It's been a few years  since I posted on my horn build.  Here's a picture showing the system's progression. Some notes: I ...

The horns are finished.  Check out the website if you haven't already. All of the content from the blog is organized here, plus some: ...

The blog format made it tough to organize content, so I archived all of my builds on the DIY Firefly  website .

From this perspective, this horn looks huge ( it's not really that big ).  I made some more progress on the horn and devised a nice way...

After researching mid/upper bass horns for several months, I used Hornresp to model a 100 Hz conical horn for a pair of EV-15Ls I had lying ...

After building the Buschhorns, I'm back to my front-loaded horn project.  While I decide what to build for mid/upper bass horns, I figur...

So, I took break with my front-loaded horn system because the weather is getting too damn nice to not have some sound in my new sunroom....

TWINS!  I completed the matching horn exactly one month after I finished the first.  Two kids, a full-time job and commute only left me wit...

I originally planned to finish the horns with shelac--my finish of choice for just about any wood project.  I tested shelac, and I just did...

I used a spongy sanding pad and stepped through grits from 60 to 320.  The horn shined up even without a finish.  I read of someone using a...

I just glued the top three layers to the rest of the stack (no screws) because, being thinner, I didn't want to risk punching through a...

Knowing nothing about using a lathe before starting this project, I asked a veteran wood turner who I saw at the Marin County farmer's m...

There are several ways to glue a stack of disks.  Erik (from volvotreter ) used a 2" rod to center the stack.  I didn't have a 2...

  Cutting out the centers saves a lot of time at the lathe. I used a 2" fornster bit and used the screw hole from the circle jig as a ...

Except for the wider base necessary to mount the driver, I aimed for 2" walls with a width of 1" at the mouth.  I used the printed...

I determined the width of the horn near the throat by measuring the driver mounting and approximating how wide the base of the horn should b...

Most endeavors start with a plan (some of the best started with a mistake, which is content for a different blog).  In this case, I started ...

Erik (from volvotreter fame) built his lathe (see picture) from salvaged parts in scrapyards in his area. Wow. I wouldn't even kno...

I've wanted to build a front-loaded horn speakers for a while now, but the low (maybe even negative) WAF factor put the big ixnay on my...

Welcome to DIY Firefly. This blog focuses on hi-fi audio components that I make from wood in an average basement shop in the Chicago burbs....
