SB Acoustics logo

UK STOCK ITEM

The SB26STWGC-4 is a 26mm soft dome tweeter from SB Acoustics featuring a solid aluminium horn loaded faceplate / waveguide for improved air coupling and efficiency resulting in a high output of 93dB.

Key Features:

  • Copper capped pole piece for reduced voice coil inductance and minimum phase
  • Non-reflective rear chamber with optimised damping for improved dynamics
  • Flow optimised vented pole piece for optimum coupling to rear chamber
  • Fine weave soft fabric dome for smooth frequency response
  • Saturation controlled motor system for low distortion
  • CCAW voice coil for low moving mass
  • Long life silver lead wires
  • Low resonance frequency

Basic parameters:

Resonant frequency (fs) 780 Hz Nominal impedance (Zn) 4 Ω
Effective diaphragm diameter 26mm DC resistance (Re) 3.2 Ω
Ferrofluid ? Y/N Yes
Max power handling 120 W
Recommended crossover 2.6kHz/12dB Faceplate diameter 100mm
Sensitivity (2.83V/1m) 93dB Cutout hole diameter 84mm

Good tweeter - but...

I've bought a pair of these for new 2-way project..
It sounds really good for dome tweeter, but as always there is a catch.
Unfortunately it proofed to be useless for crossing at recommended 2.6KHz.
Unlike datasheet frequency response, in the real life both of these tweeters
just keep rising from about 4.5KHz all the way down to Fs.
12dB/oct crossover at 2.6KHz just manages to flatten the response.
And I've tried both Linkwitz and Butterworth.
If you want to use this one, it needs crossing at 5KHz or higher so only good
for 3-way systems..
For now I've gone for something else. And these are going back to the box for next project..

Thankyou for your review Maros!
