On a completely different note, if anybody has a KEF Reference Model 90 center channel with a blown tweeter, I've discovered KEF has a replacement part number available as the KEF SP1550X "spare NT19HF unit" that runs about 30 pounds from their UK office. I need to call the US side to see if they have these and a local price on Tuesday.
I have two model 90 centers with shot tweeters (one bought that way, one from old age) so I figured it may not be uncommon.
Removal of the original tweeter is rather simple, as well.
Unscrew the 4 screws holding in the UniQ driver and remove the driver. Disconnect the 4 leads going to the speaker's terminals, then remove the single philips head screw/bolt from the center of the magnet structure in back of the 6" driver.
After removing that bolt, and the rubber gromet beneath it, you can de-solder the two thin wires (black and red) from the 4-post speaker terminal on the midrange unit.
Unpon completion of this step, simply push the tweeter module out of the midrange speaker voice coil pole location using something like a pen or screwdriver. The tweeter is simply held in place by magnetism once the single bolt in back comes out.
