HiFi Mini PA 6/2, Shelf speaker   as in Hobby Hifi 5/2014

Technical data
- impedance: 4 Ohm
- sensivity (2,83V/1m): 90 dB
- size (HxWxD): 320 x 200 x 280 mm
- frequency range (-8dB): 50 - 30000 Hz
- crossover frequency(s): 2500 Hz
- speaker type: bass reflex

HiFi-Mini-PA 6/2 is designed by Bernd Timmermanns. It is a compact speaker cabinet that contains a Monacor img stage line horn and a mids bass. A bassreflex enclosure design has been used.

The crossover consists of third-order filters for woofer and horn tweeter. In parallel to the woofer an absorption curcuit is used to suppress unwanted resonances.

The frequency response of the speaker-system is nearly flat; the decay spectrum is very good.

  • Mundorf baked varnish air core coil BL71, 0.33 mH/0.48 Ohm
  • Mundorf baked varnish air core coil BL140, 0.33 mH/0.15 Ohm
  • Mundorf baked varnish air core coil BL140, 0.68 mH/0.23 Ohm
  • Metal-oxide resistor, 5W 0.82 Ohm 5% [grey-red-silver]
  • 3x Metal-oxide resistor, 10W 4.7 Ohm [yellow-violet-gold]
  • Metal-oxide resistor, 10W 6.8 Ohm [blue-grey-gold]

Kit with high-end-crossover without cabinet, price per speaker EUR 199,00 excl. VAT: € 167.23 / $ 192.31

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).

  • Mundorf, electrolytic capacitor, unetched, 33uF / 70 Vdc
  • Audaphon air core coil L7, 0.10 mH/0.27 Ohm
  • 3x Metal-oxide resistor, 10W 22 Ohm [red-red-black]


Price per impedance correction for one speaker, to be mounted on a small wooden board.   EUR 11,50 excl. VAT: € 9.66 / $ 11.11

universal PCB

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 / $ 4.93
We recommend one board per kit (two boards for a speaker pair)
