Pretty accurate, helpful for quick sub box comparisons
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
