A number of people have emailed me, and asked what I'd sell them for.



I have been stumped, because the quality of the waveguides is all over the map.



I gave it some thought, and here's what I came up with:



If anyone would like to purchase a set of waveguides, they are welcome to. I will have three tiers of pricing:



Tier One: this is the top tier, the best of the best 3D prints. A set of these prints will sell for $199. Included with the price is shipping to anywhere in the 48 states. If you're overseas, I can provide you a shipping quote. Along with the waveguides, I will include four of the midranges.



The waveguides in tier one aren't perfect but they are the best that I can print with my cheap printer. If you want a nearly flawless print, I have uploaded the model to Thingiverse and it can be printed at Shapeways. Last I looked, that was something like $1600 a pair, so this is still a dramatic discount over commercial printers. If you want to print them using a local Makerspace or the like, please do. I am not printing these to make a profit, I am printing these because I <3 Unity horns and I wanted to provide a kit that would be easy to build and affordable.



Here's an example of a "tier one" waveguide; note that there's a bit of warping and some stringing. It's not perfect, but it's as good as I can print:











Tier Two: These are basically the "B Stock" of my waveguides. They are not as good as "Tier One." Tier Two waveguides suffer from some noticeable splitting and warping. Please note that my own speaker is using a Tier Two waveguide. All of the measurements that I've posted are using a waveguide that isn't the best. I've printed about a dozen waveguides, and it took me a few tries to get the process down. So the very speakers that I will be personally listening to are NOT "Tier One." So please don't consider "Tier Two" defective, they're not. They're just not printed as well as Tier One. Most of their issues are cosmetic. I'll sell you a set of "Tier Two" waveguides for $99. Midranges and shipping are included in the lower 48.















The pics above demonstrate the difference between "Tier One" and "Tier Two." The grey waveguide is "Tier Two." It suffers from noticeable splitting and warping.



"Tier Three" is my last option. If you'd like a "Tier Three" waveguide, I'll give it to you for free. (The waveguide only.) The only caveat is that you have to meet me in person. If you want me to ship you a "Tier Three" waveguide, it's $40 for a set, which covers the cost of postage and four midranges. The "Tier Three" waveguides suffer from serious splitting, and in some cases, need to be glued together to function. This tier is basically for people who want to tinker with Unity waveguides. The cost is basically nil. As noted before, this isn't a business, this is a hobby, I just want people to hear how great Unity waveguides can sound. I'd rather give you a waveguide for free than throw it in the trash.







Here is my own personal speaker, the one I've posted measurements from. It's not as good as Tier One, or as poor as Tier Three. It suffers from noticeable splitting and warping, but it didn't crack in half entirely. The reason that the splitting isn't audible or measurable is because I've sealed off the back of the waveguide. I sealed it with Mortite, which deadens the waveguide and makes it airtight. Mortite is readily available at most hardware stores for five dollars. As mentioned in earlier threads, I have a bunch of spare waveguides left over.A number of people have emailed me, and asked what I'd sell them for.I have been stumped, because the quality of the waveguides is all over the map.I gave it some thought, and here's what I came up with:If anyone would like to purchase a set of waveguides, they are welcome to.
