My JBL sub is about 6 ft from the soundbar with no issues at all, BT should be able to do within 30'. Do you know how to get video signal on JBL soundbar via airplay and chromecast. I am currently using a projector with the soundbar. Trying to use my iphone XR to watch video on You tube but I can only get audio working, do you have any idea how to fix it Bro...
No fixed location for the subwoofer in your listening room. Trial and error is what I always do. The rule of thumb is you don't want to know exactly where your subwoofer is when you are in the movie. Immersive!!! My JBL sub is in the corner in the front in my mini home theater, in my main home theater room , I am using three subwoofers, front/Rear/side and they are pretty much around the king seat, in phase is a must!!!
