Large or huge
The Skyline series boasts extremely exaggerated unit sizes, including an 18 inch subwoofer S118, a dual 18 inch push-pull subwoofer V218, and a 32 inch subwoofer S132 with enormous size and energy. These subwoofers are almost larger than the common sizes on the market. It also enables them to emit extremely low frequencies as low as 5hz (-6db).
If you are in front of Skyline, it will completely change the way you perceive low frequencies. Your body and eardrum will vibrate together in this space, and all of this is the most authentic appearance of bass.
