    Re: Identifying original 515B cone

    The horn is markus klug's wooden 1505.

    This will be a long term project. Once the 817 is done I will play with the 288 swapping it out with TAD 2001 or adding a TAD tweeter, to check if it works. I am buying the Altec drivers now because they go up in price. The speaker gets built after I move from my current place to a new one which is a while away.

    Ignore the 6, that was a typo. I was about to say the serial numbers are separated by 116 when my mobile when I must have typed in something wrong. Anyway based on what you said the serial number could be done over a period of time. The cones do have 21184-3 however

    What's the best way to store. If each driver is kept in an individual box, or together, does the magnet affect anything? Also, can stuff around the box affect the magnet?

    Guess it depends; I stored a pair of NOS 421-8H for years facing down in their boxes, but Ga. heat caused them to eventually sag completely out of the gap, so placed them face up and many years later they were bottomed out, so placed them out in the Summer sun till they slid back in and been storing them vertically in the Winter and regularly rotating them in Summer heat ever since to keep the surround goo from messing up the gaskets.

    Interesting. So vertically over winter is the answer
