You need to decouple the speaker from the floor, it’s likely just vibrating through. Plenty of options out there, I used Auralex Mopads when I lived in an apartment and they helped with my neighbors.

Those Q’s were a huge surprise for me at Axpona this year. Definitely an upgrade over the Kefs. Don’t worry, you done good!
