Why did you go to the stretched wire, then? Wasn't the welding rod easier to use?
The only advantage to using welding rods is that you don’t have to build a stretching jig, as they are perfectly straight right out of the box.
And now the downside:
If using use light diffuser grids to support the rods (as I did), it’s a pain to run a glue line across every rung of the grid and the glue line tends to stand a proud of the rods’ surface rather than laying perfectly flush, as desired. Also, welding rods are only 36” in long so if you want panels taller than 36” you would either have to butt/solder them (very difficult) or butt but not solder them, in which case you would then have to connect power leads at both ends. And you would have to over-coat them too if you want an extra measure of arc resistance.
I opted for wire/oak lattice stators because I wanted my panels to look as good as they sound and also match the nice oak woofer box & frame assembly. The wire panels are also more finely segmented to give even smoother dispersion (beats any curved panel, hands down). The biggest headache with wire panels is designing a proper stetching jig—and mine works perfectly. After agonizing for a considerable time over the jig design, building it was fairly easy.
The interlocking oak stator lattices were a bit time consuming but not all that hard to build—I just cut and profiled some boards on the table saw and router table and then sliced out the individual pieces (from the profiled boards) on the table saw. Some woodworking experience is required but you don't need to be an expert (I’m not).
I would be happy to provide dimensioned CAD drawings for my stretching jig and stator lattices to anyone who wants them.
I can tell you that I would not build welding rod / light diffuser stators again. In fact I still have the ones shown on my website which I would sell for less than it cost me to build them -- but then the buyer would lose out on the biggest reward of all, which is the DIY experience.
