    Wow, didnt think the 808-8As can go that low.... so basically a first order on the tweeter and you run the midrange without a high pass filter....

    You're welcome! Jeff's been very helpful to the Altec community. He was the first to respond to a query when I got online and the late Bill Eckle second.

    Yeah, me too. Dr. Geddes drives DIYers and boutique vendors 'up the wall' when he states that even cheap HT amps are so good/clean, etc., that they're a non entity in today's high SQ, etc., world, just a commodity like toilet paper, so no need to pay for more specs than needed for the app.

    802, 808 are rated for 500 Hz/30 W and personally have used them at 300 Hz/7.5 W.

    For sure...
    Does @bfish still haunt up this place?
    I remember he supplied a very useful link for co-axial design.
    Further down the article is discussed ?shading? and the potential destructive interference based on the size of the inset horn. Interesting!

    Sadly, no; he drifted away not long? after your build and we kept in touch for some years, then nothing I can remember beyond a PM in 2010 when he sent me this even though periodically try to find him: raw?appidYMailNorrin&ampymreqid8d3d3bac ea28 1ec3 1c77 700007011100&amptokenzitEzqOML3j84e6ealFTT5U7 km5qEQF52lp7AcCuBZvePl0PHX2dwhQvRcMSC0J7BsOlHuxewd2ykFZ75Odhjdh4ZZgAEDb2PY11HAhICkaXYsR4RvwvgV3QYEmzl84

    Bummer! I see it fine in both my post and yours, so don't know how to correct it. Anyway, it's him holding a big fish he'd just caught.

    That said, beginning the other night I quit getting updates, only to find them in the SPAM folder as it's now coming from a different a different source that Google doesn't recognize, so wondering if I'm FUBAR'd somehow and Avast Antivirus didn't catch it. I posted on the HELP DESK, but no response yet: HostBoard<[email protected]>

    I kept in touch with him via email for some time after he left the forum and then one day responses stopped. One helluva nice guy. The 416-8Bs he sold me are in regular use.
    Opinion is only as valid as its verifiable supporting evidence.
