I've got a DRRI, and it suffers from the typical DRRI issue being super bright at low volumes. I've replaced the tubes with JJ's which made it sound better. Currently I have a Weber Alnico in. I haven't clipped the bright cap yet, because I'm a little nervous to completely rip it apart. But I was wondering, what would be a good speaker to darken it up a bit, preferably something that a quieter speaker, as I can only get the volume up to between 2 and 3.
