Looks like those will need the spacer/washer behind the tweeter screws so the faceplace isn't distorted. I love my 5B's.
These were the burnt set I got from VSAT and rebuilt with aftermarket silk domes. These frames have been butyl-matted on the back sides. I believe that once they have been torqued down at the mount screws, those indentions are there to stay.
P.S. can someone please explain to Vanilla that I meant to say indentions, not intentions. Damn computers are getting dumber by the day.
I thought those tweeters looked familiar. lol. it took me another set of tweeters before I found the problem that toasted those. The B&K amp was oscillating at random times due to of all things a cold solder joint on one of the power supply boards. That is all fixed now and then some. I had a set of those speakers too. I liked them but someone else liked them much better than I. I cant believe how nice those are looking. Great job brother. I will stay tuned.
Oh, one more thing. No new real wood veneer for those ? Sure would look nice.
I'm on the fence between a light wrinkle-black to match the factory baffle face material or go with Benjamin Moore's new Molten Metal series (It's trick)
The wrinkle-black looks great against the billet aluminum pieces going into the build.
You can believe it or not but I have used satin rattle can spray paint to very good effect. Using the instructions it really did come out nice with the sanding and all. Please don't ask me where I got it because it is black and we will all be back on the longest thread in Club Polk history about "where do I get black paint" again ! :-)

The billet RD0- tweeter project is finalized...I'll do the capacitor burn-in this week while I decide on what type of black finish to finalize the cabinets. Anybody else have this dilemma?
Also I used solid sheet 0.085" PVA foam to make new gaskets....
Sounds like a nice thickness. I might've gone thinner. I'm not sure what Polk used (or what its uncompressed thickness was) but it always seemed to me like it might be a polyethylene foam because it reminds me of the feel of the light grey pipe insulation (not the armacell). Where'd you obtain that PVA foam?

The way you have those speakers bolted in there you could use just about anything and it would compress enough to seal them off. Very nice work @xschop .

I needed only 3 sheets from Hobby Lobby, as this is one of the standard stocked thicknesses.
I spent all my time at the pool this weekend to have any real listening time, but caps are being burned in at the moment. So far, they sound crystal clear and balanced.
