These are finally  all  finished up  now so  a few final pics, possibly some ideas for folks who are  building   these from  packs or who want   finished cabs.
Here you  can see  we  mounted both the tube connectors as well as  a female Speekon conector for the subs at the rear  edge of the  side panels.   On the inside  , I peeled back the foam  of the norez so the wiring  could  be  tucked away nice and neat. After wiring, some spray adhesive  sticks the  foam down  and it's all hidden away.

Crossovers are built on some  3/8" Medex and painted with   bed liner to match the  Duratex'd  rear sub cabinets.  We glued a sheet of 1/4"  Sorbathane to the botom of each board and trimmed  to  match the boards. We used  Clarity CMR caps for  the high pas filter bypassed with  Milflex Cu and  a Gortz Alpha Core  foil inductor.
Low pass   filter consists of a  Gortz Alpha Core  foil inductor  and a soniccap G1 bypased with the  Milflex Cu.  The notch  filter was left as is.
Wiring from  the tube connectors  to the  networks and then on to the drivers is all Neotech UPOCC solid 16 in Teflon.  The input wires to the networks  come up  through the top of the  rear sub cabinet and  enter through the bottom of the c/o board right at the   high pass cap and low pass inductor..  Boards are secured via  4  hex driver screws ( had some kicking around for the  SW12's)

Found some cool little wiring clips on Amazon to route  wiring up  right against the  wing. they  come with  some  3M PSA on the back of each one so easy to install.   I could only  use them  on the tweeter  and top 2 Neo10's, they were a  touch small  for fitting the  entire bundle in the  lower  Neo10's.  Need to find  some larger  ones  for those

All the Neo10 screw holes were  tapped (M3.5 non-bottoming tap) before mounting  each Neo10 & gasket  with some hex drive M3.5 x 12mmmachine screws

The amp boxes were wrapped in some Tamo Ash veneer to match   a custom  Uber bus  from Dave over  at  PI Audio.  the boxes are also fitted with femaile  Speekon Connectors.  A patch cable  was made for  each  speaker with a male Speekon Connector on each  end , you can see it above in the first  pic.  The boxes  were finished in danish oil topped with Satin Arm R Seal

We finally  got to the grills, well ,  Don did.   He  got the hang of it  pretty   quick, he's even got the  rear  side  nice  and neat. He cut the cloth  slightly oversized then  sprayed the entire  rear side of the grill frame with  spray adhesive.  Stick the cloth  all the way down  one side before  stretching it across the front  and  up  and over the other  edge.  Once the  2 sides  were  stuck,  he repeated for the  ends.    trim the excess  from the corners with a sharp  razor  and then work the  corners until  you  get them tight with no bunching.  Last but not least,  trim  all the way around the inside edge of the   grill frame with  the  razor.

The  6 N52 3/8 x 3/8 cylinder magnets  do a great  job of holding them in place... in fact,  you  need to be a little careful when removing them  as   you  don't  want to snap  a grill frame !

And  one without the grills

And yes, I know.. promised a  bit of a write up   in regards to the S7's  / Otica's....keep meaing to do  it ....
