This is from the datasheet:

Quote
Meridian SpeakerLink connectivity makes
M6 quick and easy to set up and to install,
and allows the advanced audio controls
offered by M6 Loudspeakers to be managed
from the front panel of a connected Audio
Core, further simplifying installation of M6
Loudspeakers.

Bass, Treble, Balance, Boundary Gain
Compensation and other features can be
controlled directly with an Audio Core unit.
The M6 has no full display of its own, but
level and other settings can be shown on the
panel of an Audio Core.

No mention of processors etc.
