About Mach 9
With nine wide-range drivers working in perfect harmony, the Mach 9 is the ultimate expression of Grandinote’s crossover-free philosophy. No filters, no compromises—just music in its purest form.
By eliminating every reactive component, the Mach 9 delivers flawless impedance linearity, lightning speed, and extraordinary coherence. Its mechanical driver design ensures breathtaking clarity, deep natural bass, and an expansive three-dimensional stage.
Refined Italian engineering meets uncompromising musical truth: the Mach 9 isn’t just a loudspeaker, it’s a luxury instrument that brings you closer to the soul of music.
About S.R.T.
The Mach 9 is the pinnacle of Grandinote’s pursuit of pure, crossover-less sound. After years of experimentation, we created our own mechanically treated drivers—eliminating break-up without sacrificing musicality. This innovation allows the signal to remain completely free of electronic filters, preserving coherence, speed, and natural timbre.
Housed in our exclusive Semi Resonance Tube (S.R.T.) cabinet, the Mach 9 delivers bass that is impossibly deep, tight, and agile, unlike any reflex or transmission line design. Combined with silky highs and effortless spatiality, the result is a loudspeaker of extraordinary refinement—a true luxury instrument that brings music to life with unmatched realism and emotion.
