I have the Polk Audio LSi series ( that is,
LSi15's for the front, LSiC for the center,
LC265i's for three rear surrounds ) and
I am in the process of upgrading a
James Loudspeaker EMB-1000 to a
Velodyne HGS-15X.
The Polk's are outstanding for movie content
and from good to very good for music, that
is top end is great, mid range good.
Looking forward to the HGS-15X!
