    I have been looking for information and have come up short. Just wondering if there is a how to someplace online I could use as a reference.
    Thanks.

    Hmm, what's to know? Two drivers, one wired reverse phase to cause an on-axis diffuse soundfield due to the massive comb filtering.

    Well, yes. But I was wondering if anyone had examples I could use. What type of speakers, sizes, exct.

    Oh! Sorry, don't know of any. You said 'how to', and basically all you do is design a dual ~fullrange driver speaker with each driver on a ~7.5deg baffle and wire one reverse phase. If you want more BW and/or power handling, then add a pair of tweeters, with one wired reversed phase.

    Using the same drivers as your mains or CC seems like a good place to start.

    Vance Dickason's Loudspeaker Design Cookbook version 6 has the design for some fairly inexpensive bipoles using Audax drivers in very small boxes. Someone on another board said they sounded wonderful.

    I built the Speaker City T62 dipoles. I bought the drivers/crossovers and they gave me the outside dimensions of the cabinets, so I built them myself. I really like the triangular design and they've gotten lots of compliments.
