I wouldn't ever say there was a "best" subwoofer for any application. The SA's are a pretty versatile driver and would likely do well in your application however there are numerous other subwoofers out there that would do great as well. In the end its going to come down to personal preference . You might find you don't care for the sound of the SA's in that enclosure while another subwoofer sounds just right to you. The SA would be a great start but whether its the best for your application depends on you and your listening preferences and system goals.
