Broke the mold today. One got a little less concrete than the other because I decided to not follow my plan :-/ Anyways, they seem usable and stability seem quite good and I feel I can lift and handle them without to much angst for breaking/cracking. With drivers glued in place - went with Sikaflex - and baffles in their cabinet - ni problem. Had to do some work to remove excess concrete in form a little lip that came from the mugs used. At 18 holes, one thing to do becomes quite tiresome :)

I feel hope.

Quick consultation please. My plan is to glue tonight...

I have listened to each driver and measured R. R came out as the picture and Left and Right has the same distribution of R. The ones with a 1 or an 9 are 7,1 ohm and 6,9 ohm. None marked are 7,0.

Row of 3 is one set of paralell drivers and the upper 3x3 will be parallel to the lower 3x3.

Top row will be placed on top in the line, followed by next row of 3 driver etc.

So a 3 group with one driver being 6,9 will show a little higher output - so how to connect for most even power distribution over the line?

There are 4 drivers per speaker out of 18 deviating from 7.0, all to the leftmost column in pic.

In reality, will it matter??

Strongest from center:

1
0
9
9
0
1

or

"Distributed - floor bias..

1
0
9
1
0
9

"Distributed" - ceiling bias

9
0
1
9
0
1

Strongest from the ends

9
0
1
1
0
9

...?
