What is the difference between “Bottoming out” a sub, and blowing the driver with too much power? When I explained that I upgraded to a 20-39 PC+ sub from a 16-46 PCi sub due to room size and “bottoming out” concerns, he simply stated that the physical room size should have nothing to do with the sub’s performance. His argument is that when a sub reaches its excursion limits, it should simply drop off, instead of “bottoming out”. Based on everything I have learned from you guys, I knew that room size has a great deal to do with it, but I could not explain why, nor could I explain how “bottoming” a sub relates to it reaching max excursion (physically, what is happening?). I am thinking it has to do with air pressurization as a function of room volume, but that’s just a layman’s guess. Any help would be appreciated! “Tank u veddy much.” (latka gravis-esque)…..
