Klipsch Hersey Speaker I.D.

[timespy]

Hi folks, its been awile since ive posted on AK, but I am in need of your expertise. I recently came across what I believe to be a pretty good find up at my in-laws cabin. A pair of Klipsch Hersey Heritage series speakers. I have been trying to look up the date these were made, but the serial numbers arent making alot of sense. The numbers are 152y996, and 997. This tells me they are in series, but I cant seem to decipher the numbers from the I.D. charts I have been able to find. If anyone can I.D the dates on these, or steer me to a chart that can help, Id really appreciate it. The speakers sound amazing, and are in really decent shape. Im sure I didnt get a number mixed up with a letter because the paper tag is hand written, and very clear. I seem to be getting lost with the single y in the serial. I have also looked inside for any Pride tags, and there are none. No pencil written notes either, other than the mumber 32 on the side and bottom inside the cabinet.
