Early model Six

[wilson]

Hi folks, I picked up a pair of Model Six's this afternoon at a thrift store. After doing a bit of research I've come to the conclusion that I probably got a pair of the early epoxy versions. I was very happy with my find until I realized that they probably don't come apart. Walnut veneer with nice original grill cloth (the boucle type). Serial # 070102 and 068844. Both tweeters measure open circuit from the back posts.

From my reading I've gathered that it is possible to get into the crossover from the back? The rectangle aluminum back plate is held on with 8 pins - do the posts and toggle switch stay with the crossover or can they be left attached to the plate? Can I actually get at anything from under these plates or am I just going to find a block of epoxy?

Thanks for any help - I'd hate to give up on these without at least checking the crossover.

If you do a search both here and over at audiokarma.org/speakers you should get some hits on threads that detail ways folks have figured out how to get inside these beasts.

Good luck.

Hi there

You will not get a reading with your VOM with the tweeters.

The capacitor blocks the battery juice.

You should be using no larger than 1 1/2 volt battery, not larger.

It you touch the + and - battery terminals to the speaker contacts you should hear and see the woofer respond slightly back and forth.

Perhaps another member knows the serial number breakdown or just use a flashlight through the grille cloth in the dark.

Well, It looks like these do have screw in tweeters so I guess that sacrificing the grill cloth is not that big a deal. It will also give me the opportunity to permatex the woofer surrounds.

Is any of that nubby boucle fabric available - or do I need to move to AR style irish linen?

Thanks.

Hi there

If the grille cloth is acceptable in appearance, there is no advantage to replacing it.

In fact, using the wrong cloth material can be detrimental to the mid/upper frequencies.

The grill cloth is great and I would love to not replace it ... but it seems to be the only way into these early 6's other than cutting out the backs.
