    Some photos of my 4345 clones

    Yesterday a photography enthusiast friend of mine came over to take some pictures of my 4345 project. He thought the woodworking would make an interesting lighting project. The pictures came out great, and I'm thrilled with the progress on the cabinets! This is the first time they've been even partially assembled.

    I have dozens of things to say about the project, but I'll let the pictures do most of the talking. Here are some answers to the inevitable questions:
    - All panels are 1" B/BB Baltic Birch including the baffle.
    - I cut the locking miter joint completely on the table saw. It was time consuming but I'm happy with how it turned out. That said I'll probably just use the router bit next time.
    - The mid-bass box is sloped downwards slightly on the top to fit a larger compression driver.

    I will upload some more pics of the construction later.

    Holy Batman. That's very impressive craftmanship here.

    Please explain how you do the joints...

    It's all because of the photography! I told my friend he should sell those photos to Jorgensen.

    7 cuts on the table saw. 3 dadoes, 2 bevels, 2 straight cuts. The error compounds so extreme accuracy is required. Slight bowing of the panel or variation in the pressure holding the panel against the table or fence will ruin the joint. Like I said, I think I'll use the lock-miter router bit next time!

    The hardest cut is the first one because you need to make a jig to hold the panel vertically:


    Here are a couple other pics, showing the jointing of the midbass box:


    I wanted to beef up the bracing over the stock design, but it was a tight fit! I was planning on more cross bracing and a sideways piece across the top, but there is just not enough room.

    Thanks everyone.

    And 4313b, I owe you a debt of gratitude for all of your engineering that is behind these:



    Also thanks to JohnW who modified the l-pads and added the zobel. This is the circuit I used, with a few tweaks of my own:

    Wow. The woodwork looks simply amazing! I haven't seen pics of a project here with neater cabinets at the stage yours are. The crossovers - man what gems. They look like '80's Japanese optics quality.

    I must ask - may you post a picture of your drivers? Even ones shot with a towel will do. Also - are you a carpenter? Where did you get those skills? This thread made my day.

    Thanks for the kind words, everyone. It means a lot coming from you guys. But really these are small accomplishments compared to some of the amazing creations I have seen from other forum members!

    I will post a pic when I have them, currently they are being reconed by the one and only Edgewound. I will be using 2245h + 2122h + 2425j (for now) + 077.

    And I'm no carpenter, just an enthusiast for all kinds of DIY. Anybody could do the same with enough patience and good tools.

    Please don't remind me! This project has been expensive at every turn.

    Good eyes, I'm surprised you spotted it! Unfortunately it's just a MIG, I'd love to learn TIG but that's a project in itself.

    Yes, following 4313b's design and the schematic in the link. There is still a lot of work to be done, hopefully I will have more pics posted within the next couple weeks.

    Judging by the personal skill you have displayed I doubt you will find it difficult, I personally don't find it any more demanding than any of the other common welding processes.

    I however will be staring at my table saw this weekend wondering how to duplicate your precision joinery.
    If we knew what the hell we were doing, we wouldn't call it research would we.

    The whole world is a Mecchano set , but it looks like you have made huge strides with the toughest one
    ' WOOD '

    You will enjoy that speaker . There is nothing better than hearing a speaker you've made .

    This is the best DIY speaker forum in the world !

    BTW ,when you can TIG aluminium over head ,you can weld . TIG welding stainless is easy by comparison ,but finishing it is a another ball game ... If you can gas weld ,you can Tig ... Practice
