Focal Electra SW 1000 Be subwoofer

Does anyone have experience with the Focal Electra SW 1000 Be sub? I am planning to add it to my existing 1027 Be loudspeakers.
Did you add it your music system ? What is your experience. I am in same boat as you.

Please let us know your views on it.

after much deliberation, I bought SVS SB13 Ultra and it definitely can keep up with 1027 BE.
