Horn tweeters: do they need a cabinet? So why not just a frame to hold them in place?

I see a lot of people who use compression drivers in horns that make a cabinet for that horn. I can understand that for live use (to protect) but for hifi why would you make a cabinet for a horn, why not just put it on top of a bass cabinet or use it in a frame to hold it in place (and right angle to the woofer).

I know some do it, but i want to hear arguments pro and contra. Why would this be a good or bad id.
 
In fixed installations, there is no need for a box as well (EAW CB152 cinema speaker)

A horn as it stands is not necessarily a complete flare/baffle arrangement. Best would be to analyse it's effect and decide for yourself if it meets criteria. Not only might extending it at the end make an improvement, the way it's extended is a factor.

If the flare on the horn is complete (most are), they can be suspended with wires. You do want them to remain fixed in space, but aside from that, no need.

I've seen and used horns for decades on brackets only. Mounting in a box is only a convenience. Keeps consumers from damaging them or connections as MrKlinky mentioned.
