Give it a shot

This is a very useful app. Much more than anything currently out there on a Mac platform. The $5 fee to check it out isn’t bad, but I have a problem with not owning my tools. I would pay a good amount for this to be purchased then maybe subscribe to their speaker database. Otherwise I’m going to use it this one month and then probably wait around to see if any other programs pop up before I need it again. Maybe that model works for some but you’re leaving money on the table from me.

Used for a few hrs then paid for pro version

Was working well the 3 D box and first day using app it crashed after about 2 hrs 😳. Had to delete app and reload. Still didn’t work till next day. 😖

🤗 Well the next day it loaded up and worked, I been on it testing it out, it seems to be working well now. If it doesn’t crash anymore I like do like the app.

🙌🏼🔥🙌🏼 Ok it’s been a week or so since last I wrote, and I have been designing many new different box’s, and I must say the app is working very well, and saves all my designs!
So I must say I am loving this app now, so I,m giving y’all :
5 stars 🌟🌟🌟🌟🌟 for a great tool that does the heavy lifting so much faster that I used to have to do it by hand/myself. 👍🏼
I also love how the data base has so many subwoofers 🔊 loaded and when you pick the one your using it adds all the info in for the build, nice 👍🏼

Hello, can you write to the support email and describe the problem?

Subscription required

I could see paying once and being able to use it but the subscription is ridiculous! I subbed twice and got little use out of it. The cut sheet also shapes it oddly. It would be a lot more user friendly if it calculated cuts as perfect rectangles instead of making us do L shaped cuts. Not everyone has the tools or workspace for this. Even when I lived in a home with a garage, my tools were limited and getting perfect cuts wasn’t easy. Home Depot did the crucial rectangle cuts and I just had to sand a bit at times. I don’t want odd shapes. Paying monthly to be able to use the app is not worthwhile. Ultimatecaraudioapp is light years ahead of speakerboxlite... the cut sheets aren’t as in-depth as far as the port cuts, but it is still much better than this app.
