This is another non-kit answer to your kit question (sorry about that) but I thought it might demonstrate that even a from-scratch project need not be overly daunting or complicated.

I just installed, ten minutes ago in fact, these DIY planar magnetic desktop speakers. I wanted to see how much I could simplify the construction I used in my previous DIY planar magnetic project. The result was quite a simplification! Of course, these speakers are about 2 feet tall instead of 7 feet, made to show their guts, and use a single element for all frequencies above about 200 Hz. A powered sub under the desk fills in the bottom octaves.

I'm a brand new user of the Equalizer APO app but it's great for this application. I have a little 20 watt/channel (into 8 ohms, 40 watts into 4 ohms) amp/DAC that has a usb input (you can see it to the left of the left speaker in the photo). So the speakers are built to play just the computer's output. Using Room Eq Wizard I measured the speakers' outputs, and then imported the compensating filter settings into Equalizer APO. If you look closely you can see the configuration editor on the computer monitor. Works great! I worried about directivity issues but in practice I move my head so little when I'm at the computer that it's really not a problem at all. And the imaging is quite remarkable, with the uber-nearfield listening.

I was inspired by the little desktop Maggies but uninspired by their cost. The most expensive parts of my speakers are the NdFeB magnets. I needed 252 of them. In case you want to price things out, I bought N42 magnets, 1" x 1/4" x 1/8", poled through the thin dimension, from Magnets For Less.

You’re welcome. Give a holler if some aspect of my planar magnetic adventures would be useful in your own quest.

I have been trying to find a schematic of the BG Radia Z-92 crossover( no longer made ) as the Neo 10 would make a nice start on any planar diy project... probably would go with a ribbon tweeter instead of the Neo 3 as a tweeter and 2 Dayton rs180 as the woofers.
