Aluminata 130/2 KE is a two way compact speaker.

Aluminata 130/2 KE is a bass-reflex cabinet loudspeaker with drivers of Visaton .

The kit is delivered with the following drivers:
- a Visaton KE 25 SC, 8 Ohm tweeter
- two Visaton AL 130, 8 Ohm woofers

The loudspeaker has been developed by Bernd Timmermanns.

The crossover consists of:
- a 3rd order high-pass filter (18 dB per octave slope) for the tweeter.
- a 3rd order low-pass filter (18 dB per octave slope) for the woofer.

The frequency response of this speaker is perfectly linear.

The decay spectrum is perfect.

At medium volume, i.e. 90 dB at 1 m, the nonlinear distortions are below 0,2% above 200 Hz.

Our kit consists of

  • Visaton KE 25 SC, 8 Ohm
  • 2x Visaton woofer AL 130, 8 Ohm
  • 1,5x Damping fleece MT Bondum 800 (30 x 50 x 2 cm)

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 Visaton KE 25 SC, 8 Ohm are of type polypropylen (MKP) Mundorf MCAP EVO Silver Gold Oil 450 V.

Impedance correction for 40W amplifier

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 47 μF / 160 Vdc
  • ceramic resistor 6.8 Ohm/20 Watt

Price per impedance correction for one speaker, to be mounted on a small wooden board.     EUR 13,90 excl. VAT: € 11.68 / $ 12.26

Impedance correction for any amplifier

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 47 μF / 160 Vdc
  • 4x ceramic resistor 6.8 Ohm/20 Watt

Price per impedance correction for one speaker, to be mounted on a small wooden board.     EUR 19,00 excl. VAT: € 15.97 / $ 16.76

universal PCB

If you prefer to mount the crossover components on a 159 x 127 mm universal PCB instead on wood:
