Not as good a deal as previously but still 25% off the usual thousandish.
They have been as cheap as $560 but not for quite a while. $599 seems to come up a few times a year but I'm keen for better speakers and my R1700BT pair will be happily connected to my gaming PC.
Edit: Also $699 + Delivery at MWave - Thanks xoape
26/11/21 - deal is current again, I guess for Black Friday.
