I am digging out this old thread to praise the db K300 speakers again. Tomorrow I'm playing on a wedding ceremony in a chapel, in which there is no pipe organ. I'm going to use the pair of db K300 to amplify a great Hauptwerk full pipe organ sample (which came with my Motif Garritan GPO flash library).
Just made a sound check upstairs turning the house and stairway into a cathedral... Just 11 pounds per speaker.
