There are many factors at play. First and foremost, you'd need at least a 280 watt model. The larger the enclosure, the larger the speakers. You'll definitely want a six speaker version with a sub woofer out (analog wiring to a larger sub is preferred to a wireless sub).
Wall mounting makes a huge difference because of the resonance added by studs and drywall.
Now, does it compare to a Bose 5.1 system at five times the cost? No. But it can be a very effective and elegant solution.
