    Assuming all due care is taken at the throat/adapter section how much leeway is there on the rest of the flare/contour?
    What prompts the question is the dirty great indent/decal on one side of the SAM1 and the fact I'm current shaping the flare of a H9800 plus I'm no Woody

    throat/adapter is ready!
    Midrange curves are coming. I'm currently working on it.

    Reading your thread, I feel like I've already read the novel and know how it ends...
    I won't give it away, but you'll be pretty damned happy.

    Yeah, that was funny right out of the box, all the derps on the Internet whining about how bad the low frequency response was on paper.

    The H66000 is roughly a widened H9800
    The horn sides are a bit curvier due to the form of the Everest cabinets. Look was first here.

    While using the 1500AL's reduce the system impedance to 3.8 ohms (not too bad) it also increase the sensitivity to around 100dB !! And then this LF response, can't wait to play them

    I think I too know how it ends. But still it's exiting as hell.

    I am looking for the power response measurements of the DD66000 (the on-axis/off-axis/power/directivity curves by Floyd Toole) but cannot find them (the DD66000 topic in the technical section is empty).
    Any pointer?

    Thank you Ivica, but I am looking for this kind of curves:

    I'll post full schematics when finetuned.
    Wowzers- who'd have thunk that the side-by-sides would make THAT much difference in how they excite modal behavior!

    This project is pretty costly and the parts are next to impossible to source. There are a couple other forum members working on similar systems but I don't think they are far enough along to post anything yet.

    I'm getting 98 dB SPL, 2.83V, 1m and that is with the passive filter inline.

    I can check this again. The difference can be because of different measurement systems. I learned before that mine is a bit on the high side with SPL figures. Who cares, sensitivity is high anyway.

    Thank you!
    It's a kind of rosewood which is called palisander here. My cabinet maker says that the red colour of the original Everest is a bit "tuned" by the finish. He says mine will also get a bit more red with time.
