Horn speakers are really bright?

horns can be bright, any type of speaker can be bright if not properly impemented. The example of Khorns with a Crown DC300A is a perfect example of how NOT to implement them. 

The idea that horns are always bright as some have opined is ridiculous. Check out my system.. nothing bright about it

Some people may have bright rooms.

Herman,

Isn't the sound affected by the large objects sitting in the bass horns?
