Why is it effect better? It is not just casual to say, the built-in speaker units and the cabinet panel form a horn cavity, which increases sound pressure of the direct sound wave, reduce the treble diffraction on the panel, and then sound field becomes accurate, resolution of midrange and tremble is improved, there is a classic example that J B L flagship series that uses horn design.
