Not that I know much, but I think the consensus here would probably be, "yeah, go for it". With the addition that many people are using bass augmentation, the only real question being when to bring it in. Shoot, it is so easy to do a test baffle even I can manage it. Punch a hole in something and stick in your drivers. Even a drywall board can work. Easy to model. Add cardboard with tape to adjust the shape/size and you're on. You've heard of it, now you gotta try it.
What exactly is the Coral tet-1? Do you have pics? Is it like a beta?
