Horn based loudspeakers why the controversy?

larryi practical isn't what audiophiles or audiophiles system are about. Many front horns can be placed near wall or corners so take up less usable room sqft than standard audiophile fare of monitors on stands pulled out into room. My giant community leviathans use up the same space as my slim fostex towers did.  Many OB designs would require more usable room sqft than front horns since it requires distance from rear wall and proper baffle size to produce useful low frequency most greatly undersized and under-build  OB designs and look at it as a quick easy fix when in reality they are anything but. A OB needs to be greatly overbuilt or they become sound boards much energy wraps around baffle edges you can easily feel it when music is played. Also drivers in OB designs rock baffles with cone movements most OB I see do not address this and many place tweeters and mid on such unstable baffles. Not saying OB or hybrids are not viable or that one can not get good sound out of its just sub-optimal when used with horns.

Siegfried Linkwitz is the guy out there making foolishness out of all the "narrow dispersion is good" silliness. Maybe it's good in a PA, but not a living room. This crowd here deliberately avoids and ignores anything that disagrees with their OPINIONS. That's the source of this controversy. 

https://www.youtube.com/watch?v=rrxwudn7C4w&t=2327s Siegfried Linkwitz is complaining about conventional designs and he even is holding up a model of a conventional ported monitor complaining about its design one would have to be daft to think he is ripping on horn tech I would suggest if he gives this link so much regard he should buy one of his madisound kits. phusis said earlier {In essence: the controversy surrounding "horns," as I see it, has more to do with misinformation, confusion of definition, convenience and habitual bias than any actual assessment of a pair of true horn speakers} if the shoe fits.

You missed all that jazz about acoustic centers, edge diffraction, and directionality? If you're listening to a pair of Klipsch, you're listening to a speaker that incorporates every failing he points out.
