Due to my wife being in charge of the living room, I can only have small, white stereo equipment. I just purchased the Bluesound Powernode 2i to power the passive Audioengines P4’s. I definitely need a sub to smooth out the highs and give me some lows. Due to size constraints I am looking at the new SVS 3000 micro, the Elac slim 2020 or the Rel T5i. My room has a low ceiling and is about 14 feet deep but extends to the left of listening area about 30 feet. Not looking for earth shattering base just a richer sound with decent base. Thanks
