I bet your room is nowhere the size of the OP's. Take your Deltas outside and see if they still rattle your eyeballs.I keep going back to my reference, the Deltas l own. I've just had plastikman, mind in rewind playing at very very loud levels, so loud infact my vision was moving with the B-lines and the air being moved felt like id just switch on a desk fan...... All from a 9" bass driver AND..... Its cabinet ports.
PS and it never flapped out of control once. I'm sitting 3.3m away from them.
