I need some help...please.

I'm trying to change crossovers in my 1801's (actually, trying different resistor values) and can't get one of the tweeters out of the cabinet. It seems as if the wood has swelled to a point that the tweeter is stuck in the cutout hole. I have tried pushing on the back of the tweeter with my arm through the woofer hole, prying it (gently) with a very fine screwdriver head, and lightly tapping it on the back with my hand (last ditch effort) all to no avail. The speaker is not sitting on my hallway floor where I hope the cool floor will cause the wood to slightly contract, allowing me to remove the tweeter.

This thing is totally stuck in the speaker and will not budge one millimeter. Any suggestions will be greatly appreciated.

Thanks,
Jack

The cabinetmaker has cut the relief tight, happens to us a lot. Remove the screws and use a dentist's pick or other hard steel bent-tip instrument to go in throught the screwholes. Even a narrow blade screwdriver should word. Use the tool to pry the tweeter flange away from the wood. Once you break the seal the tweeter should come out easily.

I gather you are trying to change the tweeter level? There are things called pots for this...

Thanks Brian. I'm actually testing some different crossovers in my 1801's. So far, I like the originals which are a completely different design than the ones I currently have in the speakers. It seems that more than the tweeter level has been effected by the changes to the crossover. I'm messing around with a couple resistors to try to dial things up a notch.

I have tried a screwdriver and an icepick in the tweeter screw holes but this thing is tight. The Hiquaphon (SP?) tweeters require you to solder the pos and neg leads into the back of the tweeter so removal of the tweeter is essential for crossover changes. I will try your suggestion but this tweeter is really stuck. I don't want to break anything but it's going to take some real tugging to get this out!

THanks again!

Have you tried smashing the cabinet with a hammer then gluing it back together? Another method is to incinerate the cabinet. This is more difficult because you run the risk of burning the drivers

On a serious note, try using a rubber glove, reaching into the cabniet (by taking out the woofer) and twisting the driver left and right.

DRILL OUT THE CENTER OF THE TWEETER, then go to a local body shop and ask to use a dent puller, buy a new tweeter, done .

have you tried freezing it then pushing out from the back

Dave Ellis gave me a couple good recommendations. I'll try them and let you know which one works. His tollerances are very tight on the tweeters and the wood tends to swell with moisture. Not usually a problem but it is at the moment. I'm confident one of these suggestions will work.

Since the cabinet's are swelling because of moisture, you can just send the speakers out to Denver, it's so dry here the swelling will go down.

Good luck with the crossovers.
