Presonus Eris Pro Sub 10

I bought this to use in my home studio (6x7 meter in size), to pair with two Kali LP-8 v2 monitors, although this subwoofer has all the right settings needed for it to work with any monitors, even if your monitors don't have any adjustments, since you can adjust the crossover point between subwoofer and satellites via the built-in high- and lowpass filters, etc. It sounds fantastic, after I found the right placement in my room. Even though the Kali LP 8s are great by themselves, this subwoofer noticeably adds punch and bottom to things like bass synths or kick drums. Only downside I can find is that the power switch, volume, etc, are all adjusted on the back of the subwoofer.
