OK, lets have your view of the most significant Lansing inovation that transformed the transducer market. Obviously, your choice can include Altec or JBL inovations or their predessessor or related companies (Bell Labs, Western Electric, etc.).

I can't begin to list them all here but a few that come to mind might include these:

  • Cast not stamped frames
  • Alnico V magnets
  • Ceramic magnets
  • Titanium diaphrams
  • Edge wound voice coils
  • Multi-cell horns
  • Aluminum voice coils
  • Compression drivers
  • Horn loaded bass cabs
  • Bi-amped systems
  • Tangerene phase plugs
  • Foam surrounds
  • Machined pole plates
  • Du-Plex drivers (e.g., Altec 604s)
  • Phase aligned drivers
