I have the modi 2 or 3 I can’t remember right now. I am using the USB cable with the camera adapter. Works perfectly with my iPhone XR and an old iPad. It is worth messing with.
edit: when I get home tonight I can post exactly which cable and adapter I am using. It works flawlessly.

Very cool. I will have to stop in the next time I am down there for work, or a softball tournament for one of my daughters.
I guess you are close enough that I could just make the trip. I would like to hear Jubes.

@Rudy81 I am taking the free moments I have to draw up some bases for the wings on plywood to get an idea of the size difference between the 7” and the 12” assemblies. My instinct tells me to build the 12” but they are significantly larger than the 7”. I think the 12” will match the bass bin better, but I really want to keep the heil as close to flush with the bass bin as possible. This will over hang quite a bit as seen in the pic. Some overhang is ok, but this may be a little much. My question for you is how big of difference did you hear having the heil set back as opposed to being flush or close to flush with edge of your bass bin?
I know I need to just try it myself, but I would like to get your input before I make some saw dust!

how does it sound like , any crossover needed , does it replace both the midrange and tweeter or are you adding the tweeter on top of the bow tie ,
Take a look at the thread linked above. All the information to implement this is located there.

I am going to experiment with the front wings overhanging the bass bin. My guess is the imaging will be a little better having the heil diaphragm flush with the front of the cab. We will see. The wings will hang out a little, but luckily my listening room is low traffic.

Looking really good!! I really like the way the 12” wings complement the La Scala bass bin.
-
When I first built my La Scala clones I had the K401 horns just set on top of the bass bin with no baffle. Without digging through threads I remember there being a distinct edginess to the sound that was not good. Multiple members recommended a baffle to mount the horn to. This worked well. YMMV.

Those look great!

My progress getting my stacked wing assemblies cut and put together has been slow due to a new puppy. However, I was able to get a die made this weekend to cut the bases of my assemblies with the router. I really want to try the AMTs right up at the front of the bass bins so I need to have the front of the base open. The wings will extend out in front of the bass bin pretty far, but I have some ideas to keep the cantilevered weight stable. I will try to get some bases cut for the 7” and 12” wings and place them on the LaScala bins to give everyone an idea of their relative sizes.

I am really not a fan of gorilla glue. I used it on a project that required a waterproof adhesive. It turned into a mess quick. Titebond makes excellent products. If you really need the bond to be strong and the surface is uneven I would recommend a polyurethane adhesive. I build my table tuba with it, much easier to work with.

I don’t know if it will make a difference. Can you trim a little off the ends that meet the top and bottom of the cab to achieve 33cm?

Roxul and ultra touch denim. Made a HUGE difference.

Can you post a pic of what area you are talking about?

She is 10 weeks. Ridiculously smart, unrepentantly cute.

I sure hope not! You're supposed to be my twin in this ESS experiment.
This project will be the exception. I really need to just sit down and hook everything up already. I do need to finish the base for the wings and AMTs however, the guard cat that inhabits my workshop is not very pleased about our new addition. Once we are back on speaking terms I will make some sawdust.

I think what is needed now is a test with wings extended to say 12" and then 18". That may really make a difference. I'll see what I can drum up in the next few days.
Very cool, great work @Rudy81 !!

Nice, I will also be using “La Scala” bass bins with the stacked heils.

MiniDSP arrived this weekend, but no progress made due to house painting.
just a little side note if anyone does not already know. According to the ESS website the purple wire is the positive connection, blue is negative.

@MicroMara your cables look very nice! Where do you source your expandable sleeving?

I had one more thing to try in my testing plan and that was to move the wings forward so that the AMT drivers would be flush with the front edge of the bass bin. This leaves the wings floating in space, but places the AMT where it normally goes on the ESS speakers. Since active crossing allows me to manipulate the delay, it is easy to move the wings forward. I surmised that with the wings back on the bass bin, the top of the bass bin truncates the sound moving downward from the drivers.
After initial setup and EQ, I moved the wings forward and reset the timing to match the 6" forward position.
Listening alone makes this an obvious choice. Sound opens up even more and I got a fuller soundstage....the type I originally heard when l first listened to individual AMTs on each speaker.
I am glad you tried this. After reading your post about how you originally had a top and bottom with the wings but did not like it, moving them forward was the first thing that came to mind. I am glad you are finally listening to music!

Can I ask... and perhaps it's already been discussed somewhere in the thread, would a curved face/lens be an option?
When I get my measurement setup dialed in on the straight face lenses, I am planning on experimenting with a curve.
it may take a little while.
