I bought this equipment there few weeks and I've looked everywhere how to adjust the bass, because the sound was too powerful in a poorly soundproofed apartment. Nothing to install, simply use the sound card's software, in my case, I go to the file explorer, "C: \ Program Files \ Realtek \ Audio \ HDA \ RAVCpl64.exe" I created a shortcut and playing with the equalizer, I manage to drop this bass effect. I recommend this material to desks, average room, home use, the price is interesting and rendering is good, no interference with other devices. Small separate control to mute and adjust, very convenient. The box takes a lot of space on a desk by cons, but at the cost of great music!
