From my perspective, there we very good loudspeakers made 10 years ago that easily compete with loudspeakers made today....BUT...how much risk are you willing to take.....
Its likely that someone who bought a $40k speaker 10 years ago and is selling it now took pretty good care of it. But its unlikely that the price has dropped 90% unless there is an issue... Nevertheless, the question remains how much deterioration has occurred over 10 years to the loudspeaker's surrounds and internal electronic components...and if there is a problem, can they be easily and cost effectively repaired or has the company gone out of business and/or shipping would cost a small fortune.
