Making some of these components work in a home environment will be very difficult. The 4" compression drivers and the associated horns are really made for very large spaces like a movie theater sized room. They will sound very overbearing and probably harsh in a home sized room.

I use horn theater speakers in my system, but they have 2" drivers and smaller exponential horns.

The "wedge" speakers are used in cinemas for surrounds, and would work pretty well in if you have a large room in your home. I use the smaller version of these myself for surrounds (8330).

You can always experiment with them, and if you like the sound, that is all that matters. You will probably be better served by some speakers made specifically for home use......unless you have lots of time and love to tinker.
