A groove only 1mm wide - this is absolutely new for Topakustik products. This very fine groove is of course much less pronounced than the 3 or even 4mm wide grooves. This fine groove is made possible by drilling the back side deeper, which reduces the groove depth by 1mm. With TOPAKUSTIK® Classic 5/1M, the collection is completed with another groove to further increase the individuality of the design.
