Linaeum Tweeter - Please Help
I got a pair of the ratshack linaeum tweeters cat. #40-1389 from e-bay. I plan to use them with my old KLH 6 speakers with a 2nd order high pass at 3 kHz.

I know that I need to bypass the capacitor in the linaeum, but haven't figured out how to get at it. If I go in through bottom, the plate with binding posts won't pull off. If I go in through top, I can see capacitor, but can't really get at it.

Can somebody who has used these tweeters tell me how you got at the capacitor?

Do you have a picture, I'm not familiar with that tweeter but I assume like some of the others there is a connector on the frame, a casing and the cap is inside the casing??
was this tweeter meant for top mounting on an existing box like the Fostex super-tweeter??

Hi, there is a manual but it does not help much, :)/sreten.

OK I have seen them.
Query, if they are designed as an add-on top mounted tweeter why are you not using them as designed?

I have a pair of the Rat Shack Linaeums that I pulled from defunct speakers. But they don't look like that.

Mine just pulled off the top of the speaker, no problem.

Sure hope you find someone who knows this stand alone model. Good luck!

Photos of Linaeum
I'm attaching photos of the tweeter. Hopefully they will be included when you look at this posting.

The reason for bypassing the capacitor in the tweeter is that I want to use the tweeter with a better crossover.

I suspect that the answer is to undo the two screw that hold the tweeter to the mounting plate.

Sorry Guys,

Here's some photos on ebay that show inside of tweeter.

Don't use preview when you post.

Yes, i'd pop those 2 screws... i have a pair of those somewhere... buried deep thou, haven't seen them in years.

After popping those 2 screws you may find a good cap, but probably not just a 2uf NP 45V.
I'd use them as they are and as they are intended to be used foe a while and play with them only if you need to, the sound/look like the thing I need for a new OB project for freinds, rather than using two tweeterd front and back

IIRC the elco cap is bigger than that, there may even be a choke (there is in the Foster pod tweeter).... they do desreve poly caps, i'd get in there and swap the cap out at least.
