As I have never been able to hear the Adire Tumult in person I have no idea how they perform in the real world. I will soon be constructing a bass bin for my friends audio business, that will need to be able to play in large rooms. Most places, where this setup will play, will be ~1600 ft^2, but I would like to build it with the strength to handle 4000 ft^2 rooms if need be. As he will be playing a lot of Drum n'Bass type music, the setup will need to play with authority in large areas. Will 2-4 Tumults be able to handle this type of application in a vented enclosure? I have looked for tumult horn designs but have found nothing. Any suggestions at all, for creating an insane PA Subwoofer would be greatly appreciated. Thanks.
