Mariza is a two way floorstanding speaker.

Mariza is a bass-reflex cabinet loudspeaker with drivers of Wavecor .

The kit is delivered with the following drivers:
- a Wavecor TW030WA07 tweeter
- a Wavecor WF168WA02 woofer

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 perfectly 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 0,8% at 95 dB at 1 m between 300 and 15000 Hz.

  • Audaphon MKP CAP Superior 3.9 μF / 400 Vdc
  • Audaphon M core coil M12, 3.3 mH/0.27 0hm
  • Metal-oxide resistor, 10W 4.7 Ohm (yellow-violet-gold)

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 Wavecor TW030WA07 are of type polypropylen (MKP) Clarity-Cap CSA 630 V.

  • ClarityCap CSA capacitor 3.9 μF / 630 Vdc
  • Mundorf H core baked varnish coil BH140, 3.3 mH/0.19 0hm
  • Metal-oxide resistor, 10W 4.7 Ohm (yellow-violet-gold)

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, 0.47 mH/0.50 Ohm
  • ceramic resistor 12 Ohm/20 Watt

Price per impedance correction for one speaker, to be mounted on a small wooden board.     EUR 15,20 excl. VAT: € 12.77 / $ 13.79

universal PCB

If you prefer to mount the crossover components on a universal PCB instead on wood
PCB 150x115 mm, tin plated, price per unit:   EUR 4,70 excl. VAT: € 3.95 / $ 4.27
We recommend a half board per kit (one board for a speaker pair)
