Now that I have your attention... 🙂
Im surprised it doesnt exist yet
DIYsoundgroup or parts express have the capability to make this happen
It could be shipped as 4 "flat" packed plastic sides and a mouth adaptor that is glued or screwed or bolted together
A celebrity designer could do a passive crossover design with good value drivers from Tymphany, celestion etc
Shipped in a box to your door for a reasonable cost
It would sell like hot cakes

Unfortunately i dont have a spare $10k to afford that one 🙂
Im suggesting a far cheaper diy solution with 4 bolt together sides so that it cab be shipped cost effectively. Plastic rather than fibreglasa horn.

where did you get the 10k price tag from?
i don't think they are priced yet , perhaps you think about the pse-144 ?
these are different.

Setting up a mold for making large plastic pieces is very expensive, more of an investment than is likely to ever get recovered. These things are larger than most would be able or willing to deal with in their homes (except for some of the smaller sized Synergy designs you can find around on this forum), so not likely to sell a huge volume of them.
Using wood panels is about the only chance, and then making a method of attachment gets difficult. Also needs to be done on a CNC which can change the angle of cuts (not just one angle like 90 degrees everywhere). But it is being discussed.

Oops it $5k ish for the pse144
Sorry i didnt check the link to the new diy version
Looks like ive been beaten to the punch
Ill definitely grab a pair
I imagine it shouldnt be crazy expensive to ship over to you guys? Maybe a group buy?

Whatever happened to the 3d print CD exit transition shapes to square walls on the SH?
I was hoping to see more of those but never did.

I CNCed my synergy horn. I don't want to offer flat packs nor wood most of you want to pay for them. It costs on the order of $100 per hour and 1-3 hours per sheet of plywood to machine them. If you just cut part outlines, 1 hour or so of machining. If you cut dadoes and bevels add another two hours. and then you have to pay for plywood and shipping and then perhaps legal fees. (Its the Unity patent that expired; not the Synergy patent)
The only bevels I'm cutting in my final version of the horn are those I have V-bits for. Machining arbitrary angles can be done but it simply takes too long at $100/hr. Far better to just cut the outline on the CNC and then make the jigs to cut the bevels on a table saw. Once you have the jigs, its relatively trivial and the jigs themselves are simple.
Then if you look at BWaslo, XRK971, and others who have Syngerized SEOS and Tractrix waveguides you see polars that are so much better than you could get from a simple conical horn. My recommendation would be to base a Synergy on a SEOS18 or SEOS24 or a K402, if you can find one. They are probably as good as you can get within their size limits.

My cousins own an injection molding company and I talked to them about this. WAY too expensive even with the family discount.
You can make fiberglass molds out of concrete - but you need to make the original form first. 3d printed original?
Your timing is almost uncanny. PSE-144 started as a kit, the numbers surged until we had enough to do a locally manufactured elliptical fibreglass horn. In the process, we left behind some who wanted smaller, cheaper and more DIY. It's been our plan since then to go back and do a kit like that, we only just decided to start working on it recently.
We're doing this as a pre order. There is quite a lot of interest in the US, so we're aiming to make it cost effective to ship.
Correct me if I am wrong, but even horns as large as the SEOS-24 lose pattern control around 400 hz (at best). What is the point of synergising then? Point source behavior? But, at that frequency, our mind can't tell the difference between the sound coming out from the horn versus a woofer placed outside the horn. I would foucs on avoiding floor/ceiling bounce instead and use a large horn horn on top.
No need to convert a SEOS24 into a synergy, depending on how loud you listen, a BMS coax will bring the usable response down to 380-450hz.
Yes, that's 2 of 4 reasons not to drill SEOS)))
Will somebody from forum in US visit http://thesummerslaughtertour.com/ ? 🙂

What sizes do DIY synergies end up at? Mine was only 28" wide. Art Welter's SynTripp is about the same. I can't think of any off hand that were larger. So size isn't the reason not to use a SEOS24.
Cost could well be a reason to use one; except the cost of the waveguide itself argues against it in the first place. But if you have a SEOS24, Syngergizing trades the cost of the coax BMS for the cost of two of those Celestion closed back mids; a savings of over $500 if I recall correctly.
Taking care of boundary reflections is a system design issue. Unless you go for a floor to ceiling corner line array like ra7, you are going to need some room treatments. By the system design you get to choose where and how much.
Outside of a line array, MTM woofers can provide vertical directivity from the crossover between the woofers and the sandwiched Synergy (or SEOS24 w coax BMS CD) down at least an octave, perhaps as much as 2 octaves depending on spacing. That will go a long way towards mitigating floor and ceiling bounce and I think is a good basis for a system design.
