Yes, the Seas tweeter is one of only two or three tweeters made (last recollection????) that is even capable of going down to 1500khz. And actually make music doing it!Some claim to go that low but it's basically bull. The 27TDFC is a very robust tweeter particularly in that low end. If you ignore the cost (the corner stone of audio sales) the Seas tweeter IS one of the best made today.
BTW - this is going to be the next Seas classic speaker.

Hi MP3, Airtime and Krank were both right.
Dynaco answered your question around 1973 or 1974 when they came out with the A-25XL. They knew the A-25's tweeter dropped off before the range of human hearing so they came out with the A-25XL. The XL used the Seas H-86 tweeter instead of the H-87 that was used in the A-25. The XL was more efficant and had a slightly different grill that used Velcro so that you could take it off easier, and the grill was slightly bigger, you could see less of the wood veneer on the front of the speakers edge with the XL.
I had a question about taking the screens off the tweeters concerned about diffraction occuring but someone told me to leave them on for another reason beside rowdy pets or people of which I can't remember why...Mark Korda
Thanks Mark, Charles and Krank too.
I owned another pair of A-25s maybe 30 years ago. With those I added wood bracing inside the sidewalls, just above the woofer, then replaced ALL the stuffing. I also installed a new crossover cap and removed the mesh screens from the tweeters. At that time I could hear improved detail and extension in the stock tweeter without the screens.
Now in my elder years my hearing is lost above 8K. So I removed the mesh from the tweeters in my current pair based on past experience. Possibly I should have tested myself to see if I could still hear the difference but I didn't do a before and after comparison. Anyway, that is why I was asking about affects of a tweeter upgrade more for midrange performance. So hopefully the new Seas model will be positive in that respect.
