I recently listenend to a pair of NS1000 speakers at a friend’s home. They are available for sale at $2800. He bought them new ans has kept them in pristine condition, he even has the instruction book that they were supplied with.
He has upgraded to big 15 inch bass drivers and horn mid and treble. A small group is going to visit him early next week, if anyone is interested send me an email: firstname.lastname@example.org
