The Voxel sub has always been known as one of the best small subwoofers on the market. The main concern was always port noise with higher powered amplifiers and the ability to have a front firing subwoofer. This design fixes both of those concerns. It is not only front firing, but also has a front slot port that is designed to give maximum output with low port noise. This helps you get the sub you want with the sound quality you deserve.
