    Thanks looks very similar but not identical to http://www.allaudioexpo.com/nav/details.asp?itemid=306 . Maybe I should order both and try to create a cad model for future reference.


    Is there any further information on the Jeff Bagby revolution?

    I buy it, if it places the woofer acoustically closer to the listening position.

    Is the Manocor waveguide the same as http://www.allaudioexpo.com/nav/details.asp?itemid=306 ?
    https://www.soundlabsgroup.com.au/p/...300+Wave+Guide is pretty expensive, but it's the only US retailer I can find.

    Wow this is a great thread, I was also looking to replicate the s400 and amphion design aesthetics. Personally I read the reason for mounting the tweeter below and the 2 degree tilt, but I don't buy it. The amphion has a similar aesthetic with the more conventional top mount which I prefer and will try to have a go at. I'm also happy to collaborate and contribute to the effort.

    Reigningchamp,

    I am also doing an S400 clone. Using this waveguide: check out this link, several dome tweeter / WG tests. I'm going to use this WG:

    https://www.monacor.com/products/com...gy/diy/wg-300/

    I'm not sure about the tweeter yet: maybe the D2604 or the Vifa DX25, or any number of SB tweeters.

    I already have the SB17NAC woofers burning a hole in my pocket.

    I'll be happy to collaborate with you on the project.

    Cheers,

    Greg

    Revolutions use the sb15 satori.

    Nope, you've gotta do that.

    Note: When you tell ISD that you want a vented box (for example), IT gives you its "best guess" recommendation, based on Qts, Fs, and Vas. That's its best guess as it pertains to interior box volume AND Fb (tuning freq. - which ultimately (along w/the box size and those 3 T/S parms) establishes F3). However; (AFAIK) it ALWAYS defaults to a 4.02" id port tube (which in metric is 102mm ??). That is NOT its recommended port diameter (which would be ridiculous for any driver smaller than 8")! It just defaults to it. It doesn't KNOW what dia. you'll ultimately use (and even if it did know the I.D., it wouldn't know the wall thickness - hence the O.D.) so it can't really calc. the volume used up by your port. Also, you COULD mount the entire port external to the box, right? So... just too many variables for it to take a wild guess. YOU have to make the wild guess.

    Thanks for the replies guys, guess I was just misreading the WINISD output. Eagle, fpitas, I’ll have a look for it, Jeff’s name carries some weight in the diy space so Ill consider his as well. Might go with a pair of Rival R176-CW6’s I have on hand instead and maybe the new sb ceramic cone tweeters. A quick question regarding ports in winisd: is the response graph given calculated with the volume loss of the port factored in?

    Check your volume "units" (liters vs cu.ft. makes a BIG diff. - like 28X!).

    That's very good advice. Jeff makes nice speakers, and unless you want to learn how to design (good) crossovers, that saves you the effort.

    They look easy enough to replicate. You'll need a suitable waveguide for the tweeter, and you'll need a suitable crossover to flatten the tweeter response, to take care of the rise near 1kHz caused by the waveguide.
