Building FAST, did some CBTs - ended up in FAs
From an attempt to build a line source out of 2" fullranges, well almost, I got a couple speakers left over:
Yes, it is Jordan/EAD E60.
Edit:
As it turned out, it ended up in CBTs using the same building practice.
Edit one more time:
Dramatic turn of events; now it´s FAs using the same building practice.

So what to do? I wanted a quick evaluation of the speakers as they are meant to be used.
Had some aluminium profiles laying around:
Cut one of them in four, thus making them 25 cm each:

them drivers are expensive . 32 of them in the piccy.. now if i was going to spend that much on drivers i would make sure i knew exactly i was doing first not buy them and then learn lol..
With 13 cm deepth, 9 cm width and 25 cm height, it ended up with a volume of 3 liters.
And that just about two times the Vas of one element.
With all the pieces cut out:
Let´s start assembling.

Sides:
Back and first front piece:
Bottom (and top):
Any mismatch that will result in leakage is covered with silicone rubber, on the inside for front and top and from the outside for the bottom.
To make the bottom easily detachable adhesive tape can be used instead.

Mount two elements in the back and you got dipole or bipole.
Mount elements on all sides and you got an omnipole.
Mount four in a row, repeat the above.
Replace the MDF with some arctic birch plywood, plastic in any color or even glass.
Make them with black profiles.
The possibilities are endless.

Nope, they will end up as home theater satelite speakers, computer speakers, kitchen speakers...
Actully, I took no risk. This is plan B from the beginning.
And I knew that they could be resold at a low loss, having bought that many.
So how do they sound in this configuration?
In fact, excellent.
Even with only one side built, it fills the room with a soundstage matching that of my full range ribbons.
I will measure them to see if they need any EQ and to figure out if the elements are at their optimum distance.

Ingenious!
Is that a standard extrusion? If so, what is it originally meant for?
I might try and get some locally - could be good fun!

Yes, it is standard extrusion (thank you for that word).
I got it from my local Bauhaus shop. There's even corner pieces and other specials.
It is normally used to build utility boxes.
