Any soundbars with built in subwoofers worth looking into?

I am looking for a soundbar for my outside covered patio but do not have the space nor want to put a sub on the ground due to the weather. The soundbar will be mounted underneath the TV and covered when not in use and during rainy weather and all removed during the winter. Not looking to break the bank due to the fact that this will be outside and is still susceptible to humidity and high temps.
