Default Dimension 8 tweeter replacement

Hi, all.
Pair of Goodmans Dimension 8 speakers for overhaul.
Two of the 4 tweeters are dead but still sounding pretty cool !!
1" soft dome in a kind shallow horn loading faceplate.

Units are Goodmans made, marked DT3.

They are crossed over at 4kHz.
Efficiency: dunno.

Looking for advice on a modern sensibly priced equivalent (i'll want to do all 4).
Or any info that might help narrow down the field greatly received.

Thanks in advance.

I'm finding a little info on the net regarding these Dimension 8's but still a bit stuck with what to replace the DT3 tweeters with (particularly since I'm not sure what the target sensitivity is).

However, I have found a website with what looks like a scan of an original brochure.

The specification quotes:

"Sensitivity (DIN) 4.4 Watts"

I've not seen this method of characterising sensitivity before - anyone have any idea howto convert this to the more "useful" dB/W/m.

Any help gratefully received.
