Design & listening
More room for the drivers. The same compact idea.
SAT MK3.3 moves to a slightly larger cabinet than the earlier SAT designs. A 13 cm main driver and 17 cm rear driver are made specially for Microphase by Audax in France.
The MK3.3 version introduced an improved crossover in October 2024. Its tweeter uses an in-house-designed 3D-printed faceplate, while crossover components come from Mundorf, SCR and Dayton Audio.
The art and the science
The design, in detail.
Explore the choices behind SAT MK3.3.
Components chosen for the design.
The published design combines Mundorf, SCR and Dayton Audio crossover components with Linkwitz–Riley phase alignment.
Birch ply and bi-wiring.
The marine-grade plywood cabinet has a clear polyurethane finish and supports bi-wiring.
Measured and listened to
The response is part of the story. Music is the test.
Microphase publishes measurements alongside its product information. Discuss your room and system with Jean-Marie to put the response into listening context.
Emotion is the measure. Engineering is how we get there.
Hover over the measured graph to explore each frequency range.
Sub-bass 20–60 Hz
Felt more than heard. The weight under a kick drum, a pipe organ's pedal notes, the rumble of a synth bass line, the floor of an orchestra.
Kick drum · pipe organ · synth sub · double bass low notes
Bass 60–250 Hz
The engine room. Punch, groove and body live here: the bass guitar's fundamentals, the thump of a kick, the lower notes of cello and piano.
Bass guitar · kick drum · cello · piano left hand · toms
Lower mids 250–500 Hz
Warmth and fullness. The body of an acoustic guitar, the chest of a male voice, the wood in a string section. Too much here sounds muddy; the right amount sounds rich.
Acoustic guitar body · male vocals · viola · French horn
Mids 500 Hz–2 kHz
Where the music lives. Almost every instrument has its core here: vocals, snare, horns, guitars and keys. If the mids are honest, the whole recording makes sense.
Vocals · snare · trumpet · electric guitar · piano
Upper mids 2–4 kHz
Presence and intelligibility. Your ear is at its most sensitive here, so consonants, pick attack and the bite of a horn section come forward. A little goes a long way.
Vocal consonants · guitar attack · violin · saxophone
Presence 4–6 kHz
Clarity and definition. The snap of a drumstick on a rim, the edge of a cymbal, the detail that makes a voice sound close rather than distant.
Cymbal strike · rim shot · vocal sibilance · plucked strings
Brilliance and air 6–20 kHz
Sparkle, shimmer and space. Cymbal decay, a singer's breath, the sense of the room around the performers. This is what makes a recording feel open.
Cymbal shimmer · breath · hi-hat · room ambience
