Hardly.  Some cathedrals are designed for long reverberation times with 
unreinforced choirs and organs.  They're usually a pain for sermons, and lend 
themselves to distributed speaker systems.  Intelligibility from 
reinforcement audience members don't fully distinguish from direct sound is 
the goal.

Simply deadening things as your other post suggests can be a poor solution, 
depending on other factors.  Controlling live and dead surfaces is complex 
enough it's not a good do it yourself job, though substantial consulting and 
treatment addressing those issues can get expensive fast if qualified 
engineering services are used.  That leaves considering work arounds, as 
suggested in my previous message.  The sharper band amp is a poor solution.
