Omnes Audio SideKick-L 3.5 is a two way compact speaker.

SideKick-L 3.5 is a loudspeaker with drivers of Omnes Audio and Tang Band. Passive radiators provide deep bass.

The kit is delivered with the following drivers:
- a Omnes Audio BB 3.5 full range driver
- a Tang Band W6-1139 SIF woofer

The loudspeaker has been developed by Baur Akustik.

The crossover consists of:
- a 3rd order high-pass filter (18 dB per octave slope) for the full range driver.
- a 2nd order low-pass filter (12 dB per octave slope) for the woofer.

The frequency response of this speaker is nearly linear.

The decay spectrum (waterfall spectrum) shows a decelerated swing-out behaviour in the mid-range.

At low volume, i.e. 85 dB at 1 m, the nonlinear distortions are below 0.7% above 500 Hz and doesn't exceed 1.3% at 95 dB at 1 m between 300 and 15000 Hz.

Kit with high-end crossover

The high-end kit is delivered with baked varnish air core coils for minimizing microphonic effects. - The current flow through the coil creates a magnetic field which sets the reel of wire in motion. This motion induces a voltage in the coil which adds itself to the signal. The stiffer the reel of wire is, the less the signal will be altered. The capacitors for the Omnes Audio BB 3.5 are of type polypropylen (MKP) Clarity-Cap PWA 250 V.

  • ClarityCap PWA capacitor 33 μF / 250 Vdc
  • ClarityCap PWA capacitor 47 μF / 250 Vdc
  • Audaphon MKP CAP Superior 6.8 μF / 400 Vdc
