Loudspeakers, But In A Different Way
Not many manufacturers attempt to build speakers with such a fundamentally different approach as this brand.
Cabinets made from natural slate. Not easy, but the results are spectacular.
About the SN/SL 370AMT
Similar in concept to the 270s, the deal here is the twin mid-bass drivers are upped from 160mm to 180mm. And again the AMT is mounted in between, to get the d'apolito effect. And of course the overall package is bigger, with slightly higher efficiency and a wider bandwith.
As the F&F speakers get bigger, so there is (at variuos transition points up the range – check the specs) a corresponding increase in the thickness of the slate panels used to construct the cabinets. There's more engineering involved, there's more mass, there's more of that vibration killing property of the natural slate. So as well as more of the basic speaker parameters going up each time, there is also an increase in the available amount of acoustic control from these stunning cabinets.

Matching & Setup
Now we are going up in size and performance with the 370s, they are still not particularly large in high-end speaker terms, but with these, we are edging into high-end performance. So they need more space and deserve better quality upstream components. We would say to go for amplification with real transparency and good bass too, but note the 90dB efficiency so these are starting to get really good with valve amplification. That way you get to maximise the considerable step up in perceived bandwith here, with a lot more scale and headroom.
