Shinjitsu Classic SA12 — CP750ND (First-Run)
We’ve seen renewed demand for a classic loudspeaker—large-format woofer and true horn - voiced warm, punchy, and at life-like scale. Working with industry pros, long-time clients, and trusted reviewers, we built the SA12 to deliver room-filling music with easy dynamics and low fatigue.
The foundation is Beyma’s high-sensitivity 12BR70 treated-paper woofer: robust bass with a smooth, well-behaved roll-off right where a great horn wants to take over. For the top, we pair the renowned CP750ND compression driver with Beyma’s large-format TD460N constant-directivity horn.
Why this combo? The CP750ND’s titanium diaphragm is bonded to a polymer surround, damping high-frequency breakup for detail without glare. The TD460N’s carefully shaped entry (the well-known “duck-bill” vane) preserves extension and even coverage to the top octave. Together, the pro-grade 12″ plus extended-range large horn deliver scale and immediacy few speakers match at this price.
How it sounds
- Room-filling scale — life-size images and effortless swing at sane watts.
- Warm, punchy bass — 12BR70 loads the room without bloat; tight start/stop.
- Coherent mids — low, steep crossover keeps voices in one “driver’s voice.”
- Smooth top end — polymer-surround CP750ND gives sparkle without splash.
