When the PS was first reviewed a five channel setup was about $6900. Or $900/ea main, including the center and another $2400 for the pair of subs.
But now JBL shows two different prices for the PT800. On the PT800 products page they show MSRP of $1700/ea. At the Harman online store, under "specials" they show refurbs for $1050/ea and the regular MRP of $1500/ea.
At this time, the PS is still JBL's rop of the line, dome tweeter based system. The Project Array, K2 and DD66000 are all horn loaded systems.
