For my HT, I am going to use the EP500, probably, but the EP400 is for my living room with the W100 and W22 combo, because of the extended upper base. It will probably be used about 60-70% for music and 30-40% for TV/DVD/BD. I'm afraid that I would have a big hole in my music, somewhere between 100 and 500 hz if I don't.
