Any speaker cone can bottom out. In fact, smaller speakers are more prone to bottoming than large speakers. The situation occurs when the speaker tries to reproduce high levels of signals below their operating range.
This is one of the reasons that 2- or 3-way speakers have crossovers. The crossover prevents say, the 4” midrange from trying to reproduce low frequencies that are better handled by a larger driver.
