Note S is a two way compact speaker.
Note S is a bass-reflex cabinet loudspeaker with drivers of Omnes Audio and Tang Band.
The kit is delivered with the following drivers:
- a Omnes Audio AMT 50 air motion transformer (ribbon-tweeter)
- a Tang Band W4-655 woofer
The loudspeaker has been developed by Baur Akustik.
The crossover consists of:
- a 2nd order high-pass filter (12 dB per octave slope) for the tweeter.
- 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 300 Hz and doesn't exceed 1,1% at 95 dB at 1 m between 300 and 15000 Hz.

Kit without cabinet, price per speaker EUR 134,00 excl. VAT: € 112.61 / $ 121.61
The high-end kit is delivered with a baked varnish air core coil 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 capacitor for the Omnes Audio AMT 50 is of type polypropylen (MKP) Clarity-Cap ESA 250 V.

If you want to use a valve amplifier with this speaker an impedance correction should be employed. In this case the component quality is less important; therefore, we offer only one kit (upon request higher quality components are available).
Price per impedance correction for one speaker, to be mounted on a small wooden board. EUR 17,30 excl. VAT: € 14.54 / $ 15.70
If you prefer to mount the crossover components on a 140 x 102 mm universal PCB instead on wood:
Universal PCB RA140, order no.. str-RA140, price per unit: EUR 4,20 excl. VAT: € 3.53 / $ 3.81
We recommend one board per kit (two boards for a speaker pair)
