Hi,
I have a older set of Heresys that I I purchased used back around 1977, they came unfinished w/o grills but do have the gold Klipsch logos on the front of the cabinets above the tweeter.
The serial numbers are:
47R039
47R040
On the label from what I can make out it says HL BR
(sorry ran out of room for the other speakers SN)
They are both still working but one of them when I purchased did have a hole in the woofers dust cover, it never affected the sound and I have been getting around to replace that ( yeah since the late 70s 😉
Would the dust cover be available from Klipsch?
Back to the sound they still sound ok but I was wondering if it would be a good idea to re-cap the crossovers and if so would the parts be available from Klipsch?
