reminds one of an nxt panel


I remember those from the 70s - interesting design concept but rather underwhelming IIRC - the little NS625 2 ways and NS690 3 ways were my personal favorites of the line


craftsmanship of both the drivers and enclosures put most of the Advent / EPI / Marantz etc mainstream products to shame, and I quite preferred the sonics to most of those brands as well
