Budget Classic 3-way Discussion Thread

Anybody give thought to the Dayton MX10 or MX12? As long as sensitivity is high enough, they dig deep in smaller volumes.
We kind of abandoned Dayton drivers as they are not nearly as inexpensive in Europe as they are in the US. An example is the Dayton DSA315-8 and the Scan-speak Discovery 26W. In the US the prices are $110 and $210 but in Europe they are something like €160 and €170.
 
...I also think that a 12" woofer might be overly ambitious for a speaker at this price point. A 10" woofer allows a smaller cabinet, and a higher crossover point to the mid. The cabinet will be a significant portion of the overall cost of this kind of project, and a higher crossover point allows more midrange options (including cheaper midranges), and smaller L's and C's in the crossover.
I have thought about this a few times, partly because there seem to be a LOT more options if we considered a 10" driver. But, me personally, a 10" 3-way is not interesting as they are pretty common. Not necessarily the Monkey Coffin format (sorry!!) but if I wanted an inexpensive 10" 3-way I'd just build the Tarkus. [Not literally true, I wouldn't build anything because I am listening to a 10" standmount 3-way right now.]
 
The bigger 5" SB15NBAC30 would be a better choice to mate with the 12" and it would still be ok crossing to a 19mm tweeter at >3khz. Not much $ difference. At Solen it's $85 vs $90 (or close to that).
I am partial to 5" midranges, but for no scientific reason.

One thing I have considered - at least when thinking about what I would build for myself - is using a 3D printed waveguide. Because (1) this will greatly help with directivity matching and (2) AugerPro has done such amazing work to have some many readily available. Anyone else have a strong preference for or against using 3D printed waveguides in the design?

One vote against a printed wave-guide. It creates a potential availability issue for some other parts of the world.

I have never built someone else's design.

I might build one pair.

Might have a couple spare SBA 12"s. Not the SB34NRX75-6 but the pricier SB34SWNRX-S75-6. Depending on how the "Possible monitor/monkey box/coffin group project" turns out. 😉

Already have 4 SLS 10s that will be turned into 1-box Tarkus. Or variant of whatever evolves here in this thread.
 
I am interested in this build, it might not happen right a way as I am working a build for my brother and a 2-way project but the Econo-Monkey does interest me. 10" or 12" versions, I am undecided. But I lean towards a higher sensitivity design if possible over say 85dB sensitivity.
3D printing a waveguide is something like a lot of others here is something I am interested in, but not ready to go there yet. I just surfed the PE page, 14% off sale calls to me but I can wait until the next sale to pull the trigger for this build.
 
You can get 3D prints pretty cheap from China. If you are in the US, I'd probably print some if people need them. Maybe they'd be hard to print in rural Rwanda, but I still bet they wouldn't be too hard to get.

The reason I am in favor, is that a weakness of the traditional wide-baffle classic three way is poor directivity compared to what we can achieve these days.
 
Not yelling, I don't know why the picture is huge. I'm OK either way if anyone can get the wave-guide. How costly are they? How much work to cut the box for one? The look of the speaker may be important. If we find more than three people who want to build it, we can maybe ask. This tweeter is not pretty, but I have a pair. Limited use so far. I believe Wolf_teeth has heard these before, and could comment on performance. I've mostly just used one in a center channel, but I plan to build some mains with them.

I would cross them at 3k for this project, but currently they are crossed at 2k in my center channel.

I wouldn't mind a waveguide tweeter either. SB26STWGC, Morel CAT328 or the H26TG are good options for me. If I had to I would do a 3D printed WG. The 3D printed WG I purchased for a GRS PT6822 was not aesthetically to my liking (rough). Just my preference, not a game stopper.

I checked with customer service. If you order the Peerless 12", it will be May before it comes in. You can cancel the order in May if you decide to.
