Due to some recent life events, I no longer have the means to make a DIY speaker myself. However, I would still very much like to make a speaker, or at the very least, participate in it's design and construction. So I need a builder.
Yes you will be compensated accordingly.
I want to build a set of active MTM monitors with side firing subwoofers. Traditional materials are always an option, but am open to other methods like 3d printing (provided cost be about the same to a little extra). I would also like to be able to put these on stands/tripods/etc.
Please contact me via the ad here and we can discuss the details further.

That's a great idea thank you! 🙂
I'm in the eastern PA area closer to Philadelphia.
Have a look here, this is Troel Gravesen, he’s an experienced professional builder and he’s got many designs that could potentially fit your requirements. I’ve build the ATS-4 and my friends have build other designs from him. They all sound superb!

You need to buy the crossover from him and then you get the schematic, the cabinet build is always on the web page.
There’s also some nice kits from CSS which have been reviewed to sound very good.

Just an idea!

Use one on each side so that they are push-push. makes a big difference.
Big Wood Studio was doing good cabinet work, but issues with a place to put his CNC has him not shipping anything at this time.
There is a cabinet builder in Ontario that is still going. A thread (or at least a mention) somewhere here.

I design them (sometimes with Scott’s help), but building has long passed.

Consider whether flat packs would work for you. All you need is a bit of space, some tape, maybe some clamps, and some glue. If you aren't comfortable assembling them, there is a good chance that buying flat packs and paying someone to assemble them will be cheaper than having a cabinet maker start from scratch. For that , somebody local who advertises on fb marketplace as doing furniture restoration could probably handle it.
Also think hard about your plan and do some research. Putting a "subwoofer" into the same stand mounted box is generally going to mean super low efficiency, not much bass extension, and a ton of compromises. And still having to buy stands. The laws of physics grant pretty big advantages to floorstanding speaker or mains plus subs.
Separately, anything other than a well-vetted existing design will either be MUCH more expensive because you'll have to pay one of the few people who has the proper space, time, gear, and experience to design something or not nearly as good. Some of us love novelty, but know that you could easily spend a few grand to end up with something that isn't nearly as good as an established <$500 design.
If you like MTMs, I'd look hard at GR X-MTMs. The X-CS if you really want a separate sub. The Dayton TriTrix is extremely affordable in both floorstanding and monitor versions. If your budget is bigger, Madisound has a few MTM designs with cabinet plans that are detailed enough for a professional cabinet builder even if they aren't experienced with speakers.

I've assembled far more complex than a speaker I assure you. I just no longer have access to all my tools and stuff so I'm not able to build it myself.
In a push-push configuration (placing the woofers magnet to magnet) you are able to cancel out the forces that would ordinarily create resonances in a cabinet. There are a lot of monitor designs that use this principle including a lot of KEF stuff. KEF even takes it a step further by combining both speakers together and merging the center pole piece. They have a bunch of papers on the subject if you're interested.
I also can't use floorstanders at the moment. Monitors suit my needs far better.
The drivers themselves I have in mind are already above that price point as it is. No <$500 design I know of uses purifi drivers 😛
I am familiar with those designs. However, they do not reach the spec I desire in terms of distortion figures.
The first commercial application was in the 104 II
I learned about the technique earlier, but didn’t try it till after,

Actually one of the more interesting modern designs I've found is from Paradigm. Rather than have force canceling drivers, they only have the driver on one side, and a weighted load on the other, but with the spider etc. still there.The first commercial application was in the 104 II

Have a look at this. If I was going to buy a kit this would be it. I may DIY it with an electronic crossover.

Oh I just remembered that speaker Hardware makes flat packs. They might be able to help you. I don't know if they do one off builds but it would be worth asking about.

See, this is why I like this place: lots of creative ideas 🙂
That's an excellent idea. Thanks!
I am happy to put the bug in your ear. I am sure there are others. Perhaps some closer to you.
Good luck with it
