Redcatt Redemption is a two way compact speaker.

Redcatt Redemption is a bass-reflex cabinet loudspeaker with drivers of Redcatt .

The kit is delivered with the following drivers:
- a Redcatt 140FCDX4+Redcatt Horn 280 x 210 horn with driver
- a Redcatt 101NPMX8 woofer

The loudspeaker has been developed by Thomas Schmidt.

The crossover consists of:
- a 2nd order high-pass filter (12 dB per octave slope) for the tweeter.
- a 2nd order low-pass filter (12 dB per octave slope) for the woofer.

The frequency response of this speaker is nearly linear.

The decay spectrum is nearly perfect.

At low volume, i.e. 85 dB at 1 m, the nonlinear distortions are below 1,3% above 300 Hz and doesn't exceed 4% at 95 dB at 1 m between 300 and 15000 Hz.

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 Redcatt 140FCDX4+Redcatt Horn 280 x 210 are of type polypropylen (MKP) Clarity-Cap CSA 630 V.

  • ClarityCap CSA capacitor 3.9 μF / 630 Vdc
  • Audaphon MKP CAP Superior 15 μF / 400 Vdc
  • Mundorf baked varnish air core coil BL71, 0.47 mH/0.57 Ohm
  • Mundorf baked varnish air core coil BL140, 2.2 mH/0.46 Ohm
  • Metal-oxide resistor, 10W 4.7 Ohm (yellow-violet-gold)
  • Metal-oxide resistor, 10W 6.8 Ohm (blue-grey-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 10 μF / 160 Vdc
  • 0.7 mm air core coil, 0.56 mH/0.55 Ohm
  • ceramic resistor 10 Ohm/20 Watt

Price per impedance correction for one speaker, to be mounted on a small wooden board.     EUR 9,80 excl. VAT: € 8.24 / $ 8.98

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 / $ 4.31
We recommend one board per kit (2 boards per speaker pair)
