Bumping this up. Need to finalise this weekend. Please help

Hi, I think you are in a territory not many Beoworlder have wide experience of. i.e the combination non-B&O TV with current SOTA actives loudspeakers, and passives with separate amplification. Some of my points… 1. Subwoofer. Can add this later. If you are pre-wiring in a build, wire in for a sub. 2. We suspect that B&O will release a new sound bar in September. It is suspected that it may be a Beovision Eclipse sound bar of sorts with pluggable external loudspeakers and 5.1 processing. If true, this would simplify your whole home theatre approach…..

Yes, as below. I'd definitely wait as the Beosound Theatre is very close to release - a centre speaker / sound bar with all the surround AV processing built in. It will integrate with your LG and allow you to use the B&O remote. Also, the BL28's have such absurdly strong bass that a BL19 sub is completely unnecessary - many 28's users have had to dial down its bass in the out of the box settings!. As for your surrounds, etc - that's all fine and do whatever you need, governed by room configuration / budget etc etc. You can see a picture (which was leaked by B&O) of the upcoming Theatre on the B&O (not official) Discord server, under the BeoSound subject / thread.  

Definitely with you on overkill with the BL19. The 28's deliver amazing bass. AND I would definitley wait until the release of the new B&O sound bar
