The BOSE 301 Series IV speaker is a replacement for the 301 Series III and 4.2® Series II speakers. It is a passive, two-piece (mirror image stereo pair) home loudspeaker in a bookshelf configuration. The 301 Series IV is designed for use with standard amplifiers, receivers and other related home audio components. The 301 Series IV speaker utilizes separate inward and outward firing tweeters to achieve consistent stereo imaging over a broad listening area (Stereo Everywhere® performance), while maintaining a spacious sound stage. Asethetically, the 301 Series IV speaker features molded plastic right and left side caps mounted to a vinyl covered, particle board enclosure. This construction eliminates the use of edge- banding, and maintains differentation with competitors due to horizontal placement on the bookshelf. The sum of all these unique features makes the 301 Series IV speaker capable of reproducing the wide dynamic range demanded by today’s advanced recordings without strain or loss of clarity.
