Description

The SB Acoustics SB26ADC-C000-4 is a 1″ (26 mm) aluminum dome tweeter designed to deliver crisp, detailed highs with a touch of metallic sparkle, all while maintaining smooth frequency response and low distortion. It’s an excellent option for those who prefer a more analytical and revealing top end compared to soft domes.

🧠 Why Ceramic?

Ceramic domes are essentially hard-coated metal domes that offer the rigidity and transient speed of aluminum, but with better internal damping and reduced breakup artifacts. You get the detail of metal without the ringing or edginess.


Key Strengths

  • Ultra-clean highs – no smearing or harshness, even at high volumes

  • Low distortion across the treble band

  • Very low resonance allows easy crossover matching

  • High sensitivity (91 dB) makes it great for passive and active systems

  • More refined than aluminum tweeters, smoother top-end behavior


🛠️ Crossover Tips

  • Recommended crossover point: 2.0–2.5 kHz
    (Can go slightly lower with 4th-order slopes)

  • Matches well with:

    • SB15CRC30-4 / SB17CRC35-4 (ceramic cone woofers – perfect tonal match)

    • Satori MW16TX-4 (Textreme carbon cone – high-end builds)

    • Any clean, fast midrange driver in the 5″–7″ class
