i used 1/2 plywood. it was actually sandeply. if you can get a hold of birch that would be even better. the sandeply tends to splinter a bit, so it needs to be sanded on the edges really well.

Hi Craig, enjoyed looking at your build. I am going to build a pair soon. Did you use 3/4 ply or 1/2. Hard to tell from pics. I know the plans call for 1/2. Just curious

I am hoping to build a pair of these soon but can’t find the pictures you refer to. Is there a link I’m missing? Thanks.

Basically (and you can sort of see it if you review the pics) I changed the back a bit from the original design, and added a rabbet on each side of the back so it fits snugly in the enclosure. Then I just screwed the back down. Before completely sealing it with caulk and wood putty, you can experiment with different damping materials and amounts. You do get some air leakage doing this, but it gives you a good idea of how much and what to use before completely sealing it. I didn’t glue the back on so worst case you can always unscrew and remove the cover even with the caulk and wood putty seals. I’m sure one could experiment with rubber seals as well, but that would increase cost and build time.

You mention experimenting with the damping materials but how are you able to continue to open and close the speaker enclosure? Thanks.

OK. I’ll play them for a while. I mounted the backplate with screws only to be able to experiment with different damping.

When I built my two pair, I gave one pair to a friend of mine who happens to be very good with speakers. He gave me some damping materials, and we experimented. Basically, we used some light filling throughout, and a little at the interior opening of the port at the bottom. With new drivers, they need some time to break in, so I would run a source through them for about a week straight to break them in. Music at a low volume will suffice.

We also put some rubber diffusion matting right behind the driver (epoxied the matt in place.)

You just have to experiment to get them the way you like them.

Hi- I just buil my Zigmas. I found no indications of how much, if any, damping is needed. So far they sound very edgy, but the drivers are new.

Thanks Jeff. I’ve been pleased with the performance of the Zigmahornets so far. They sound great, especially with good quality recordings, jazz, vocals, and classical music.
