The latest version ruins the Hyper-Low Bass and Super-Low Bass. The first one used to go from 31 - 44 Hz, and the second from 45 - 88 Hz in the previous 1.2.13.0 version. Now the latest: the first bass from 62 - 85 Hz, the second: 85 - 157 Hz. I really want them back, but I don’t know how.
To be honest, just use 15 bands instead. The wheels on the 10 bands are inconsistent. It’s like they change the range of them for each update they roll out. I’ve experienced this too, and the only way to get control back of the very low freqs (or the really high ones) is to open FxSound from the system tray, click on the two opposing arrows icon, and from the bands dropdown menu (the one that says 10 bands with an arrow facing down next to it) choose 15 bands.
