Features:
Bass radiators, also known as passive speakers, are used in place of inverted tubes, radiator subwoofers, and traditional back subwoofers.
Low frequency diving depth and backward but speed is significantly faster than back type
The advantage of tightbox is that it removes the reverse pipe mouth, and produces wind noise.
Passive high-volume adjustable radiator delivers ideal tuning frequency and extra bass without adding amplifier power or enclosure volume.
Dramatically improves subwoofer efficiency and ultra-low frequency playback at high decibel levels.
