Default Another exotic Japanese fullrange (defunct Exact brand)

Yes, this is a DIY project . . .

The enclosure (17 liters volume) is made from MDF, although a prototype shown below is in plywood.

The driver is a 12cm driver from the defunct Exact brand. Having heard both, I think these drivers are not as nice as the Feastrex drivers, but they are pretty nice. I love the looks of the enclosure. The ports are on the bottom of the enclosure.

That's all the information I have, unfortunately.

Pat the wet paint with a scrunched up plastic shopping bag.

Very hard to get it consistent. I've never been brave enough to try it.

What people won't do for a nice paint finish...

My girlfriend is an artist-painter, she uses most of the time an dry primed underground and then starts to pour oilbased paint on them in different layers, then a water based paint.

What you'll get is a "water" motiv on the canvas, something I like to try someday.... But the rist of failure is high, and the cost (in time) to repair is great.

I wonder why the Company choose to use square magnet cover assembly for their Exact driver. Doesn't seem to add any benefit. Maybe it was easier to manufacture then a circular cover.

What magnet type did Exact use?

Yes, that particular model used a rectangular yoke because it's cheaper. You'll note too that the frame is stamped steel. The magnet is alnico 5-7, and it is quite a beefy one for a 12cm fullrange driver -- although not as large as even the smallest magnet that Feastrex uses.

I am most impressed by the use of that lens. I think those are under appreciated and I love to hear one used like this.
Thanks!

That acoustic lens is definitely DIYable. The fins are made of bent plastic. They are inserted into slits cut into strips of wood, and they have tiny foam rubber spacers to keep them properly aligned. They could be held in place either with velcro or with embedded rare earth magnets.
