Roaming around the vast space of ISE 2014 one can spot some very interesting products-- such as the admittedly impressive Concert series speakers from Steinway Lyngdorf.
Steinway is most famous for its pianos, but it also makes very high-end audio products. How high-end? Enough to demand pricetags starting off from $40000 for a more basic (relatively speaking, of course) 5.1 system to up to $200000 for a gigantic Concert loudspeaker.
Introduced at ISE are the LS-R210 and LS-R212 boundary woofers, rear-firing systems promising the simultaneous arrival of first critical reflections and direct sound to listening position within a compact understated design.
