[QUOTE="Rashaddd, post: 4904216, member: 592162"] that only applies to a ported enclosure though, because as you get well below tuning the port stops being able to invert the backwave of the cone due to wavelengths increasing, and it acts as though its in free air, which means its directly cancelling itself out. Granted you can still hear it somewhat, but much of the wave is being cancelled out. The reason you have the most output at 22hz is because thats where your port is able to most efficiently invert the backwave of the cone, which means there is maximum damping on the cone, causing a decrease in excursion [/QUOTE]
