For me, yes. For sure. I felt like I got new subs again. I have a couple of room modes that are pretty nasty. Lemme see if I can find a "before"...

God that's so ugly, lol. The above is with no room correction at all. Audyssey and DEQ are off and the Mini is flat. There are multiple sweeps because I was trying different crossover points to see what would happen. I labeled them all so you can tell which is which.

This is after running Audyssey. I'm actually pretty impressed with what it can accomplish when you know what it had to start with. However, you can still see a fairly wide 5 dB dip between 60 and 90 hz and it's noticeable. That's well within the music range and my bass still sounded thin. It's much better but still kinda all over the target goal of 75 dB.
Then of course as the previous post shows I was able to use the mini to really finish dialing everything in for a nice even response.
