Sanken CU-41 Dual Diaphragm Condenser

The Sanken CU-41 is a unique large-diaphragm cardioid condenser designed for absolute sonic honesty. Developed with NHK in the early 1980s, it employs a rare dual-capsule system: a small titanium diaphragm handles the highs while a larger one captures lows and mids, blending into a seamless, phase-coherent signal. This design yields an exceptionally flat response and remarkably consistent tone even off-axis.

Its titanium diaphragms resist humidity and wear, ensuring reliable performance in studios or broadcast environments. With a wide 20 Hz–30 kHz bandwidth, low noise floor, and headroom up to 140 dB SPL, the CU-41 excels on vocals, acoustic instruments, piano, and orchestral sources. Transformer-coupled output adds stability and natural musicality, making it a long-standing favourite for engineers seeking clarity without coloration.

Includes original case and shock mount.
