These speakers, I would think would want something bigger with more current output than the RB-1070 to perform at their best, especially in the bass.
Sterophile measured tests on the Focal Chorus 826W
"With a minimum magnitude of 2.9 ohms at 118Hz.
There is also a current-hungry combination of 3.83 ohms magnitude and –53° electrical phase angle at 94Hz, a frequency where music can have high energy levels."
