Horn - install in cabinet or not?


I'm planning to build 4-PI pro speakers. I've been advised by one cabinet maker that it is better to build with the horn outside the box, placed freely on top of the cabinet. The idea is to offer some freedom to move it a bit with respect to the woofer cabinet.

My experience with speakers is that small toe-in adjustments do matter, but I've never fooled around with doing it with separate drivers. Could folks with experience here comment whether this is the way to enlightenment or madness?

Thanks in advance,

- Ken
