HTML Style Sheet RCA LC-1A (MI-11411-A) Coaxial 15in Alnico Speaker - 15 Ohms Description An impressive design from the esteemed Harry Olson and RCA, the RCA LC-1A is a 15 inch Duo-Cone 2-way design utilizing an ALNICO magnet structure. There are many special features within this design.
  • A specially-shaped curvilinear special-pulp paper cone; The internal damping in the pulp of the bass cone helps to ensure a smooth frequency response. The congfiguration of the very shallow curvelinear cone influences the high frequency response and directivity.
  • A dense foam-rubber dampening ring fitted in the corrugated surround; Damps unwanted resonances and absorbs out-of-phase information and prevents its reflection back to the voice-coil.
  • Conical deflectors reduce the velocity of wave propogation in the large cone, this broadens the directivity pattern. Decrease the angle into which high frequency waves from the tweeter feed, thereby increasing the output of the tweeter. Diffract sound from the tweeter, thereby broadening the directivity pattern.
  • A 'butterfly' tweeter attachment deflects the tweeter output in order to broaden the directivity pattern.
  • The mounting brackets on the frame (the ears) are stepped back to allow the speaker to be flush-mounted with the baffle from the rear. This eliminates the well-known cavity effect, which makes for a " hollow, chesty sound ".
