To answer you question, you will not get anything close to comparable quality from a sound bar.
So, without more detail it is not possible to advise you.
Is there another space in the home to put your system?
If not pictures would help.
Designing elegant systems is certainly possible. It is possible to get good results and have elegant design.
May be a small bookshelf system would do the trick. This is where pictures really help.
Another possibility is an elegant in wall system.
If there is a place to build a false wall that can really help.
In our new home we are building, my wife wants a good system she hardly wants to see. I personally did not want a system in that space but she does, but does not want to see it.
So I'm using the space to the left of the fireplace chimney breast.
So this is a 3.1 in wall system that models well. Time will tell whether it is any good.
Right and left tweeters are around 7 feet apart and the tweeters 36" above the floor.
If the modelling turns out correct, or even if not the crossovers can be modified according to results of measurements.
So this should fulfill my wife's sonic criteria and have good WAF. All that will be visible will be the TV screen and the speaker grills.
So you do have some options.
