which sounder will be louder?

hi guys. I have a texecom oddysey 3 (twin piezo version) and an elmdene prima 200. which one is louder?. I can't decide which one to fit they both look good.

from your experience what would you say.thanks

ps; i will respond to your replies. I know you have had id..ts on this site who never bother to reply to your answers which ruins it for the rest of us who genuinly need help.

any advice would be deeply appreciated thanks :)
