Do you have the Rullit prices ?
L.Cao makes this nice 8'' coils for the Chinese market that are all about tube amps, price $1472 not expensive as it include a EL34 coil power supply.

Alot more FCs are appearing.

Expensive to build thou, so one pays a price.

Sonido would be the first i would try. The 6x9 can be had with a FC. A really good PS is needed.

Rullit Silver Lab8s are not that expensive, the Aero are.
Stereophile has a write up on Rullit field coil in Semrad Audio horns at Capital Audio Fest.
Been a Rullit field coil user for 11 years.

Ultimate field coil the 80lb Jensen Super Giant coupled with any number of higher end 2A3, 45, 6L6 supplies, common with antique radios, for a $$ fraction. Don't think this "open baffle" sounds superb ? Think Again !!

Haven’t been here for some time, came across this and yes I have silver lab 8 for past two years. Great single driver speakers.
Didn’t think I would ever change but in discussions with someone interested in aero 8 and I decided to bite the bullet and bought a pair fresh from Oleg. Been using them for a few months now and just another level up from silver lab but then there is a huge difference in price.
