Where’s the “Signature “ bipolar speakers?

Instead of purchasing the FXI A6 dipole/ bipolar speakers, Which are, from many comment sections, wonderful. I am willing to practice some patience and wait for a “Signature series “ set of bipole surrounds. Does anyone know if they are in our near future? The merits of this design are hard to ignore and concur with it’s growing popularity. I’m not ocd but having the speakers match in my theatre rooms seems more attractive and actually make much more sense.

    It would be redundant. Your surround speakers are for ambient sounds so they don't really have to voice match the front 3.

  • Understandable. But I was wondering if Polk had floated any rumors about bipolar Signature surrounds. Thanks.

    It is a curious omission from the line, but Polk does market their smaller Signature bookshelf speakers as appropriate for surround sound duties. In practice in most home theater systems, those would function pretty much the same way as Polk's more traditional dipole/bipole surround speakers. The bipole setting on the dedicated type surround speakers is for direct sound radiation and the dipole setting is for more diffuse surround sound. It is the dipole function that is missing from the Signature line rather than bipole. When I ran a 7.1 system with LSi speakers I usually had a pair of surround speakers at the rear set in bipole and on the sides set at dipole.

    If I was running a Signature home theater system I would get four S15 speakers and run them in 7.1 mode. I would not use the older FXi line.

    I would get the FXi surrounds. As others have mentioned, marching surrounds really isn’t essential for movies.

    I have the fxi-3s as my surrounds and have the Signature 60's. I think they sound great together. It would be different if you were trying to pair them with the LSIs.
