Accuton C173-6-191 Midrange 6 Ohm 1 piece

The Accuton C173-6-191 is a 16cm bass-midrange driver designed for small bookshelf monitors. It features a mid-sized voice coil with 38mm titanium voice coil former for high midrange resolution and a long excursion design for high SPL capabilities. TheAccuton C173-6-191 is the successor tothe C173-6-095 and features higher excursion and optimization for smaller cabinet sizes.
