If there is a best buy near you look into last years HW-N850 sound bar, there are out of box demo model available, many were never even plugged in or used. 370 watts atmos system with sub, you can actually put 300 or more dollars back in your pocket. I got mine with a couple of small scratches on the sub for under 400. BTW a black sharpie made the scratches go away. Sounds awesome and would more than do the job you are looking for without getting rears. Good luck
