I got this app expecting some garbage that wasn’t worth the $5, but I was pleasantly surprised.It’s actually pretty close to real world scenarios and overall I like it.BUT….I will say someone that doesn’t have much car audio knowledge will struggle.TO THE DESIGNERS…will you please make an option for more than 1 round port?The way it’s set up now, the calculations aren’t accurate if you have more than 1 port in the enclosure.And maybe an overall explanation of what specifications are needed for say subwoofers, boxes, etc…Not everyone knows how to calculate subwoofer “sd” or “bl” nor know where to look. That would just make it easier for everyone, mainly people just beginning or just don’t know.Overall though, I’m pleased with the purchase

There were some bugs that made it impossible to save the Driver, Enclosure, and Project. They fixed 2/3. Driver and Enclosure can be saved, so I don’t lose my T/S parameters. Enclosure saves as well but it only lets me save one enclosure, so I can’t load different boxes. Project only lets me save one project as well. Overall the frequency curve looks okay, but I feel like under Enclosure the port area and lengths don’t match up with WINISD, Torres, and Ultimatecaraudioapp. I don’t use Calculate to find the frequency it’s supposed to be tuned to by inch2 and length.Still it’s a big improvement and the frequency curve somewhat matches up with my last sweep on SPL Lab

I love using it. Would you be able to add landscape mode? Also be able to change the plots cause my graph gets cut off and I can’t see the numbers especially when it’s low tuned.

This is a pretty good app! A help section would be great. I have a couple questions. When you use a rectangular port does it change the net volume to account for the port volume? Does it calculate rectangle ports as using common walls?
