Hi, I am new here, so pardon me if I'm asking in the wrong place, or the wrong way. I have a pair of ancient, not exactly matching stage monitors which contain E-120 drivers with the old 4706 bullet tweeters. I would love to have the box dimensions and porting information to turn them into the great wedges I suspect they can be. They are impressive sounding as they are, but are very bulky and one has a volume control, the other does not, and I'm sure the boxes are home made. I would appreciate any info you may have.
