I have the Salk V seriesMonster Center - in fact it's the one photographed half way down on the Salk V series monster page.
http://salksound.com/speakers_vseries_vmonstercenter.shtmlIt would probably be too much for the Song Towers
but if you are thinking of the HT2 or HT3
this makes a killer center channel for Home Theatre.
Especially since most sound in movies is in the centers.
the ribbon tweeter, mid and two low drivers disappear in the room.
Details, Imaging and tonal balance are excellent.
I have it mated with a JL Audio F113 sub and it's an overwelming experience on action films.
If you have a HT salk setup try the new King Crimson Red DVD-A recording - it has material that sounds like it is coming from the side walls at the 2 and 10 o'clock positions - 5.1 and lots of interesting imaging
