Default w8-1808 in open baffle (pic)

Click the image to open in full size.

baffle is 60" tall 1/2" birch ply (free) with 2 hinges from Menard's.
Driver center is 37" off the floor (center of the tv).
Center panel is 12" wide, left panel is 15" wide, and right panel is 19" tall.

Driver has maybe 6 hours on it.

I couldn't listen to it with its boosted "presence" range (harsh anyone?).
It needed -6db at 1khz and 2khz on a 10 band eq (check out its freq graph).
http://www.parts-express.com/pdf/264-894s.pdf
I added +3db @ 30hz, 60hz, and 120hz.
I figure the open baffle Feq near 180hz, then rolls off, but no baffle step is needed.


I'll soon add a foam box around the back of the driver.
And Sunday I'll move it and play with using an 80hz f-mod with a 12" or dual 15's.

Norman

The brightness will fade. Give it a 100 hours or so.
