    I learned that - a little late!!!

    Interesting!

    They don't sound too shoddy actually - a little strong in the midrange.
    I'll hook them up to my Quad 306 next week...

    A forward mid makes them even better candidates for an omni type application. It may sound daft, but as an experiment, lay them on their backs with the tweeter angled so they aim towards the real wall and have a listen.

    Thought the results might be interesting. The imaging will be diffuse, but that can be pleasant. You will still get a stereo image though, but a large one.

    Another thought. Car speakers are usually well magnetically damped, enabling them to be used in all sorts of 'ill terminated' mounting positions. This means that they should respond well to reflex loading. In other words, a well chosen bass port should beef up the bass nicely.

    This is fun!
    I might hole saw a port - the 'well chosen' is the toughie though!!!

    length of port may be more important than size of hole. you can buy variable tubes that you can play around with

    You need to know the fundamental resonance of the driver and the cabinet volume.

    I doubt you'll find info on the driver, but you might, T/S parameters would be handy. I can have a stab at a guesstimate if you like. What's the outside diameter of the driver? There'll be a port calculator somewhere. I have a set of ancient but very appropriate G A Briggs tables knocking about.
