List of Low Frequency Loudspeaker Drivers

Please e-mail additional data, recommendations, and corrections to me.
Changes preceeded by "|".

  This is a list of speaker drivers, many of which have been recommended by
  people on the net.  The list started out as an attempt to get
  recommendations for musical instrument speakers.  Home and car speakers
  have been added since then.  Nevertheless, the recommendations still show
  an historical bias toward musical instrument speakers.  Keep that in mind
  when selecting a driver from this list.

  Some catalogs don't list the model number; in these cases the catalog
  number is listed.  The MCM numbers are from the MCM Electronics catalog
  (www.mcmelectronics.com) [800-543-4330].  The PE numbers are from the
  Parts Express catalog (www.partsexpress.com) [800-338-0531].

  This list includes Thiele-Small parameters for many of the drivers.
  Since much of this data is supplied by readers, it would be a good idea
  to obtain specifications from the manufacturer before starting a design.

  I also have a primer on speaker systems, a list of specifications for
  "optimum" sealed and ported enclosures, and several speaker design
  programs.  See:
