My TABAQ Build Thread

[Consul]

Okay, I thought I'd start up a thread documenting my TABAQ build using the W3-593S drivers, which I bought on sale from Parts Express. I still have yet to do any real work, but I'm hoping to get the entire thing knocked out from here through the weekend. I've attached my first photo, which shows some of the parts.

This is my first loudspeaker DIY, and I'm quite thrilled. Thank you all for helping to make this possible.

You're a lucky guy I keep dreaming of doing what you do, but i'm not really a wood-working man.
I will follow this thread to see how you're doing.
Maybe you can inspire me to finally get going
Have a nice week-end

One of the reasons I picked this project is because I'd like to hear what a transmission line speaker sounds like. It was just luck that an appropriate driver came up for sale right when I decided to take the plunge.

Here's a pic of the first MDF board marked up. I bought 1/2" MDF in 2x4' sheets, one per side. I'll have plenty left over for something else. 1/2" is just a hair thicker than the 12mm called for in the plans, so I cut the top and bottom pieces just a little wide to compensate. I'll probably have to shave them down a bit to make them flush, but that's no big deal.

Blargh! Wouldn't you know it! We have rain in the forecast for the entire weekend. Unfortunately, outside is the only place I have room to work, and cutting MDF in the rain seems like a bad idea. Hopefully, there'll be enough clear moments that I can get some of it done.

I'm just using Bjohannesen's stock TABAQ design:

It's a simple and straightforward build, designed for the 3" TB full-rangers, so I think it'll suit a first-time speaker builder just fine.

Good luck with your speakers! Having just completed a speaker project with MDF, I would wear a respirator when working with it. It is nasty to work with and contains around 9% formaldehyde glue(unless something has changed that I don't know about). Peace. Robert

Of special interst to me is how you do up the crossover. Pics of that and the layout will be much appreciated if this is going to be a real detailed thread.

I have a TABAQ for WS 871s made but am real shy of doing XO work. Have been for years.

It's not a crossover, but rather, a baffle-step compensation circuit. All it is is a coil and a resistor run in parallel, along the + connection to the speaker. I'll be sure to post some good pictures of how I solved the wiring and mounting problems.

I should get out my Speakerbuilding 201 book and refresh myself
on the difference.

Without electronic background but coming here to read about building, I get lost in the finer aspects of the hobby. It's been explained to me that connections in parallel are the component end wires twisted (or soldered) together on the plus line of the speaker.

Your tutorial will most helpful with the visual clues to construction.

After seeing many years of Speakerbuilder magazine, I've always
thought that construction articles should have three parts: picture, diagram and schematic to show those relationships.
