One pair of Newton Series S300 surround speakers, white. 3 way switch for Dipole, Bipole and Monopole and instructions. Will only sell as a pair. Ad will be removed when sold. 3-way, 4-driver surround speaker, the S300's Multi-Mode implementation offers three dispersion patterns for optimum performance with any surround sound program material. The Dipole mode provides a diffuse dispersion pattern that seems to be coming from all directions. Diffuse dispersion is favored for Dolby Surround recordings. The Bipole mode retains the broad dispersion of the Dipole mode, but adds a center focus ideal for synthesized surround applications (e.g. DSP hall or stadium modes) and many Dolby Digital recordings. Direct (monopole) mode employs a front panel-mounted two-way system of superb fidelity for precise rear speaker imaging on programs featuring a larger amount of complex rear channel sound (like many DTS or Dolby Digital concert recordings and soon-to-be-available DVD-Audio recordings).
