In Ney York 1994 and heard exactly this pair of Wilson X1 at Sound of Singer.
The serial numbers are 1/17 and 2/17 manufatured 1994.
I bought the speakers in the US back in 2009 and shipped with DHL to Europe.
I have the wooden boxes fo shippment.
I have the user manual (copy I ordered from Wilson Audio in US)
I'm currently driving the speakers with a pair of Krell 450Mcx connected with Taralabs The One speaker cables.
Speakers are 25 years old and never be repainted so there are dents in the painting.
Speakers are painted with one of Mercedes Benz colors from 1994.
Membranes and suspensions are in good working condition.
