My harddrive crashed and i lost all of my pictures
Basically, what I did was take a 1/4" thick aluminum plate (purchased from Mcmaster-carr) that was a rough 2'x14" dimension.
I used template paper when my speakers were upside down in the original styrofoam packaging (didnt want to risk destroying the tweeters) and found that the parabolic shape on the bottom of the N805 is not exactly uniform. So, I made templates for each speaker and transfered them onto the aluminum plate.
Additionally, on the bottom of the plates, I made through holes where I could screw in a bolt from the bottom and into the bottom of the speaker.
Following that, I made through holes in the center of the top of the plate which corresponded to the stand's holes so that I would bolt the aluminum onto the stand from the top, and then bolt the speaker to the aluminum from the bottom.
This was not easy because if the holes do not line up perfectly, you are in trouble. To help a little bit, I oversized the holes by about 1/16" for play room.
With all of this planned out, I tried to make a program for a milling machine to do the cut, but the milling machine was out of service. I would recommend you use a milling machine.
I had to use a band saw (big pain in the butt, busted a few blades). Then I used a grinder to get closer to the template lines. I then finished with a belt sander. Finally, I used a typical motorized rotary hand sander to clean off the surfaces and sprayed some flat black bbq grille spray paint onto it. Surprisingly, this is the only paint that I could get to stick to the aluminum without it flaking off. This was a life saver because I did not want to go and get it anodized.
Finally, I went to the arts and craft store and bought some pretty good quality felt. The felt lines the top and bottom surface to minimize vibration transfer and to not scratch anything.
Good luck and have fun! It is a lot of work, but if you are good with tools, it will be much cheaper doing it yourself than buying some contraption that almost works. If you do it yourself, and measure very carefully, it will be the perfect adaptor for your speakers without question.
