have been. Like you see here, there is a lot more to it then the general simple rules people like to use/talk about. They probably hold true in most cases when you or me design a box ourselves. But probably less so when you are able to model basicly anything to perfection.

@@baronvonlimbourgh1716 The thing is, his perfection is only as good as model of the cabin he's basing everything on, and it's far from perfect. _Garbage in, garbage out_ Maybe down below 60hz it's fine as the waves are huge and rudimentary model works, but things get tricky as you get into the region between sub bass and mids You can engineer to the nth degree of perfection, but you also need to see the big picture, ask the right questions etc. Client may look at marketing for their 6x9s and tell you 60-80hz is a good crossover point, big picture outlook and experience will tell you that's not realistic. When client turns around and complains about loose muddy base, blaming client because they specified 60hz maybe technically correct, but still a design failure nonetheless

@@Username-qx9gk if that's the case, that would have been the exact advice he would have given him, wouldn't he? The OP is now questioning his decision. Would he have stated his concerns he either would have recieved a better sounding system or he would have had his experiences confirmed and would be confident what he has recieved now actually also is the best solution for his application. Pretty straight forward.
