I like Barefoot mm27, but Kii Three have better sound, more controlled, more detailed in Mid + more controlled Low end
I do not have the money to buy a new pair.
I find it easy to build something like Dutch & Dutch 8C

Has anybody tried this?
I have made a 10inch version inspired by the 8C

IMO, first you need to know if you want a clone of those speaker or you are looking for a good (better than what you have) DIY monitor, I haven't read about Barefoots but Kii is totally different story, it uses DSPs to control delay between drivers and also driver placements (2 on rear and on each sides) to control directivity (Cardioid pattern) that 's why it can sound good in different rooms, it has 6 channel dsp and 6 amps on each speaker that's also how it gets high spl and flat respond.
But if you want a good sounding monitor, you should look for something with reasonable sensitivity and very flat frequency respond (speaker shouldn't have any character), since you have experience with filters and EQs I would say go with DSP.
I suggest to do more research (to know what you are looking for, good sounding is not enough) on this and then more experienced guys will help you through.

About the enclosure, Kii Three are 3D Printed?

What do you think about the 3d print case?

Not 3D printed. "The enclosure is constructed in two halves from injection-moulded polyurethane structural ‘foam’ with integral internal bracing and fittings."

Here's the source of the quote above: Kii Audio Three |

Alex, are you sure of the drivers used?

Everybody wants very good speakers but they are expensive, so lot of people think that DIYing them can save tons of money. This can be true, but (and is a big but) only if the design is good. You don't state what is your experience, but from the question I bet you have never designed a speaker before. While you can design a pretty decent speaker without measurement (if you have access to drivers FR and impedance), designing a hi-end speaker involves measurements and the knowledge on how to interpret the results. Starting with a non-conventional 3-way is IMHO foolish. The best you can do is to find a reputable design that you like and build it.

I want monitors with DSP because I do not listen in the anecoic room.
That's not a reason for having DSP. You can design a passive speaker for normal room placement too.

Hi,
One thing about Fusion range from Hypex they do have dsp onboard (which is nice) but if you already have dedicated gear or plan to use a computer based solution, as far as i understand you can't bypass the AD/DA within the amp or rely on the one used by Hypex ( which should be good as i don't see them don't giving nice things to a ncore amp).
Deal breaker for a very clean signal path if you are in the situation given above though.

About diy a studio Monitor, Plasnu advice is wise ( he knows what he is talking about as he run a studio). If you want to use them in a near future just go shopping something better than yours and which is known to work as expected.

If you have time and wish to invest in measurement gear, learn how to use it and how to interpret the measurement, have skills in woodworking and be prepared to do test and prototype, learn about what you want to put emphasize on what you find interesting in the reference you gave and know about your room and how to get the best of it... go that route!
But it won't be as easy as selecting some drivers and build a loosy box and then process it.

If you don't... go shopping for something already proven. You'll save money and time.

.
The Fusionsamps do have digital input through AES, S/PDIF and TosLink, so there's no need to worry about an extra analog to digital conversion.

If you rely on this generation of converters (and want to use the internal dsp).
In studio, gear change as fast as in audiophile or keeners world. What was used 5 years ago may be changed for 'supposed better' tech this year.
One last thing about this imposed choice (which may not be obvious for non pro users) is the lack of wordclock input.
You could still rely on selfclocking of spdif (toslink being spdif) or aes but in complex digital environment (implying a digital desk, a daw, effects or other digital treatments) it is common to have a clock generator using wordclock to distribute it independently of audio stream.

Details i know.
That said i don't question quality of Hypex range of products.
