    hey guys, sorry, I don't know where to post this question.

    I've got some few questions
    1. What is soundstage?
    2. What is the difference between bipole and dipole speakers?

    Thanks.

    soundstage - the stereo image of the music as how your brain percieves it. its best if your speakers are calibrated and equidistant from listening position of course. Listen to Pink Floyd's Brain Damage, sounds will pan left and right and all over the place. close your eyes and start pointing where the sounds come from. theoretically the area between the speakers is the soundstage, but when you start to hear ppl talk about their speakers being 'invisible' they mean that the sound stage doesnt stop at the speakers, or in other words, when you close your eyes, you cant pinpoint your speakers but you can pinpoint sounds coming from them.

    Yup. And speakers that have a larger or "better" perceived soundstage can be placed further apart from each other and still mantain a pretty seamless left to right transition. Speakers that are too directional would leave a large gap in the middle. If you have a good soundstage, you can obviously differentiate between the left and right channels, but your brain should also sense sound coming from the middle as well.

    1) The soundstage, was roughly described above, but when you close your eyes listening to a really good setup, you can place instruments and elements of the sound left to right, and their sizes, and also very important, their depth front-to-back. Sometimes you can also hear some slight spacing top to bottom, but the major elements of the "soundstage" is how "large" it is in relation to the speakers, how tightly things are imaged within that space, and where they are placed in that "stage."

    If you listen to a really good setup, turn off the lights and close your eyes while listening to some well-recorded natural jazz and such, and you can hear the space of the recording location, and where things are placed in it. A good natural test is the Buena Vista social club, very big space, you can hear all sorts of things in that. Orchestral is also usually pretty good, though IMO more difficult to do right. If you get a chance to hear a really good setup, listen for these things, and try to hear what your setup sounds like too.

    Oh yeah, I forgot to answer #2 :b

    2)bipole: has speaker drivers on opposing sides of the speaker enclosure operating in-phase. So, when one pushes out of the box(creating + pressure), the other does too. So they sort of "work together" though if you think in absolute space, they are moving in opposite directions.

    Dipole: same configuration, but this time out of phase, so when one moves out, creating + pressure, the other moves in creating - pressure. You can visualize this as them both moving in tandem, but on opposite sides of the box again. Dipole would create a null(moreso with the bass) on the axis between the drivers. Dipoles are morecommon in surrounds, since the are placed beside the listener, with the drivers pointed front and rear usually, which points the null at the listener, so very little sound is reaching the listening position directly from the speaker, but rather from the room creating a larger sense of ambience.

    Something like a electrostatic panel speaker by nature would be a dipolar speaker.

    Hey,

    Thanks for everyone who responded. So if you were to choose for surround speakers, bipole or dipole?

    Did I miss any other type of speaker other than bipole or dipole?

    Thanks again.

    Neil

    YES, you did. normal monopole or direct radiating speakers. and that's my recommendation for surround speakers. good ol', plain ol' speakers.
