Not bad for a beginner. Seriously, well done and thanks for sharing.
Little confused about referring to the midbass as a "J Horn". .. which to me implies a horn in the shape of a "J". Or am I just not informed in the art of "horn speak"?
The model is called that, I don't really know why🙂
Very impressive DIY system, nothing like the sound of horns 🙂. Not having the means, I had to make my own horns out of scrap wood and paper...still weigting more than 1200 pounds totally 😀

Thank you! Horns are fun, no doubt!
Lego for big boys.
Completed set. Later had the nuts replaced with furniture caps for a smoother look.

Have you considered using dense birch plywood of the same thickness instead of Alu? I mean there is not that much stress on the structure and the $$ savings would be considerable. Plus the warmth of wood...
It would be more expensive to do them over in any material😉 seriously though, I did not pay much for the job and aluminum looks way better than plywood. I did not go for aluminum because of the strength, at least not for now. Should I go for a larger ALE driver the case might be different😉
About 2% of the project budget was spent on the stands for mid and tweeter. Not wasting money, IMO.
more please !
Please, if you could, take a picture from the listening chair and offer a complete description of the signal chain. This looks like superlative work ! 🙂

Patience, we'll get there soon enough!🙂
About the same time I got both First Watt F5s up and running. I got brackets for the transformers, PSU boards and chokes custom built. Dual mono CLC. Very happy with them.
Here are some details:

Back to the speakers, more details of the build.
Here's the threaded adapter I made for the ALE 4550 to fit the regular flange of the JLMC350. Stainless steel, of course.

At last, the 3-way satellite was up and running.
Here seen with the prototype en baffle bass units I initially had plans of finalizing to go with a 2-way horn sattelite. Since I later went ahead with the midbass horn, I saw the opportunity to build something quite different. I had earlier assisted in designing and building a huge SLOB with a friend and DIY mentor, and a plan started emerging.

I was at the moment playing with the stereo placed on the short wall of the room. Perfect for a bass solution with three 15" woofers per side. You can also see my working space where I designed the speakers, soldered the amps and programmed the dsp.

Can't quire figure out what's going on w your subs. I thought they were slobs or maybe I missed a post.
Any info on your choice of cones for the 515's? Curious minds want to know.

Seems like I have seen this gentleman's posts before, somewhere (?)
IMO patience is the key to letting this thread develop to it's full extent.
Great things could be coming our way. 🙂
