BlieSMa T34A-4 Aluminium-Magnesium Dome Tweeter (Pair)

£615.60 inc VAT

The Bliesma T34A-$ is an exceptional Aluminium-Magnesium tweeter. It really is a game changer for tweeters, with it’s 34mm dome, 3mm excursion, wide dispersion and extremely linear frequency response it’s an easy to use driver that can be used safely down to around 1.3kHz. That makes it a driver without parallel. This driver opens up the possibilities to use higher efficiency more dynamic 8 inch woofers in partnership instead of the usual 6+1 and designs will follow on these pages for you to build. Even though the driver has great lower frequency  response it still has an exceptional high frequency response too, better than a lot of smaller tweeters, linear out past 25 kHz with the first break up mode out to 30 kHz.

Features

  • 34 mm aluminium-magnesium alloy dome with variable thickness for 27 kHz first breakup mode
  • Extremely low moving mass for better transient response and higher efficiency
  • Fully saturated neodymium motor with copper sleeve for low non linear and modulation distortion
  • 3 mm linear excursion (P-P) and large vent channel for undistorted low frequency operation
  • Narrow surround for less “soft dome” coloration
  • Flush mounted surround and rear mounted magnet system for flat frequency response and wide off-axis response
  • No ferrofluid for improved dynamics
  • Underhung voice coil wound on titanium former
  • Flexible and lightweight lead wires made in Denmark
  • Thick aluminium powder coated flange
  • Aluminium rear chamber with natural wool damping
  • Extremely wide recommended frequency range 1.3 kHz-35 kHz
