The 3677 I ordered is still waiting production as its not in regular manufacturnig anymore, should arrived dec-jan
But , the local rep tried to help in the meantime because of all the delays, and arranged for me an older model - Jbl tr125 which was used in an actual commercial cinema (before this they offered me the new 211 but its HUGE, I mean its 100 cm wide, even for me it seemed too much)
After I hooked it up in my living room to denon avr (no ext amp) I can tell you I was absolutly stunned. it just took command of the room. overall clarity/dynamics is superb, vocals are big and natural, details and midrange are clearer then ever. audysssey XT set it in -12
and still it sounded great , although I decided to turn up a bit manualy + turn up dialogue level and its even better. even at higher volumes its not fatiguing at all.
I was worried my LR svs ultra bookshelves will not be a good match but to my surprise it sounds fine so far. but I keep checking as I go.
I stared with few 5.1 trailers, LOGAN sounded out of this world, also "kong", "Jedi", some dolby/dts demos.
had time to watch "the great wall" (really, really bad movie but it sounded great), one scene grabbed my attention, when warriors on the wall played the big drums together. I dont know if consumer speakers can sound as live and musical and just cinematic as that scene was created on this speaker.
