are you doing any shading or phase shifts to focus the array?
The two center mids are in series for an 8 Ohm load, he other 6 in series for a 24 Ohm load and the two strings paralleled.
Very nice carpentry!
Too bad you don't have quite enough drivers to do the job properly.
Those line arrays should be twice as tall, you just need to cut holes in your ceiling and roof to fit them. And there should be at least four line arrays on each side of the fireplace, not just one. And you don't need a fireplace, it should be turned into a subwoofer, with at least four 18" drivers, and the chimney extended and tuned to act as a transmission line.

They should be longer, yes, ideally from floor to ceiling. In praxis it's often okay if they are 20cm shorter. They are much shorter though.
Also, you should try if they sound better with the tweeters to the middle instead to the outside (swap left and right).

They were just assembled and continuity tested today.
LOTS more cabling, XO setup and testing, and then placement and room treatment.
This step one ( cut a hole in the box ;-) ) in a long process.
No, no, they work best when the the tops touch the moon...ideally from floor to ceiling.
That gets you enough room to pack in a sufficient number of drivers, too.

And I was soo sure designing speakers wasn't rocket science..
No rockets necessary - you just climb up the towers as you build them. It's like Arthur C. Clarke's space elevator.And I was soo sure designing speakers wasn't rocket science..
(Or maybe it's more like Jack's magic beanstalk.)
I'm deeply saddened that nobody else liked my idea of the fire-place subwoofer with the chimney as a tuned transmission line.

Don't be sad! Someone's already done fire-place sub.I'm deeply saddened that nobody else liked my idea of the fire-place subwoofer with the chimney as a tuned transmission line.
I don't remember which forum.
IIRC it worked more like IB, and that's not surprising.

Replaced all the 3/4" screws with 1" waxed course thread screws and lock washers on the woofers only. See lower woofer in the picture.
This is the progress for my 4 channel test amp. Eventually it will be replaced with mono enclosures each containing 3 channels of amplification and the servo circuit for the woofers(not the Scan Speaks in the line arrays)...
