Not that anyone is still interested in this topic, but I have two JBL Performance Series multichannel systems: 5.1 for music and 7.1 for HT.
The HT is set up in a dedicated, completely light controlled and sound controlled room. It's set to THX standard and uses multi-subs (PS1400 and HTPS400--two each), six PT800s and a PC600, along with the Performance Series (aka Lexicon) electronics. The room is right in the sweet spot of room volume for this Ti direct radiator system, and it's simply awesome.
None of my buddies, most of whom spent a lot more money, has a system that can match it, and their constant lament is "Why doesn't my set up sound this good?"
Of course the answer is easy: you didn't bother to treat the room, you didn't bother to buy speakers that fit the size of the room, and you didn't get it set up properly. And this last bit has a whole lot to do with JBL's whole system philosophy. In addition, these Performance Series speakers are stars in their own right.
For the 5.1 music system on the main floor, it's in a large open living space (1600+ sq. ft.), well away from any boundaries. It's two PT800/PS1400 stacks, three PT800s (one as center) and an HTPS400 as the .1 LFE unit. It's ridiculous how it performs when given that freedom, and it easily fills the entire space.
I'm not a big fan of horn-based systems in the home, though I have a few horn stacks down in the music room that can really rattle the whole house. So I was very happy to find these Ti inverted dome wonders from JBL that really took my breath away the first time I hear them and sounded even better when we finished setting them up and calibrating them at home.
So there you go; I liked it so much, I bought it twice, both for music and movies.
