Evan:

Just made an interesting discovery, although I shouldn't be hugely suprised considering my above data, the speakers overall impedance is vastly different.

Factory Spec:   8 ohm
Good Speaker: 3.7-3.8 ohm
Bad Speaker:   7.8 ohm

Anyone want to start a brainstorm?

Are you sure both drivers are equal ??, seams like a 4 ohm and a 8 ohm.

You should have +- 8 ohms on both, so something is wrong on the one called the "good" driver. measure again (directly on the terminals both should be the same +-) and while playing check with a finger on each cone if the vibration is the same, sound set to mono, or put in a 4 +- ohm resistor on in line to the "good" driver and listen again.

No the drivers are not equal.

The measurements you quoted there are not just the mid-woofers, but the entire speaker! I measured many times to verify and my numbers are accurate. Have a look at the table a few posts further up.

I've been thinking of adding in a resistor..

How could it change so much? What could have changed in the woofer(s)?

I think I'm going to have to sleep on it! Plus its late!!

Hey Ev Buddy,

No need to respond just wanted to say I've been reading w/great interest the latest post

 between you and Soren on the divergence in opinion on yours and his readings.

this is so educational and I can't wait till tomorrow. of course thanks too you Soren for your contribution.

Todd

I need all the learning curve I can get!

If in doubt, try swapping drivers between the good and the bad speaker.
One at a time and see when things change.

Hello Martin,

That sounds plausible but as you know Evan's the expierienced one here; I'm trying too learn so I will point your suggestion out to him if he hasn't already checked for the latest post this morning.

Thanks,

Todd

Fixed that for ya.

I was hoping no one would say that! These woofers (like every other RL), are cemented in place!!

Good Morning All,

We are about to open up shop and all comments and suggestions are welcomed. Yes if you want to be so brave as to edit my post as Rich on Martins behalf! Jump In the water is a little choppy but warm  So Rich I yield to your edit but Evan, well thats another issue between Techies that I will have fun watching. So come and lets make it another fun and productive day. Alright Lets Roll!

Here is Todd taking off the bezel that keeps the fabric from coming loose.

No, just sitting a little hard with a rubber gasket, pry it out slowly and carefully, prying all around the driver basket, with a wide bladed screwdriver. Reinstalling take care not to pull the screws to hard, and all screws with the same force.

Thanks Soren. Yes, I know they aren't actually cemented in place. I feel like if I tried this I would end up damaging Todd's beautiful speakers. If it comes down to it, we may have to swap them but for now, he has decided not to.

Alright Leslie! Here is the part you were waiting for!!

Here are the RLs, freshly skinned.

Todd, are you holding yours upside down?!

Ok, for now that is all I have time to post. We did make a good deal of progress, but you all will just have to wait and see.

Todd and I both have to head out for work. I will post the rest tonight!

Uncool leaving us hanging. 

Get an 8 to 5 job!  (And a turntable while you're at it.)

What can be more important than a BEO speaker repair, OK boys will wait, but I dont like it

You are fantastic, brotherhood first class! Wish I could stand between you guys. It's great to see members live on pictures. Maybe tomorrow I will show you a picture of me working on my Beocord. It will be a fantastic day tomorrow with lots of sunshine.

Somewhere on one of my hard drives I will have to dig up the photos I took of the process i used to recloth my Red Lines a few years back. 57 days and counting - up,

Agree Leslie, these young people give us an example to follow.

Good to see you again, we missed you, and congrats to 57, keep it up, as long as your bike keeps up I dont see a problem.

Now I (55) feel old Søren but you're right. Beautifull people to look at and with lots of skills....

And..... Eugene is back 

If Evan is stupid enough to bring him around me -  Todd's Beotoast. One listen to my rebuilt 4000 on a set of S75's or a look at me rebuilt 2000 or me rebuilt 5000 or my 2400 or my BS3000, CDX, BC 7700... oh nevermind..... !

Congratulations.  My oldest daughter is now 4 years, 9 months, and 20-odd days, which means it's been 4 years, 9 months, and 20-odd days for me.  Good luck.  I wish I could tell you that it gets easier over time, but it really doesn't.  The psychological and social triggers just never go away.

He'll have to look at my fixed BG4002 later tonight...

Did you just coin a new term?

I work 9-5 tomorrow, any better? As for the turntable - you must be patient! Haha
