Dayton Audio DC28F-8 1-1/8" Silk Dome Tweeter
Is this tweeter magnetically shielded? It dosen't really say so.
No, this tweeter isn't, however, the Dayton DC28FS-8 (part number 275-075) is exactly the same as this tweeter except that it IS shielded. Good luck!

Flush mount? Can the flange be trimmed?
I'm trying to replace the ruined drivers in an old Allison CD-6 cube. The original tweeters were flush with the cabinet face. Should this tweeter be mounted so that the top of the flange is flush with the cabinet? The originals were exactly 4" dia. Can I trim the flange on this down without ruining it, or am I better off expanding the diameter of the recess on the cabinet?
This Dayton Audio DC28F-8 1-1/8" Silk Dome Tweeteris an amazing tweeter. I have used it several times in various installations. I have removed various amounts of it's flange to accomodate existing hole needs without changing the sound. I have also cut a slit an a length of automotive heater hose and slid the hose around the flange to provide a gasketed shock mount.I have also used it in new installs where I routed the opening and recessed into the baffle board. My point is that it has always been versitale and quality. So long as you do not modify into the working portion of the speaker and only trim the flange you will be fine.I think that there perhaps may be some minor change in the sound if material is removed, but I have never noticed a difference in a system. I would suspect that in order to actually hear a difference the entire system would need to be under good testing conditions and pro audio analysis equipment.Good Luck

What is the outer diameter of the tweeter (is it 4 5/16?) and the sitance between the screwholes?
I just want to make sure they will fit.
The outer diameter is 4 3/8 inches (so you were close enough) and the center of each screw hole is exactly 1/4 inch from the outer edge of the speaker.

Can you clean the silk dome?
I just built the BR-1S kit and during the process got sawdust all over the tweeter dome itself. The dome seems to be sticky and I didn't want to damage it by scraping the sawdust off. Any suggestions? Is there a liquid I could use to gently wipe on it without hurting the dome?
Hmm toughy. You could try alcohol but nothing more stronget than that. Spray alcohol on and blow the particals off with Dust-chaser. You never want to touch the dome.WE learn these things by doing: dont take the drivers out of thier boxes until you are ready to mount them.

Cutout Diameter Clarification
Stated cutout diameter is 3-1/8 inches. Does this include space needed for the terminals, or is there some additional material needed to be removed to enclose the terminals?My existing tweeters in old KLH Model Cl-4s are 2-7/8 in diameter for the body with a "notch" for the terminals, so I would have to enlarge the hole it appears. They are 1-in VCs if I am not mistaken.
YOU WILL NEED TO CUT A NOTCH FOR THE TERMINALS...IT SHOULD BE ABOUT 1/4'' X 1-1/8''. IF YOU USE FEMALE SPADE CONNECTORS THEY WILL FIT IN JUST FINE. BY THE WAY THIS TWEETER IS ONE OF THE BEST AROUND!

Recommended crossover frequency in a two-way system
I'm planning a first order crossover at 2,000 hz, to be used in conjunction with a GRS 10PR-8 10" woofer, 35 -3,000 hz. Is the tweeter okay at 2,000, or better at a higher x-o frequency? How high is too high for the woofer?
The tweeter is good to about 2500 hz with a first order crossover. Your 10" is not really a good match though... Here's a simple cheat... If you want to do a speaker with a 6db crossover... If a driver is spec'd from 500 - 5000 hz... then it's usable range is 1000 - 2500... Half the numbers... So your tweeter has a low end of 1300, so 2500 is safe. Your woofer choice however has a high end of 3000, so 2500 is too high for it to operate musically. Also - from about 500 - 800 you're in the critical mid-bass and you want the best sound from this range... Maybe a three way? Or a great two way with a 6" driver and separate sub?
