The kit is delivered with two Monacor SP-12A/32PA subwoofer

The loudspeaker has been developed by Bernd Timmermanns.

The crossover consists of:
two wave traps

The frequency response of this speaker is nearly linear.

The decay spectrum is nearly perfect.

Our kit consists of

  • 2x Monacor SP12A/302PA, mid/bass
  • PE sealing tape, 5x2 mm, 7.5 m

Kit without cabinet, price per speaker   EUR 444,00 excl. VAT: € 373.11 / $ 421.61

For the loudspeaker is additionally required: 1 piece of threaded bar M10 x 1000 mm, 8 pieces of counter sunk screw DIN 7991 M10 x 120 mm, 8 pieces of screw socket M10 x 40 mm.

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 are of type polypropylen (MKP) Mundorf Evo Öl 450 V.
