Have any of you noticed a difference on new vs older 7" HDS exclusives?
The older datasheets do not show a dip above 1KHz whereas the new datasheets do. Zaph's test seems to confirm the new datasheets FR.
The datasheets have different VAS leading me to believe that they changed the spider/surround without giving it a new part number. I also think the changes are more significant than just break in. The change happened around the same time peerless introduced the 831882
I bought and tested an 883 a while back, and don't remember that dip. Of course, I did not save the data and don't have the drivers.
Do any of you have older HDS exclusives that you can compare to new production, and show differences, either cosmetic or measurement based?
FYI, the madisound datasheet is the old one, Tymphany is the new datasheet.
