Why don't you try taping a couple of sheets of toilet paper over the tweeters. You would probably not believe how many records were recorded with Yamaha NS10m speakers with toilet paper over the tweeters. Google it and you'll see. If you use grills it doesn't matter, but even if you don't, you can probably do a nice enough job that you won't mind looking at it.
PS - you should have bought the Doge6 instead of that ARC, but you got caught up in the name-recognition thing.
