Relative merits of this vintage tweeter?

[Brisso57]

Panasonic (National) EAS-5PH18S
6 ohm
2" paper cone
"Japan 713(c)"

Can anyone share an opinion on the quality of these tweeters? I have two that came to me as 2-ways, crossed with an 8" WR, using a 2.2uF series cap.

(Looking for a helper tweeter for a Sanyo "103" clone.)

Thanks

PS It'd also be helpful if someone knows their sensitivity.

Brisso, FWIW I've found that most Matushita (now Panasonic) drivers (they all seem to start with 'EAS") are a cut above most roadkill drivers I've collected...
I measured a panasonic tweeter recently and it had a flat response from 4Khz up, sorry, it's back in the box now so can't tell you the model no.

Hi Pete,

Here's a pic of the Panasonic tweeters. Recognise them?

Doug, sorry, mine don't have the big flange at the edge (I think mine are relatively recent & a tad smaller)
