    Looking for a list of surround speakers that allow you to manual or remotely switch the speaker from monopole to dipole and vise versa for different applications. The debate is ongoing about the use of monopole vs. dipoles for movies and music, and it would be nice to have the choice between both rather than deciding betweeen a strictly monopole or dipole speaker for a set of surround speakers(either side or rear) as opinions and surround formats change in the future. Thanks for any contributions to this list.

    I know M&K also sell a TriPole speaker.
    But you really want to avoid these "gimick" speakers.
    Here is the problem: even if they worked as well as they claimed, you need to:
    - Mount them differently for each style
    - Calibrate with different numbers for each style
    Dipole - you mount these to fire along a wall so the listener only hears indirect sound. They often need to be turned up louder to mate with the front speakers.
    Bipolar - these should be mounted 2-3 feet into the room to give the rear-fire sound some time delay. These are a direct-radiator so they often dont need the extra volume of a dipole.
    Direct/Monoploe - These are the simplest to setup and use, and minimize the use of nearby walls. Dont forget that you want to allow for 3 of these: one for that rear-center speaker. And this is the type of speaker many studios assume you have, including all the new audio formats like SACD/DVD Audio.
    So the complexity of correctly using each make it more trouble to flip that switch than it is worth IMHO.

    They are pretty expensive, but both Aerial Acoustics and Revel make surrounds that can switch between bi/di/mono. The Aerials have a remote control and I think the revels can be switched either manually or with a 12v trigger.

    Also, Cambridge Soundworks S-300 is Bi/Di/Mono switchable.

    Take a look at the Von Schweikert Audio Tripole TS 350. Comparable to the Aerial at a reasonable price!
