Don't expect audiophile grade components at such price:

wow a 5.6 uf cap and they couldn't spring for poly? I wasn't expecting audiophile grade, but curious to what was inside a speaker that Stereophile raves so much about....

The entire back panel, and the front baffle from the looks of it, are made of plastic. A very good reason for all that stuffing, without it this speaker would sound very hollow I'm guessing.

The crossover is disappointing, but about what I would expect from a speaker of this price. I used to own a pair of JBL N26II speakers, which had a surprisingly solid cabinet, but very poor tweeter, and crossover quality equal to that of this PSB unit.
