Cone sag

[jim henderson]

I just bought a 2226 off of eBay and noticed that the cone/spider has sagged as if the driver has been stored face up for a long time. The offset looks like quite a bit but measures only 0.170”. Is this going to be a problem? If I mounted the driver facing down would it eventually correct itself?

Can you post pics that show what you see?

Any evidence of these having been previously worked on?

I don't believe you can "restore" a sagged spider. Recone...

I've seen this before and often wondered about it. Doesn't this have to come from the suspension shrinking up or a long time DC bias which I'm inclined to think would probably fry the coil. This was intended more as a question than the answer.

Well the 2226 has a pleated surround and is "relatively" new - that's why I was hoping for some pics.

I don't own any, but the 2226H have a natural position where the surround descends slightly from the basket edge. I don't know if the spider is "flat" in rest position...

This recent eBay is clearly a recone with non-OEM kit - note the:
- oversized dust cover
- four instead of three pleats
- lack of exposed leads (TOP pic)

... all as compared to the stock design (BOTTOM pic)...

Hi,

is this something to be concered about with the Model 19 speakers?

How would i know if the cones are sagging? I think these might have been sitting for a long time.

thanks
