These are quality products from Sony with some trickle down technology from its high end SS-AR1 speakers which cost $27,000/pair.
I am super tempted to get 3 pairs, too bad that I am not in the US now and shipping would have cost me a bomb.
That’s a lot of money for a little speaker. Bass at 48Hz? Too shallow.
Well, please see beyond lowest frequency. This speakers can dig up quite a lot of nuances and details in your music.
