Again, big thanks to @dkfreebird for dropping these off. I've looked for ages for another set to build. I'll post everything that I do to these here. Will work on these over the summer. Thoroughly listened to them bone-stock last weekend. Goal is to get them sounding as dynamic as the SDA-converted RTA-8TLs, yet WAF friendly.

First question for the hive is what speaker grill cloth is best for sound transparency in white?
I'm going to strip and shoot the cabs white with all 100% machined brass parts and fasteners.
Thanks as always.

Already started the grill frame update...

    That's a good primer.

    1.25" solid oak dowel
    cross-cut 8 3/16" offset either side puts it angled and centered between front and back weak points...

    This clears all drivers and factory crossover.
    Reason why I cannot use the larger point to point board....

    Yes, the inductor fits where the old crossover fit

    Very nice. I'll machine an adapter that mounts the Erse Super Q/factory X-over in factory location as well, mounting with 1 bolt. All other hardware will be machined solid brass, including the terminal plates, tweeter plates, and custom grill pegs.

    Thanks for the kind words :)

    really need to get the big sda inductor far away from the smaller ones for best performance

    Yet Polk put it directly behind the crossover board.

    I’m not disagreeing with you..

    I thought as long as they were in different orientations you'd be in the clear?

    Correct me if I'm wrong.
    The big C-coil or laminated Erse are different critters than the original bobbin type Polk used behind the XO.
    As far as the field they produce.

    What is the angle you cut this at? Definitely following along with your build.

    Lol I'm far from the inductor police but pools handling of the large sda inductor was... Maybe not the best.

    Mounted right behind the small inductors and mounted directly to aluminum on the big boys.

    An inductor mounted directly to aluminum will decrease in value by over 10%

    On it's side view it is a parallelogram with each long side 8 and 3/16" long.
    I started with a 8.5" length then gradually cut each end til it fit snug.

    I rasped on it this morning. (Pug Master need not comment) Rock solid now. This will translate to much improved midbass.

    No need to denigrate these further other than the factory wiring terminals were ready to short and cause havoc....
