    4345 Monitor Plans

    I wanted to post these earlier but they needed to be cleaned up and made a bit more presentable. All of the dimensions on the attached drawings were taken from actual cabinets. I would urge any interested 4345 owners to bounce the data off their actual cabinets.

    I have a few other detail drawings I will add later but the info here is sufficient for use should someone decide to start building.

    Note that I have labeled the port diameter as 4" I.D. The cabinets I took these numbers from were actually 4 1/8" I.D. Earlier in this thread Bo posted some pics with a tape measure layed across one of the ports. From that pic the diameter looks closer to 4 and definately not 4 1/8. I would hope there are both out there. Tubes with 4" I.D. are readily available. 4 1/8" will be hard to find.

    I thought this stuff would end up in the DIY category. I did a search to find the old thread and just added on. Moderators - please move it if you think it belongs there - maybe as a new thread - although all the info should stay together. Sorry!

    Thanks once again Rick.

    Plans put to use...

    I'm just finishing up my pair of 4345. Thanks for the excellent plans and the volumes of help from the forum for crossover and other design elements.

    Great work as always John. Nice shot of the budding Vanna Whites too. That really puts things into perspective.

    Thumbs up WOW

    OK, your's are better than mine! After carping as I have about members building 4345's, I shall carp no more. You and Ian have proved that building is well within the realm of possibility. The level of talent and comitment you have exhibited is beyond outstanding.

    I hope you don't mind becoming a source of advice for builders and owners, because I am starting things off with some questions of my own.

    I was going to upgrade the crossover components of my pair this winter, but your network is obviously a clean sheet. Is it from Giskard plans? Are the plans available on posts in the forums? I see it is charge coupled and involves only two L-pads (so I know you are bi-amping). Most of all, how does it sound? (I know you need some time to evaluate before attempting to answer.) What did they cost, how did you chose and where did you get the components?

    The pic of your girls is priceless!

    Congratulations, I hope you enjoy them as much as I do, Clark in Peoria

    Thanks.
    Very nice work on the recones of the 2122Hs SpeakerDave.

    I'll post the crossover schematic I'm using tomorrow. Yes, it is Giskards equivalent, but I left the lpad off the 2122h and modified a couple resistors on the 2405 and 2425 to maintain the impedence and reduce the padding a little. Sounds great to me, and measured quite flat on the RTA.
    I am still planning on building some grill covers.
    I made 4 or 5 attempts on some foilcals, but nothing looked acceptable. Komodo has offered to make some, but the minumum order would be 5. Let me know if you need a pair of emblems, and if there is enough interest I will order some up. Right now, I kind of like the JBL badges put on a dowel and stuck in the LPAD hole, since it isn't being used anyway.
