[QUOTE="bbeljefe, post: 8160458, member: 655960"] If you look at the above graphs you'll notice that all of the models are flat at or very close to 50 Hz and the two flattest ones don't go -3dB until ~60 Hz. So no, there is no rule that says 4th orders tuned low can't play above 45. And yes, depending on the application, some will play well above 50 and others not so much. That's why it's a good idea to model a lot of different boxes for the same driver before making a final decision... so you can get the maximum bandwidth. Unless you're building a burp box, of course.
