How to kill 2 birds with 1 stone

THATS MY PROBLEM. I'M LOOKING FOR A PAIR OF FULL RANGE SPEAKERS, PREFERABLY, ONES THAT COULD BE WALL MOUNTED, THAT WORK WELL FOR LIVE MUSIC REPRODUCTION (PA MAINS), AS WELL AS RECORDED MUSICAL REPRODUCTION. SPEAKERS SHOULD BE ABLE TO HANDLE ALL TYPES OF MUSIC, SOUND GOOD AT HIGH AND LOW DBS. ROOM IS APPROX. 20X50FT. THANKS FOR ALL RESPONSES, THOUGHTS AND SUGGESTIONS!
