Rogers LS4a Tweeter Replacement

Hi all -

I have a pair of Rogers LS4a's that I dug out of storage and have finally decided to resurrect. One tweeter is blown.

The original tweeter is a 19 mm aluminum type manufactured by Seas - Model H414 TAF/G. They are no longer available. In my research, about a decade ago, it seems like the accurate replacement became the Model H0532.

However, now it seems that this model is no longer readily available.

Before I reach out to Seas directly, I figured thatI would post on the forum to see if anyone knows of an alternative tweeter that would work well or a source for either of the Seas recommended ones.

Thanks!

Jon
