Studio 10 is a monitor speaker with a monacor SP-310CX PA coaxial speaker and high sensitivity.The speaker was developed by journal Klang+Ton.

The crossover consists of a first order high-pass filter (6 dB per octave slope) for the tweeter and a 3rd order low-pass filter for the woofer.

The frequency response of this speaker is linear. The decay spectrum is nearly perfect. At low volume, i.e. 85 dB at 1 m, the nonlinear distortions are not higher than 0.5% between 300 Hz and 10 000 Hz and doesn't exceed 2% at 95 dB at 1 m.

Our kit consists of

  • Monacor SP-310CX
  • 4x Damping fleece MT Bondum 800 (30 x 50 x 2 cm)
  • 0,5x PE sealing tape, 5x2 mm, 7.5 m
  • 2x Damping Sonofil 100 x 35 cm for 20 litres
  • Binding Post PK31, gold plated (one pair, red and black)
  • 2m Speaker cable 2x2.5 mm2, transparent
  • Allen wood screws, black, 5x30 mm, 8 pieces

Kit without cabinet, price per speaker   EUR 278,00 excl. VAT: € 233.61 / $ 273.33

Kit with high-end crossover

The high-end kit is delivered with baked varnish air core coils 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. All capacitors are of type MKP (polypropylen). In series to the tweeter a high quality Clarity-Cap capacitor of type ESA is delivered.

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).


Price per impedance correction for one speaker, to be mounted on a small wooden board.     EUR 18,80 excl. VAT: € 15.80 / $ 18.48

universal PCBs

If you prefer to mount the crossover components on a universal PCB instead on wood
PCB 220x155 mm, order no. I-8805002, price per unit:   EUR 11,70 excl. VAT: € 9.83 / $ 11.50
We recommend one board per kit (two boards for a speaker pair)
