    Default LSi15 crossover schematic

    Hey everyone.

    I'm looking for an LSi15 crossover schematic. Searches turn up nothing but dead links. Does anyone have a PDF that they can send me? Thanks.

    Maybe I didn't do the PM correctly. But I never got a schematic...

    I put on my thinking cap and figured out my problem alone without the schematic. But I'd still like a copy if anyone out there has a copy. Anyone?

    When I was at Polk (last month) I spoke with Stu Lumsden (VP of Engineering) and he informed me they were removed because all of the more recent speaker designs were posted as well (unintentionally). So they decided to remove them all. He didn't tell me of a plan to repost at least the more vintage ones. I hope they do at some point. Hope this helps. Cheers.

    I was at Polk yesterday for a conference call and wanted to address this with Stu but he was not in. I guess he was out in Vegas at CES and possibly taking some comp days. I will address this issue with him and let y'all know. Cheers.
