    Anybody know how to contact the OG?
    I've acquired all components but can't find the actual plans. After completion (and presumable awe) I'd like to drop some love on the original designer, but the "Greenboy" website-links all seem dead.

    Also, "Speaker Hardware", the suggested and endorsed crossover-builder, has contact links that always spit-back as "undeliverable". Fn annoying because after purchasing their full complement of xovers for a pair of 15/6/1's & Sub 15 (=$$$) they won't answer a few basic questions.
    1. - Why aren't the two tweeter xovers (for the 15/6/1's) built with identical components, and could that be a liability for matched L/R cabinet sonics?
    2. - In Sub15, is there a problem inserting a simple "Sub/Direct" bipole switch after the jack, "Y" ing to crossover & direct to speaker?]

    Any leads greatly appreciated.
  2. I know Greeny. He’s off the grid. A mutual acquaintance got a call from him a few months ago, otherwise he’s been radio silent for over a year.

    Anybody know why [it seems] G-boy advises against using screws for additional strength/rigidity in addition to the PL Premium during cab assembly?
    Purely aesthetics, or sonic considerations?

    Okay, KUNGfu; thx for info.
    So... if somebody wanted to paypal him props for his generosity with his research/design knowledge, do you know if that's doable? I'm not talking a million bux here, more like a case of beer, but it'd be nice to be able to extend "Thanks!"

    Re my design questions, without the "Official" plans I'm going to combine the bits that I was able to cull online with my gut instincts. Hopefully, they'll still hit the notes when singin'.

  6. Not a clue, but I can put it on the grapevine if you’re serious.

    He’d probably appreciate dirt bike tires more than beer.

    Went to the site: cannot find the "register" tab. "Login", plenty, but I'd kinda' like to be registered on the forum if I'm going to make a donation. What, if you donate THEN a tab magically appears to join the forum?

    I'll gladly throw 'em some bones anyway, but registering on a forum isn't typically this covert.

    Could well be me. I'm getting dumber with age.

    I don't think that anyone is moderating the forum anymore, think it'll be a while before anyone sees your request.

    Okay. Thanks. I'll drop some props anyway @ [screaming] paypal link. Cheers

    I don’t think you have to pay to register. It looks like there is no way to do it except asking in the welcome forum.

    There are a lot of detailed build threads here on TB. You might try asking your questions here:

    I don’t think they’re accepting new registrations. There was a thing about that I saw somewhere where they said their ongoing requests for at least some support donations for the forum went almost completely ignored so they finally decided to stop moderating the board and just leave it as it was. Which means if you are already registered you don’t need to worry too much about spammers. But if you’re not you’re S.O.L. and stuck in read-only limbo since only a nonexistent mod can activate an account.

    I’ve built several of his and BFMs cabs. No screws or nails needed. With 1/2” plywood, you are more at risk of splitting the wood from screws, even predrilled. You can however, use small brads during a dry fit for registration as PL Premuim is slippery stuff.

    Thanks, folks.
    I received responses from the "Authorized Builders" which answered my central concerns. Ready to assemble!

    A few notes:
    - I'm using 3/4" Birch ply [=11/16"], so I'm going to add 2" HQ coated deck-screws every 8"ish for added strength & rigidity.
    - Re the non-matching capacitor, presumably the substitution of 2 on one board match the rating of the single on the other and shouldn't create a sonic hazard.

    I'll move future posts over to "amps & cabs". Cheers

    Probably because they aren't needed. PL Premium is amazing. I've had a 12/6 for almost a decade that has no screws. I actually built it before I had proper clamps, so I used screws to hold it together while the glue dried, then removed.

    If you wish to join the GB forum you need only ask politely and the non-extant moderator will listen.

    With 3/4" stock, I certainly wouldn't use 2" screws, plenty of opportunity to skew and pop the laminations. 1-5/8" is plenty long, even 1-1/2" is plenty long. The strength comes from the glue not the screws (which just hold things in place while the glue cures).

    Message received and noted, thanks. I intend to accurately pilot the holes, and not so many at that.

    Where do folks typically mount the crossovers inside the cab? I'm building "True" 3-ways, so the three boards per-cab def take-up some square-area real estate. I was thinking about mounting a ply "spine" splitting the middle of the top & mounting the boards to it. It seems kinda' counterintuitive to simply mount them all on the back near the jack-plate thereby forfeiting a bunch of otherwise foam-mutable surface area. I'm wondering how much Studio design-rules apply within these cabs: be very careful with un-treated parallel surfaces.

    Then again, I'm just following orders here. My experience designing and building booths n rooms probably means squat to speaker design. Onward.

    with a bit of planning the 3-way xover can be built on thin scrap ply and mounted on top of the port shelf
