Heresy II serial #s/dates


Islander

Recommended Posts

As I've mentioned in other threads, last week I became the happy owner of a pair of Heresy IIs. Naturally, I wondered what age they are, but when I checked the part/serial numbers, they didn't seem to match any of the lists I've seen, having more digits, for one thing. I searched through all the related discussions (just so you know I did some homework before asking this question) and I think they may be 1990 models, but that's sort of a guess. I haven't taken out the drivers to see what's marked on them.

Here's the relevant info: They're marked H II Fin. Blk Part # 09000351210 Serial #s 37804 and 37805 w/o 6943

All that is on a paper label.

The binding post plate is square and has Heresy II molded into it in raised letters.

Do these numbers make sense to anyone? Thanks.

Islander,

Earlier on today I was looking at the key sheet that has now been posted above and can't make sense of the serial numbers. They seem to be too few.. One thing i'm not clear about is "w/o 6943" Is that part of the serial number? Does it appear on both speakers. That looks like it could be indicating a year of manufacture of 1996.

DD, you see how the numbers don't conform to the typical arrangement. I'm guessing that w/o refers to a work order or production run. That number does appear on both speakers. They both have that same 11-digit part number and the 5-digit serial numbers are on a separate line, with the w/o number on a line below them.

If they turn out to be 1996 models, it would be cool to have some relatively young speakers like that.

I spoke with Steve Phillips (thanks, Steve!) and he was able to narrow them down to 1990 to 1992. I'll have to pull out the woofers and check their numbers to get more specific dates, but that's close enough for now.

Apparently not. Steve said that in the 1990-92 period the serial numbers weren't consistent with the usual patterns and that the part number indicated black-finished Heresy IIs and not much more. He wasn't sure about the w/o 6943 either.

Islander,

Thanks for the interesting thread. I've never tried to ID any Heritage speakers (by serial number) of this particular vintage. That's good to know that there are some exceptions to the usually posted scheme. Otherwise, I'd just be wondering when the heck were those built.
