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.

Field coils can be some of the best drivers out there, look as Voxativ's top models all field coils. but in my experience, they require lots of money to get right. one of the biggest issues we have had is getting the field coil power supply noiseless. especially hi sensitivity speakers like horns. I have too close friends who run field coils, and they are both now moving away from them due to power supply issues.

 

 If you have the money to do it right and get the power supply that is very good, then go for it some of the best sound I’ve heard. If you’re on a budget, I would not recommend it. Just a quality power supply for a field coil is going to cost what a top-notch amp will, and you need two.

 

Both my friends did the field coils in open baffles by the way, they both moved away from cabinets due to the cabinet sound. Once you go OB its hard to go back to a cabinet, i.e. once you hear a cabinet you can’t unhear it.  Granted you have the room for them and I think you do.
