Technical data
  • impedance: 4 Ohm
  • sensivity (2,83V/1m): 93 dB
  • size (HxWxD): 1200 x 200 x 300 mm

  • speaker type: bass reflex

Aarhus 6 dB is a two way floorstanding speaker with a flat filter of 6 dB.

Aarhus 6 dB is a bass-reflex cabinet loudspeaker with drivers of SB Acoustics and ASE/ScanSpeak.

The kit is delivered with the following drivers:
- a SB Acoustics Satori TW29BNWG-4 tweeter
- two ASE/ScanSpeak 18W-8522-G01 woofers

The loudspeaker has been developed by Dennis Frank and Daniel Gattig.

The crossover consists of:
- a first order high-pass filter (6 dB per octave slope) for the tweeter.
- a first order low-pass filter (6 dB per octave slope) for the woofer.

The frequency response of this speaker is nearly linear.

The decay spectrum is perfect.

At low volume, i.e. 85 dB at 1 m, the nonlinear distortions are below 0,4% above 300 Hz and doesn't exceed 0,6% 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 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 TW29BNWG-4 are of type polypropylen (MKP) Mundorf MCAP-Supreme 600 V.

  • Mundorf MCAP Supreme 3.30 μF / 600 V
  • Mundorf copper foil coil CFC14-1.2 mH/0.26Ohm

Impedance correction

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).

  • Audaphon MKT CAP 33 μF / 160 Vdc
  • 0.7 mm air core coil, 0.12 mH/0.29 Ohm
  • ceramic resistor 4.7 Ohm/20 Watt

Price per impedance correction for one speaker, to be mounted on a small wooden board.     EUR 14,50 excl. VAT: € 12.18 / $ 13.16

universal PCB

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)
