Yamaha NS-IC400 4" Full-Range In-Ceiling Speakers (White, Pair)

Discreet architectural audio with full-range voicing, high-frequency extension, and a flush, paint-ready finish

Designed to disappear into bright, modern ceilings while preserving musical detail, the NS-IC400 pair delivers full-range in-ceiling performance from a compact 4" platform. Yamaha’s double-layer cone construction and ridge-shaped aluminum center cap are engineered to smooth response across the spectrum, while a grain-finished acoustic baffle with a spiral dispersion pattern supports natural room fill. A magnetic, paintable grille enables clean installs with zero visible screw heads, and a sealed back cover helps protect the driver assembly from dust and moisture in real-world ceiling environments.

✔ Pair for stereo zones ✔ 30W RMS / 90W peak handling ✔ 95 Hz–40 kHz (-10 dB) response ✔ Magnetic paintable grilles ✔ 8Ω impedance • 85 dB sensitivity ✔ Slim, flush-mount profile

Clean Architectural Integration with Natural, Full-Range Tonality

The NS-IC400 is optimized for discreet background music and distributed-audio deployments where visual impact must be minimal and intelligibility must remain high. A stair-like surround profile and aluminum center cap geometry help smooth transitions from low to high frequencies, while the spiral-pattern baffle supports more even dispersion. For long-term reliability, the sealed back cover protects key components from common ceiling contaminants such as dust and ambient moisture.

Core Capabilities

🎶

4" Double-Layer Cone for Natural Tonality in Compact Ceilings

Double-layer cone construction helps maintain controlled behavior through the driver’s operating range, supporting more natural timbre for voice and music. The compact form factor is ideal for smaller rooms, hallways, and distributed zones where refined, low-visual-impact audio is the priority.

ConfigurationFull-range in-ceiling
Impedance8 Ω
Sensitivity85 dB

Response Smoothing Geometry for Cleaner Low-to-High Transition

A ridge-shaped aluminum center cap paired with a stair-like surround profile is engineered to smooth frequency response from low to high, helping reduce unevenness in the presence region for more consistent listening across typical in-room seating.

Spiral-Pattern Acoustic Baffle for Natural Dispersion

The grain-finished baffle with a spiral dispersion pattern supports more even room fill—helping reduce “hot spots” directly under the speaker and improving perceived balance as you move through the space.
