The Sound of Tradition

SMR (Super-Magnet-Repetition)
Ensures an unsurpassed repetition speed for uprights. Two magnets, which repel each other, are built into a conventional action. So the jack returns more quickly under the hammer but and is ready again for the next keystroke. No wearing off, no maintenance.
Membrator System
Improves the resonance characteristics of the soundboard and leads to the perfection of the typical, transparent Seiler sound.
Tone Volume Stabilizer
Guarantees permanent additional sound volume and projection due to improved elasticity and tension of the soundboard.
