Version 5.4 is now available.

Updates:
Rebuilt the 2-way and 3-way crossover sheets with more advanced formulas. You can now choose up to 8th-order Butterworth and Linkwitz-Riley crossovers.
Justin, Thank you again for this.

Using it now and for some reason it is not generating a text file for the mid-bass on the 3-way?

Shoot I didn't adjust that part. Thanks for the reminder.

In the meantime you can cheat it by exporting twice and changing the midrange frequencies to be your midbass driver for one of the exports.

Thanks Justin! Now when you help me tune my truck this fall we have even more tools to work with ;)

---> download version 5.4 from my dropbox right here <---

I had an issue when exporting the curves..... I used White-Ledge, entered my crossover points, then exported to my hard-drive. The Mid-base-xxx-xxx.txt file is missing. Also, I got an error when using "House-Curve" ... error on line 94, and gave me an option to go into edit mode...

There is a work-around to get the midbass target text file while Justin updates the spreadsheet:
Set up the midrange on the 3way tab with the freqs/slopes of your planned midbass, export the files - find the midrange one and rename it as the midbass.

I fixed the Midbass file not being created on the 3-way sheet. Please download version 5.4 again.

For the error on line 94, try using the updated version 5.4 and if you get an error again please take a screenshot of the error message and then follow any prompt you get to debug or edit and take a screenshot of the code that is highlighted or that the program points you to.

Justin, have a hopefully quick question that I was wondering if you ran across in your acoustic studies. I’m trying to figure out the name of the phenomena of a bigger driver having more impact. I’ve tried this with various sized midbass drivers and larger drivers have more impact (feel in chest) than smaller drivers playing at he same output level. I’ve attributed this to larger drivers not having to move as far and snap the air more while smaller drivers have to use more excursion and push the air more. I’ve known about this for years and it has always bugged me that I don’t know the physics behind it and what it is called. And if you’d rather I start a new thread,I will do that. Thank you. :)

Yikes, who made this thing? Must have been me trying to get it done fast instead of good. I see the problem and I'll fix it next. Thank you for the screenshots, they are perfect.

While I'm at it, does anyone have a feature request? It's been a while since I've worked on this project and now that I'm on a roll this would be a good time to make this tool a little better. It could be something like "I want two custom curves to play with" or "the time alignment sheet is clunky and challenging to read" or something. I feel capable of a lot more after taking some acoustics classes so it might maybe be fun to try something I felt was too hard in the past.

Feature request 1: Allow microphone input
Feature request 2: Tie that into RTA and a DSP
Feature request 3: 6x120 amplifier
Feature request 4: Auto tune all of it for us like dirac live....

Not too hard to implement right ;)

Could you implement the BCAE wire calculators for size based on length and wattage stuff? I don't know how hard that would be, but it would be cool.

Just wanted to pop in to add my "thanks" for all the work Justin has done on this spreadsheet. Such a cool and helpful tool.

Also for Justin or anyone else in the area, MECA West Coast Regional Finals is this weekend in Riverside. I know it is a long drive, but it would be a good opportunity to hang out with a lot of car audio nerds and hear some great cars. If you aren't otherwise occupied, consider making the drive.

I've got a reasonable feature request:
Add the AudioFrog house curve as a built-in selectable curve, with some smoothing so it's not stair stepped like the original.

Were mine unreasonable???? :confused: :p

I just know Justin and I both dream of an amp that can do that and be super easy on the end user part. Kind of like the kicker key combined with dirac live and a beautiful 6 channel amp......only better!

Not really, I just thought mine would be quicker to implement. :)

Sorry dgage, I do not know a name for what you are describing. If you figure it out, please tell me :)

Have you tried using the custom column to to make this?

Feature request 1: Allow microphone input
Feature request 2: Tie that into RTA and a DSP
Feature request 3: 6x120 amplifier
Feature request 4: Auto tune all of it for us like dirac live....

Doesn't sound too bad. I'll see what I can do.

I added a new worksheet called Power Wire and Fuses just for you. It's the last one in the workbook. Take a look!

:shifty:
