They look really good, Doug. Horns always look pretty cool when they're assembled down to the last panel so you can see the guts. It always gets me wondering how the compression (or whatever magic they use) happens.

Re: Doug's dual GJALLARHORN build

Horns provide better coupling of the driver to the air by converting high pressure variations with small displacement in the throat into a low pressure variation with a large displacement at the exit.

(answer provided with a little help from wiki )

Silence is golden but duct tape is silver.

I hate to cover up all that work never be seen again to end up with an ugly box. I have lots of photos I can refer to in this build log if I ever need a trip down memory lane.

Re: Doug's dual GJALLARHORN build

I measured all of the holes for the bolts and prepped the areas for the t-nuts just like I did for the baffle - but not as deep since there is only 3/8" to work with. I like to marry the bolt and t-nut just to make sure there is a match





The bolt in the t-nut makes a nice way to hold it for applying the glue - Gorrilla glue or epoxy, whatever





I hammer the t-nut in from the head of the bolt so that it sits flat with the baffle right after I apply the glue so that the glue doesn't drip though the pilot hole. I flip it all over and use a washer and pull it together to get the t-nut to grip.

It's coming along nicely! Looks very good so far, I wish I had wood working skills like that. Lol, and it's awesome that your wife is participating. My wife wants nothing to do with my audio equipment.
