SB Acoustics ARA Kit is a two way compact speaker.
SB Acoustics ARA Kit is a bass-reflex cabinet loudspeaker with drivers of SB Acoustics .
The kit is delivered with the following drivers:
- a SB Acoustics Satori TW29R-B tweeter
- a SB Acoustics Satori MW16P-4 woofer
The loudspeaker has been developed by SB Acoustics and Bernd Timmermanns.
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 crossover frequency of the SB Acoustics crossover is 4000 Hz.
The frequency response of this speaker is nearly linear.
The decay spectrum as shown in the waterfall diagram is exemplary, free of any disturbing resonance.
At medium volume, i.e. 90 dB at 1 m, the nonlinear distortions are below 0,6% above 300 Hz.

Kit without cabinet, price per speaker EUR 394,00 excl. VAT: € 331.09 / $ 400.62
The high-end kit is delivered with baked varnish air core coils and CFC coils on important parts of the crossover 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 SB Acoustics Satori TW29R-B are of type polypropylen (MKP) Mundorf Mcap Supreme EVO ÖL.

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).
If you prefer to mount the crossover components on a 159 x 127 mm universal PCB instead on wood:
Universal PCB RA160, order no.. I-2766, price per unit: EUR 5,10 excl. VAT: € 4.29 / $ 5.19
We recommend one board per kit (two boards for a speaker pair)
