There's no harm at all in having the horn exposed. Just make sure the rear chamber is at least 0.35ft³. As you know, the stock build has rear chamber behind the woofer extending all the way around to the sides of the flares. It doesn't have to be built that way though, the only thing that's important is that the throat cutout and flares be made as shown and the rear chamber be larger than 0.35ft³ Get creative if you like, make 'em a work of art!
