The Model 4200 SR Dipole/Bipole Surround Speakers are purpose built for use in multi-channel audio/video sound systems as dedicated side or back surround channel speakers. The 4200 SR enclosure has two 4.5" (115mm) GLH woofers and two identical high performance silk dome tweeters as found in the 4200 LR front speakers. To further showcase the 4200 SR's flexibility, the 4200 SR can be easily switched between Dipole and Bipole operation.
Due to the switch-able Dipole/Bipole design, it's possible to place the 4200 SR almost anywhere within the rear third of the room and achieve good results. However, the best location for surround speakers is generally straight out to the sides, or slightly behind the primary listening area, approximately 1-2 feet above seated ear level, but no closer than 2 feet from the ceiling. As noted above, the surround speakers (as opposed to the back speaker(s) in a 5.1, 6.1 or 7.1 channel system, are primarily intended to re-create the ambient sounds taking place in the movie scene. Therefore, throughout most of a movie or TV program you may not be consciously aware of output from these speakers. In other words, don't worry if you aren't hearing the surround speakers. The 4200 SR's come specially marked LEFT and RIGHT, so be sure the Left side surround speaker is placed directly to the left of the prime listening area (facing the screen) and the Right speaker is directly to the right side.
For smooth cosmetic integration, the 4200 SR is available in Black, and features integral key hole mounting.
