Technical data
- impedance: 12 Ohm
- sensivity (2,83V/1m): 90 dB
- size (HxWxD): 500 x 318 x 380 mm

Bernd Timmermanns of journal Hobby HiFi presents in time for the coming gardening season, the new model of its HiFi-PA 10/2 loudspeaker. It contains PA loudspeakers de Monacor.
 

The frequency response of the speaker-system is nearly flat. The decay spectrum is well. The most noteworthy fact is that the non-linear distortions remain almost consistently below 0.3% at 90 dB SPL above 100 Hz.
 

Our kit consists of

  
  • Monacor horn and driver MHD-152
  • Monacor mid-woofer SP-10/250PRO
  • Bass reflex tube HP100
  • 2x Damping fleece MT Bondum 800 (30 x 50 x 2 cm)
  • PE sealing tape, 5x2 mm
  • 2x Damping Sonofil 100 x 35 cm for 20 litres
  • Binding Post PK31, gold plated (one pair, red and black)
  • 3m Speaker cable 2x2.5 mm2, transparent
  • Allen wood screws, black, 5x30 mm, 8 pieces
  • Allen wood screws, black, 4X25MM, 8 pieces

Kit without cabinet, price per speaker EUR 298,00 excl. VAT: € 250.42 / $ 287.98

Kit with high-end crossover

The kit with high-end crossover contains three foil capacitors and in series to the loudspeakers Mundorf capacitors of high quality, like a silver/gold/oil capacitor in series to the tweeter.

  • Audaphon MKP CAP Superior 6.8 uF / 400 Vdc
  • Mundorf MCAP EVO 3.3 uF / 450 V
  • Mundorf MCAP EVO 6.8 uF / 450 V
  • Mundorf, electrolytic capacitor, unetched, 100uF / 50 Vdc
  • Mundorf baked varnish air core coil BL71, 0.56 mH/0.64 Ohm
  • Mundorf baked varnish air core coil BL100, 0.47 mH/0.32 Ohm
  • Mundorf baked varnish air core coil BL140, 2.7 mH/0.51 Ohm
  • Metal-oxide resistor, 5W 3.9 Ohm (orange-white-gold)
  • Metal-oxide resistor, 10W 6.8 Ohm (blue-grey-gold)

Kit with high-end-crossover without cabinet, price per speaker EUR 326,00 excl. VAT: € 273.95 / $ 315.04

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).

  • 0.7 mm air core coil, 0.47 mH/0.50 Ohm
  • ceramic resistor 15 Ohm/20 Watt


Price per impedance correction for one speaker, to be mounted on a small wooden board.   EUR 9,15 excl. VAT: € 7.69 / $ 8.84

Important note: The impedance correction is suitable for amplifiers at an output power of 40 Watt or less.
 

 

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)
