Lia Mk2   Shelf speaker as in K+T 6/2015

Technical data
  • impedance: 8 Ohm
  • sensivity (2,83V/1m): 83 dB
  • size (HxWxD): 380 x 165 x 270 mm
  • frequency range (-8dB): 42 - 40000 Hz
  • crossover frequency(s): 3500 Hz
  • speaker type: bass reflex

The Lia Mk2 is a high-end 2 way bassreflex loudspeaker with ribbon tweeter and Wavecor woofer. Lia MK2 has been developed by Dennis Frank and Daniel Gattig.

The crossover consists of a 3rd order high-pass filter (18 dB per octave slope) for the tweeter and a 2nd order low-pass filter for the woofer. A parallel RCL drain circuit is smoothing the frequency response of the woofer at about 1000 Hz

The frequency response of this speaker is very linear and has a high bandwidth. The decay spectrum is nearly perfect. At low volume, i.e. 85 dB at 1 m, the nonlinear distortions are lower than 0.5% above 500 Hz and rises not over 1.5% at 95 dB at 1 m .

Our kit consists of

Kit with high-end crossover

The high-end kit comes with two Rike S-Cap capacitors of high quality. The inductances are Mundorf copper foil coils or 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.

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 12,70 excl. VAT: € 10.67 / $ 11.63

universal PCB

If you prefer to mount the crossover components on a 240 x 165 mm universal PCB instead on wood:
Universal PCB RA240, order no.. str-RA240, price per unit:   EUR 8,60 excl. VAT: € 7.23 / $ 7.88
We recommend one plate for one kit (for a pair of speakers you need 2 plates)
