I have a Mackie mixer on top of my M400. Could there be any possible magnetic damage?

Greetings All,

The MK-I/II speaker magnets are low enough and  distant
enough not to cause any gradual degredation of tapes.
During normal operation ..... If a tape breaks,it will brush past
the magnet and partially erase the tape. LH Tapes 1-4 from
Gordon's ex-MK-I had noticeable drop-outs of audio.
Someone/something wasn't careful.....

The inverse squares law of physics applies to light , electricity,
and magnetism.   Ken M. was taking the proper precautions
during MK-II tape change.  I probably would have unbolted the
Wharfedales to make 100 % sure.

BTW, the JKMK6 has magnets even closer to the bottoms of
the M400 tape-frames within. No problems seen in two years +.
I installed mu-metal (mag. shield) adjacent to the spkrs.
to preclude a future disaster. My pro-active policy of safety.

That's why we 'Tron users cannot stress enough the need to
keep headblocks demagged,non-magnetized hand-tools,
electrical precautions when installing headblock cable,
yada,yada, yada.....

Cheers,  Jerry K.
