Getting so close . . .
All the holes are cut!!! Perfect fit on the tweeter countersink so the woofers can overlap seamlessly. FFFFFWWhheeewwwwww. Huge load off my mind. I ain't no carpenter, but I try. I must have measured five times for every routered hole.
I'll let the dust settle tonight. Tomorrow, satin poly on the unstained red oak, then, tape off the poly and flat black paint on the front baffle and back, with a dark, stone-colored formica cap. I should be able to get the drivers in tomorrow evening and back drawing power from the Sansui.
I cut a couple of shorter ports to hear what a higher tune will do. Right now, its tuned to about 24Hz for maximum cone control over the music band. You can send 50 WRMS to 20Hz and just reach Xmax. Compared to the sealed alignment, there's significantly more linear SPL available with that low tune without being boomy. The new ports will raise the tune to 32Hz. I just don't know if I want to sacrifice the low end control. The low tune gives a mid 40s F3, mid 30s F6 and a mid 20s F10. Very shallow roll off.
