Not really a soundbar but actually one of those all in one, supposed high end music boxes that rely on retro styling to justify the price.
While more and more of these devices offer ARC and sub pre outs, they are PCM 2.0 only affairs and cannot be expanded for more channels.
If a fan of JBL, a simple 2.1 system that can be expanded could be had for about the same money using a JBL MA310, JBL 250B speakers and a JBL Stage 200P subwoofer. The speakers can be positioned separately and optimally in the room. This cannot be done with all in one units.
