Technical data
  • impedance: 8 Ohm
  • sensivity (2,83V/1m): 83 dB
  • size (HxWxD): 960 x 190 x 280 mm

  • crossover frequency(s): 3500 Hz
  • speaker type: transmission line

The WaveLine 152 is a slim transmissionline speaker with drivers of high quality from Wavecor and Audaphon. Wavecor WF152CU13 is used for the bass range and air-motion-transformer Audaphon AMT 2i is used for the upper range. Both units are of very high quality.

WaveLine 152 has been developed by Bernd Timmermanns.

We warmly recommend this loudspeaker.

Its crossover consists of a 3rd order high-pass for the tweeter. A resistor as voltage divider in series to the tweeter got a capacitor in parallel to lift the highest frequencies. The woofer is connected to a 2nd order low pass filter. An RCL curcuit in series to the woofer is compensation the baffle step.

The frequency response is absolutely flat on axis between 40 Hz and 30,000 Hz. The decay spectrum (waterfall diagram over frequency) is free of any disturbing resonances (except the typical resonaces of any transmissionline). At 90 dB at 1 m, non-linear distortions remains below 0.3 % almost everywhere above 800 Hz.

Kit without cabinet, price per speaker   - not available

Kit with high-end crossover

The high-end kit contains Mundorf MCAP EVO silver gold oil capacitors for the tweeter. All coils are foil coils for diminishing the microphonics effect. Current flowing through the coil creates a magnetic field which on itself sets the reel of wire in motion. That motion induces a voltage in the coil which adds itself to the original signal.

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 18,00 excl. VAT: € 15.13 / $ 17.39

universal PCB

If you prefer to mount the crossover components on a 140 x 102 mm universal PCB instead on wood:
Universal PCB RA140, order no.. I-2765, price per unit:   EUR 3,70 excl. VAT: € 3.11 / $ 3.58
We recommend two boards per kit (four boards for a speaker pair)
