I've been using this combination for the better part of two years as my main system, crossed with a miniDSP.

I've tried everything from 1100-2400hz, and variations of slopes. I ended up slightly asymmetrical, with a 1700 woofer LR4 and a 1750 tweeter LR4, or somewhere close to there.

I can go into detail if you have any specific questions, or if you'd like me to take measurements of any specific crossover on the miniDSP I would be happy to oblige.

Those look nice! I am torn between building a crossover and using a miniDSP. My gut says measure and build a crossover. 1700 does seem to be an area where both drivers would perform, do you like the way they sound? Also, did you try it in a dipole configuration?

My Satori's arrived yesterday, so I will likely have more questions as I get into my build.

The Satori's arrived yesterday, so I am anxious to start building. I'm afraid the process is going to be drawn out though due to competing priorities.

I did start planning my direction today. I'm thinking of going with 10" Schedule 80 PVC pipe for the core of the enclosures. I have already worked with PVC with my current speakers, which are PVC quarter-wave pipes. These would follow the same theme, but would be bass reflex.

I think I might try using the AMTPRO in a dipole configuration. It would be much easier to deal with physically, though I'm not sure if doing so would add to the complexity of the crossover. Time to read up on the trials and tribulations of dipoles.

The AMTPRO-4 SPL curve and polar pattern look challenging to get great sound. If you have an old wood cabinet you might want to knock-out a test design and search for AMTPRO love before you invest in a complicated-$$ construction.

itschris, Excellent construction work on your 2-way cabinet.
How much miniDSP equalization did you use on the AMTPRO-4?
To your ears, how does the AMTPRO-4 compare to a good dome tweeter?

A tall Kii cabinet still looks good

Agreed, I am going to mock these up before going nuts on an enclosure.

I had a heck of a time trying to get a decent sounding crossover when I tried them as a dipole. At that point I was still trying to work things out passively, so maybe I would have done better with the miniDSP. 1700-1750 was chosen because of the best polar response match, and the crossover offset was done for phase alignment. I'm very happy with them here and haven't had the urge to go back and tweak anything.

It should be noted I'm not very experienced with passive crossovers and have only built a couple pairs I'm really proud of. You might have a better chance than I did

Thanks It was constructed inside a college dorm room with hand tools & the PE knock-downs.

I don't have extensive experience with other drivers, but I do regularly listen to the YG Acoustics Hailey 1.2s; I think the AMTs are definitely no slouch, and the quality is in a realm that's different strokes for different folks. They definitely keep pace with the Satori's. I think they're a good step above the RS28A, but my experience is limited beyond that. If I were to go back to the beginning, I don't think I'd change a thing in driver choice. I'm hesitant to give subjective comparisons, but I do think the 3k region is a little heavier/fuller than the Hailey's. The limited vertical dispersion is definitely a plus for me.

WRT equalization, I think it's rather a lot (6db+) and even more near the ~10k peak. As you noted, the SPL curve was challenging; at the crossover point, the AMTs are pretty inefficient and I don't believe there is any attenuation. The polars (non-dipole) looked pretty well behaved to me when I was working on them.

Another interesting point was that in my final measurements I didn't notice much of a drop-off in the top octave. I'm not sure if its because the 3-13k range gets cut so much, or some other factor. At some point I'd like to remeasure without any crossover because I can't find my original files anywhere.

Lastly, the dipole CSD of the AMT wasn't quite as great as when I closed off the back. Unfortunately I never took the time to investigate.

I too found the AMTPRO to lack a bit up top, so what better way to compliment an AMT than with another AMT. I used the little AMTMini from PE. This was done in my 442 speakers, found here:

I crossed it kinda low in the 1K range and never really had any issues. Those took second place at one of PE's annual MWAF gatherings, so yeah, they sound quite nice!

If your amplifier can handle a 5-ohm load, you can experiment in Xsim with the higher efficiency 4-ohm version of the MW19P-4.
Hi Linesource,
Are you maybe aware of any good design combining MW19P (black version) with Satori tweeter? Other than Troels design, I couldn't find anything.

Do a google search for satorique - Lots of interesting German variations on these drivers

Thanks, I know Satorique, but it's based on a MW16, not 19

And with. time I am more and more inclined to wait a bit a build a three way Satori with 23-24 woofer (ported). I do not have enough place for sealed SB29.
