    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...

    Yeah, yeah... I was admiring the clamps! I have piles of "Pony" clamps and Jorgensen pipe clamps, but those Cabinet Masters look awesome!

    Great work, keep this pics coming!

    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:

    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.

    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.
