So, besides being able to retrofit these to customers with those speakers... this would enable the creation of an entire new line of speakers.
If so, that's kind of a really big deal.
Let me know when you want me to ship you the walnut Encore cabinets I snagged from Denton so you can work up something for the Encore / have something to play with. I got a pair of birch cabinets from Peter. Do it... Do it...
In theory, you could retrofit this setup into an older N-series speaker, but the crossover would definitely have to change due to how the waveguide changes the response of the tweeter, plus our tweeter performs a bit differently than the older BG units.
Danny and I have talked about bringing back the N-series at some point in the past as a halfway between the X and NX, but we set that idea/plan aside a while ago, but with us working on filling out the new shop, I wanted to build something for use in that space, since we use the N-1 in the current shop.
Cutting new holes on pre-finished cabinets is rather tricky, with a lot to go wrong, it'd be much easier to have Killian get with me to make an Encore-based test cabinet with the N-series holes. (I'm currently working with a custom Bravo cabinet with N-1 holes), I've already suggested a couple tweaks for the final cabinets, and based on the measurements I got along with few other ideas I tested out. The initial design works really well, but the cabinet needed some small tweaks to further improve it's measured. The only way to get "perfect" measurements would be to move the tweeter external into it's own waveguide with fully rounded edges, and move the woofer to the top of the cabinet, like a smaller version of the horn in the link lower down.
Yeah Hobbs, prepare to be overwhelmed... I now have a DIY idea that includes you, your 3D printer, and a pair of Neo tweeters blowing into horns. 
The main issue is we currently only have one printer in house, and it takes roughly 12 hours to print a single waveguide (depending on quality level), which is quite time consuming and would limit how many we can make/sell. We would need to have them mass-produced, which would make for a much better finished product than 3D printed units. The rear cup is less of an issue, the other trick will be sourcing a good material we can supply to fill the back cups, or also having them produced with fill already in place.
We're already considering getting a 2nd printer that should be much faster, but we haven't committed to it just yet.
Printing a massive horn takes forever, not to mention uses a lot of filament, and I'd likely have to print it in two halves.
Plus, the 3D-printed horn only worked "okay", but the CNC cut one was a much better performer overall thanks to its much denser build, really boosting the bottom end without the need for baffle-step compensation.
With a basic 2nd-order slope, I could cross the tweeter as low as 700-800Hz without breaking a sweat, which would be great for pairing with a large high-efficiency woofer.
