    Open Baffle Design

    Hey all, I have several sets of dual concentric and point source drivers I've tested and played with over the years and want to try to build an open baffle for them to use in my listening space.
    Has anyone ever done this?
    Are there any tricks or secrets I should know about?
    Ive got the following drivers to use
    Tannoy 6"
    Tannoy 8"
    TB W8's
    Dayton PS220's
    Any help would be greatly appreciated

    I haven’t done them but have heard several at shows and read extensively about them. The one thing you’ll need is cone area and a relatively clean/uncluttered room for them to sound their best. Cone area because they don’t make as much midbass/bass as an enclosed driver and an uncluttered room so you don’t get a lot of waves bouncing around or you’ll get quite a bit of cancelation down low. For the midbass side, I’d try using multiple 8” speakers or step up to a 12” or even 15” midbass. The speakers I heard had dedicated high frequency drivers but I don’t see why you couldn’t build an open-baffle line array.

    So what Id like to try is a single driver on a baffle to start then maybe expand to multiple drivers on a baffle if this works in the room.
    I have a 12Ē sub that will cover the lower octaves so if I can get down to 100hz that would be optimum I think. I know the Tannoyís will do it easily itís just making the proper baffle for it.
