richieb Posted March 15, 2004 Share Posted March 15, 2004 So I do not continue to bother eveyone with questions, is there a site on this forum where serial numbers can be matched to manufacturing dates? If so, does this also tell what drivers and horns were used in that series. On this same topic, LaScala with serial numbers LSBR- 31Y745/759. Is there something wrong if the numbers are not in sequence. Each cabinet was also tested by a differant individual. Does this indicate they are not a matched pair and if so, is this a bad thing. Are the above numbers a good year with the birch cabinets and alnico drivers. Help is always appreciated. Rich Quote Link to comment Share on other sites More sharing options...

Tom Mobley Posted March 16, 2004 Share Posted March 16, 2004 richie, those speakers, while not having consecutive serial numbers, were probably made on the same day. they're only 14 apart. And sure, they probably had more than one inspector working. All that deal really means is that they were probably shipped in a large lot. Nobody much cared about consecutive serial numbers then, the speakers were built to a quality control standard. Any two off the line are a matched set, unless there were driver changes or something. Trey or somebody from Klipsch discussed this awhile back. My own Heresy's I bought new in 78 are not consecutive. When I bought them we just went into the back of the store where there were about a dozen or so stacked up, we just pulled the first two and loaded them into my truck.
