I owned a set of X’s during the early ’80s - Problem with first-gen Acoustats like these is how the conductive coating on the panels can disintegrate over time - I discovered such delamination issues within ten years of use; this isn’t something one can readily see, instead sound quality is progressively altered to where frequency band is skewed from midrange through treble, no longer sounding at all cohesive (one speaker was worse than the other in this regard) - Unfortunately there are no longer any rebuild facilities in existence for these once premium performers - Just something to be aware of.
