Earthworks: the New Science in Microphones

David Blackmer, the brilliant engineer who in-
vented the technologies of dbx, is also the in-
ventor and founder of Earthworks. In the last 
few years of his life, David developed a num-
ber of revolutionary technologies that dramati-
cally  improve  the  quality  and  performance  of 
microphones.  In  short,  Earthworks  High  Defi-
nition Microphones™ will pick up sounds and 
details that other microphones cannot. These 
dramatic improvements are in the areas of im-
pulse  response,  diaphragm  settling  time  and 
improved  polar  pattern  technologies.  Those 
who  have  heard  Earthworks  High  Definition 

Microphones

™

  say  that  they  hear  more  attack,  more  subtle  detail  and  a 

more pristine quality in the sound than with any other microphones regard-
less of price. Since David’s death in 2002 the Earthworks engineers have 
continued to develop new innovations in microphone design such as the 
PianoMic

™

 System, FlexWand

™

 and High Definition Drum Microphones.
