The mechanical and acoustic design enables vertical columns up to 24 loudspeakers to be hoisted. The J8 column speaker pa system box is made of birch plywood and coating with impact and weathering protected PCP (Polyurea cabinet Protection). The front of the loudspeaker cabinet is protected by a rigid metal grille, and the side and rear panels contain four handles.

The J-SUB subwoofer is a low frequency reflective design with two-way low-bass speaker, loaded with 3 18 "Neodymium woofers, of which two are facing the front panel, one facing the rear panel.

J-sub speakers can be used in different combinations with J8 column array speaker, such as stackable or hanging, can be centrally suspended on the J8 array or can be used as a separate set of sound columns.
