Down to the Nitty Gritty
Well, last night after my hangover backed off enough that I did not feel like I had a hatchet stuck in my head and a stomach full of rattlesnakes, I decided to go play with the Cerwins some more.
I first checked out the woofer that I had noticed coming un-bonded. I wanted to make sure there were no other problems before I ordered the glue. That's when I noticed a small crack in the surround. I pushed it a little with my finger and MUSH.:sigh:
So, I now have to re-foam these suckers. I thought, "The money is starting to add up, but at least this is an easy and readily available fix." And it is. I went ahead and tore some off to relieve a little stress.
I started thinking about everything I need to do. This Cerwin project is a side project I am doing. My main project is finishing those cabinets and moving in my pinball machines. So, I have been working on these speakers a little at a time between working on my cabinets, and my mind is not 100% thinking clearly while I sort these speakers out. I had already mis-taken rotted foam surrounds as just a little glue coming loose.
What else did I miss???:headscrat
I decided to look back at the speaker I had tested the other night, the one where I found the mid overpowered everything else and really needed the attenuator to balance it out. This speaker still had the drivers in the cabinet. I had not tested these drivers with the meter, I just hooked the rigged crossover in expecting the drivers to be fine, and if not I would surely hear it. Well, I did not hear it. I mean I heard it alright, but I mistook the
TWO BURNT OUT DRIVERS as the need for attenuators. :twak:
I thought, "Bet these burnt out drivers are sure gonna be hard to find Wally."
And they are.
I am still going to fix the attenuators, but now I have more parts to find and more money to spend.:tears:
Here is the diaphragm I need to fix the burnt out tweeter. It is a Heppner/ Cerwin/Klipsch part. I found some black ones on Simply Speakers, but they do not look to be the same material as this tan stuff.

If anyone knows of a source for the original, please chime in. It is 8 ohms (when it is not burnt out)
Here is the horn diaphragm that is burnt out. They look identical to each other
except the horn is 16 ohm. (when not burnt). I have not gound these anywhere.
Oh well, here is my to do list.
1.Refoam woofers
2.Find those diaphragms for the tweet and horn. (I will use the black ones but would prefer originals
3. If anyone can PLEASE HELP ME answer the questions in POST #63 of this thread, I can get on with the crossover repair.
