SEAS E0101-04 (T29D002) 'Dark Diamond'

26‑mm Diamond Dome Tweeter.

The SEAS Excel T29D002 “Dark Diamond” features a 26‑mm pure diamond dome that behaves as a perfect piston up to 45 kHz, ensuring exceptionally clean and uncolored high‑frequency reproduction.

The patented HEXADYM magnet system, built from six radially magnetized neodymium blocks, provides efficient ventilation and eliminates resonant cavities behind the dome, surround, and voice coil. A precisely machined copper sleeve reduces nonlinear and modulation distortion, while the titanium voice‑coil former maintains stability under high thermal load.

The aluminum front flange with mild horn loading ensures a smooth frequency response, while the acrylic rear chamber with internal scattering surfaces minimizes reflections for improved dynamic accuracy.

• Nominal impedance [Zn]: 4 Ω
• Recommended frequency range: 1500…40000 Hz
• Resonance frequency [fs]: 510 Hz
• Sensitivity [2.83 V⁄1m]: 90 dB
