Alex's file is an xml style Excel file. If Dust is using Excel pre-2007 (I think that's when MS adopted the xml file structure) he won't be able to open it. Alex, try saving it as a 2003 style Excel file type (in the Save As dialog). Extension should just be .xls, not .xlsx. I use OpenOffice so I'm not sure how robust it will be for me to do the conversion (but I've attached a file I tried it with in case). Dust, try my file. If that doesn't work, Alex should convert it and upload again.

Thanks Carl.

I normally save excel stuff as .xls when sharing but my enthusiasm got the better of me.

Don't be concerned about the 32 block sets shown in Alex's pic. The missing four sets would have to bridge across the corners and are not really required. You can add them or not.

The number of blocks were originally chosen due to the ease with which polar graph paper (long before personal computers were available) provides convenient divisions based upon 360 degrees. As it turned out, this number was the correct choice as gross changes do provide interesting, but not entirely useful changes to the phase response across the 1k and up FR band.

Another Planet10 design, MK70mt, el70 driver in a western cedar enclosure.

why is the enabling pattern found on the frame of the driver? Certainly by being bolted to the cabinet, this produces no effect other than an aesthetic one right?

One of the sets done to evaluate whether is does make a difference.

Oh cool! I can't wait for the feedback!

Any theories as to how it could?

likely none that will find consensus

One person, by definition, must come to his own consensus. THAT is what I am interested in. Not a, go nowhere, "discussion".

For example, ANY design decision I make will have a reason. And even if that reason is aesthetic, or even random, or guesswork, I will admit to it. I would LOVE for someone to admit that they enabled the frame of their driver because they think it looks cool. But, whatever the reason, I want to hear it.
