Yeah, they're super rad. I just can't see a manufacturer taking a 3D printed waveguide to heart, and it makes me think they're assuming worst practices. If they made a tweeter/waveguide series to match their woofers I'd be more inclined to take that to heart, certainly. I'm not impressed by their OEM implementations with third-party AMTs, however.The 6.5" mid is clearly more specific but not without interest. It seems intended to cover a 200Hz-2200Hz (high and smooth fr without distorsion) Give a 12" woofer, this mid and a waveguided tweeter to a good designer and I am all in. But I agree, it is maybe less a game changer than the midwoofers. If you need a waveguide tweeter, I suggest you give a look to somasonus.net (augerpro) free designs.
