I have no idea if that will even run on a modern OS. It has not been modified for 20 years. I tried to update it to VB.Net but the changes were so great that it never happened.
Soundeasy can do this, although I'm not sure how many drivers can be included.

Here's some pics of the midranges. They're the Gento woofers that Parts Express used to sell for $2. I think Speaker Addict on eBay may still sell them. Same woofers that Bill Waslo used in his first Synergy project. He used four, I'm using two. Basically I need to leave room on the horn for the woofers. Plus, this thing will be a boombox with a 100W amp, nothing TOO crazy.
I always want to try something similar, do you have drawing on what the final box will look like?

It's just a plywood box with a Synergy Horn mounted to it. Really basic stuff.
The dimensions that you use will depend on whether you want to take it on an airline, and what dimensions they'll allow. I scaled mine for Southwest Airlines, they're fairly generous. United and Delta are dicks about this, and WILL charge you $50 if your item is even half an inch larger than allowed.

Here's the frequency response and distortion of the compression driver on the waveguide. This is a JBL 2408H-1. You can buy it here : JBL 2408H-1 Compression Driver 365011-001X - Speaker Exchange
It's basically an improved version of the BMS 4540ND. I'm using it for this project because it's light and because I only have one 🙂 (If I had two I might save them for a different project.)
I'm a little surprised that it's rolling off this much; here's the polars of the exact same compression driver on a JBL PT waveguide.
Here's the frequency response of one midrange on the waveguide, along with the compression driver. The level of the midrange has been raised by 20 (yes 20) decibels. Those small midranges are convenient but they are not efficient.
Here's the same measurement, but this time showing one and *two* midranges. I'm surprised the additional mid is adding this much output, because the wiring is series. IE, you'd expect it would be about the same. Must have something to do with my amp? Dunno.
Here's a frequency and distortion measurement of the waveguide with two midranges on it.
To me, it looks like the midranges need a highpass around 500Hz and the tweeter needs a highpass of about 1500Hz.
The latest iteration of this soundbar has turned out to be impossible, unfortunately.
Here's what happened:
In most of my Synergy Horn projects, I tend to use small compression drivers, and this project was no exception. Since most of my projects are usually for a car, I typically 3D print my waveguides and I use a very narrow angle, like this:
In this project, I used a commercial waveguide that has a much wider angle:
The problem with this setup is that the small compression drivers can't play low enough on a waveguide that's this large. I tried pushing it, and the distortion just goes through the roof. And it's not possible to push the midranges up any further, the coupling chamber in front of the mids is just rolling them off too much.
So... That's about it! Game over.
