If you own a USA Diezel Rear Loaded Cabinet and it has the insulation on the back panel - REMOVE IT. It kills the cabinet. I have owned mine for 3 years and never felt it sounded as good as it should. I also own 2 German FL cabs (one GK100 and one V30) they both kill. Today however after removing the back cover, I decided to remove the white insulation from the back panel (which my Bogner rear load v30 cab has also) and BAM! The cab has new life. A ridiculous difference in the sound of the cab now...like it had a presence adjustment for the better. From what I have read not all USA cabs had this white insulation so it may be hit or miss.
