that's a massive generalization; horns are anything but musical.
Yes, maybe some giant black creaky plywood cabinet on the side of a stage, that put out death metal for its whole life; But hardly in the world of the home enthusiast.
Case in point: Old JBL's, Klipschorns, Western Electric home audio, Altec, Bozak(? horn - don't recall), to name just a few - these are all amazing old school horns that will leave spin drift in their wake, still; that is if you can mange to wrangle them away from their owners.
Then you get into the DIY side of building and the world opens up wide with design.
Me,... I'm buying two sheets of 3/4" birch finish plywood, some piano hinges, and a couple of drivers, and building an open baffle speaker pair. I'll let Home Depot cut the wood for me, and be done with it after I cut two round holes, seal it, and mount two speakers.
Then I'll sell my Sol.speaks for a pretty penny, and pocket the rest, as the open baffles will probably set me back about $300, and about a half day effort.
When I move, I'll fold em up and take em away.
