FEMTO
Designed to fulfill unique high-end requirements…
We are about to introduce a newly designed High End Loudspeaker monitor. FEMTO is the natural extension in our product range in terms of output power to the YOCTO. This loudspeaker will maintain the distinctive qualities YOCTO offers in terms of sound stage, precision, resonance free reproduction. Listening sweet spot is not absent like in a YOCTO but minimized due to a low crossover point, a customized High Frequency Driver and a Horn. High frequencies have a precise directivity up to 20 kHz and way more. It is available as biamp system as well as a passive system and is best paired with 2 x TERA. Entirely milled from a block of aluminum the resonances of the cabinet are practically non-existent. FEMTO is a speaker designed to last a lifetime.
FEMTO is entirely designed and manufactured by Lange Loudspeakers SA in Switzerland, including the drive units.
