First issue..I've dealt with Creative via soundblaster issues etc in the past , So many problems with long term support and long means like after 1-2 years in their world.
Second problem is obviously price on a sound bar , regardless of how many "Chips" they toss into the mix/propoganda its alot esp for a bar.
Third overall I personally have a 7.1 Surround sound system from Yamaha . it works fine but literally a large chunk of things i've found to hear on it don't 100% or at all support surround or proper surround anyways.
Either its 2.0 or 2.1 or fake 5.1 rarely full dolby etc Very VERY rare is it 7.1 5.1 is somewhat common now but even when its full dolby if i tell the unit to do 5.1 or 7.1 it sounds the same over all usually. Often even if i force 7.1 it mimics front back and bass and it sounds the same as 5.1 .. not much has changed unless its the absolute top quality stuff which is rare and then you can tell.
Sound bars are cool in a way they mimic surround sound often well enough for what ever.. and they dont require wiring etc this is a given if you have a limited room esp id wait for user personal reviews myself before buying into creative videos or even bought off reviews from AV sites is all im saying, maybe its amazing but wait to see.
