Description

The SB Acoustics SB29BNC-C000-4 is a 29 mm beryllium dome tweeter with a neodymium magnet system and a compact faceplate, making it a high-end performer in a smaller form factor. It’s designed for systems where space is tight but no compromise in sound quality is acceptable.

Features

  • Beryllium dome for non-resonant high frequency extension
  • Copper cap on pole piece for reduced voice coil inductance and minimum phase shift
  • CCAW voice coil for low moving mass
  • Internal pressure equalization and flow resistor for non-resonant coupling of cavities
  • Long life flexible lead wires
  • Inherently shielded neodymium motor system
  • Compact design
  • Low resonance frequency

  • Mechanical Q-factor, Qms 1.36
  • Electrical Q-factor, Qes 1.40
  • Total Q-factor, Qts 0.69
  • Force factor, Bl 2.6 Tm
  • Rated power handling* 80 W
  • Magnetic flux density 1.2 T
  • Magnet weight 31 g
  • Net weight 0.17 kg

* IEC 268-5, high-pass Butterworth, 2600 Hz, 12 dB/oct

✅ What Sets It Apart

  • Beryllium dome = extremely stiff, ultra-light → gives you fast, detailed, distortion-free treble.

  • Compact design (72 mm faceplate) = perfect for tight baffle layouts, MTM, or bookshelf speakers where space is limited.

  • Neodymium motor = smaller size without sacrificing magnetic strength or linearity.

  • Rear acoustic chamber = helps control Fs and enables low crossover points.

🛠️ Crossover Suggestions

  • Recommended crossover point: 1.8–2.5 kHz
    (can go lower with 4th-order filters)

  • Excellent match with:

    • SB15NBAC30-4, SB17CRC35-4, Satori MW16TX-4

    • Any high-quality midwoofer where you want a clean, high-resolution top end
