Atelier Rullit field coil driver
Hello everyone
I'm seriously considering purchasing a field coil driver from Atelier Rullit.
It appears that Rullit field coil drivers are adaptable through field coil voltage adjustments and that they are not inherently restricted to a certain cabinet. Even though field coils are versatile and flexible I still believe it's paramount to install them in a cabinet accommodates the drivers in the best way possible and a cabinet that suits my room.
Allow me to introduce my listening environment: I reside in an historic manor apartment where my dedicated listening room measures 25 square meters (5 × 5 m) with ceilings approaching 2,7 m in height. I principally enjoy classical and jazz repertoire, ranging from solo recitals to chamber and full orchestral works. As an amateur pianist, I prioritize a natural sound—one that offers holographic depth, dimensionality, and body—while presenting a rich, organically pure tonal palette. Mr. Rullit’s drivers admirably embody these characteristics with their transient speed and natural timbre.
I have read that following cabinets can be relevant and I have allowed for some personal reflections for each choice:
Front loaded horn
This would be a great idea however it seems that in order to get a good result I would need quite large horns and perhaps too large for my living room.
Another thing to think of is that I would probably need an augmented bass solution.
Dipole
A more compact solution that would blend in nicely with my interior however there could be an idea in not putting the exquisite driver in a box.
Resonant cabinets
I don't have any experience with these cabinets and I would probably need a professional cabinet designer (and a larger budget) to facilitate this solution.
Other horn designs
My naivety allows for rather crazy ideas and I thought freely that I could just combine plans of La Scala (Klipsch) as the bass idea with some of the bone white horns from Le Cleac'h. I don't know why but perhaps you can offer your commentary on this solution.
If anyone has experience with this or perhaps have some recommendations for cabinet designers etc., I would highly appreciate it.
I'm not interested in field coil drivers, but for my vintage 8 inch drivers (and a small room like yours) I would consider Oris 250 horns mated with the little Gallo 3 subs (no lower cutoff on the horns and the tight sounding subs extend to 200Hz+). The horns/subs would come in at under $2.5K (new) and you would just have to DIY stands for the horns. You could experiment with various drivers using this setup.

The compact Gallo TR3 subs are "self powered" and would just need to be adjusted (on the back) to the horns. They are a typical powered sub with an onboard crossover network. Two would be required as bass becomes noticeably directional above 60 Hz, or so (one sub per channel located close to or below the horn). Figured it’s a realistic approach considering the room size/budget. I’ve tried the TR1 and TR2 subs with some of my single drivers and they mated/blended quite well crossed over @ 100Hz. Plus the 250 horns are not that large/deep. PS: You need to use the low level inputs on the subs for the crossover frequency adjustment to be active. https://galloacoustics.com/product/tr-3d/
