It is “solution” @asvjerry - As in everyone chucking out multitudes of ideas to try and solve the problem. (Hence it is a shower of things and ideas in “solution space”.)
Maybe I should have said it is like playing pin the tail on the donkey? (Where we blindly take a stab at it?)
But I like analogies which paint a sort visual description, and i am a visual learner.
In any case I figured it was a head rest of sorts.
And certainly much easier than a new set of speakers that waver the sound opposite of the comb that the chair provides.
But in theory one could use a DSP and inverse comb the FR to make it flat in the chair… If the OP had a DAC with a parametric EQ it should be relatively easy to try… that would be a pretty cool thing to take a crack at IMO.
How is NC at this time of year?
The relatives will be going from near you, up to the VB area around thanksgiving.
Enjoy the fall.
