I simply covered the boomer with a thick paperboard and a textile to lay confortable and warm while working. Note the tweeter is oriented directly to my head direction by placed quite far. be carefull : you might want to feel the hit of music vibration as strong as possible but it may vary a lot depending what instrument you are using so preferably make tests before covering the speaker with your loudest percussions and sub-bass waves (some bass are "painfull" for the speaker but are almost unhearable especially under 50 HZ ).
I highly recommend the use of this furniture for deaf DJ's
