Nearfield monitors for a small room

OK first this is a Madisound kit, I have known and delt with them since the 1980’s lived 4miles away and worked less than a mile.
Now some quick points.
First 3 K for a kit you have never heard you can’t return is a bit much to take a flyer on.
Tony you have the skills to do all the basic assembly.
Other than looks these are very different from any Amphion although I think Amphion uses SEAS, this is a 3 way coax, personally not a fan of Aluminum Alloy drivers above 120HZ but that’s personal taste.
One worry is that in a dual concentric the cone acts like a horn or wave guide, Aluminum cones are stiff but have all kinds of HF resonances, not a big deal for a standard mid or woofer, but when you use it for HF pattern control your going to use lots of DSP to reduce these.
Not a Hypex fan, but Amps I like DSP and conversion would triple the price.

Here was the deal breaker for me, These are not cheap drivers, but I can’t find a reference to a replacement diaphragm or recone kit for either! Look in DIY playing around with crossovers I’m going to fry a tweeter & maybe a mid, rather not pay $500 for a new driver ( this is why the TAD’s use a copy of the TAD crossover, take a look at TAD 4002 BE diaphragms.

I have a former student with a set of Neumann monitors and they sound quite nice. I'm happy to share when I can.
