The refined subwoofer cabinet allows fast and accurate low-frequency response, making it best for dancing clubs, touring or installation applications.X-218SUB equips a long 21" subwoofer driver. Strong neodymium magnetism provides extremely high magnetic flux, which improves the efficiency of the speaker. A 4.5" voice coil minimizes linear distortion under uniform magnetic forces. The up-to-dated paper cone ensures the strongest rigidity and low move quality.
