Waveline 152 MK2 is a two way floorstanding speaker.
Waveline 152 MK2 is a transmission-line loudspeaker with drivers of Audaphon and Wavecor.
The kit is delivered with the following drivers:
- a Audaphon AMT 2i air motion transformer (ribbon-tweeter)
- a Wavecor WF152CU13 midrange / bass driver
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 as shown in the waterfall diagram is exemplary, free of any disturbing resonance.
At 90 dB and 1 m, nonlinear distortions are below 1 % almost everywhere above 200 Hz.

Kit without cabinet, price per speaker EUR 615,00 excl. VAT: € 516.81 / $ 589.16
The high-end kit is delivered with copper foil 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. The capacitors for the tweeter are of type polypropylen (MKP) Mundorf MCAP EVO Silber Gold Öl 450 V.

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).
If you prefer to mount the crossover components on a 140 x 102 mm universal PCB instead on wood:

We recommend two boards per kit (four boards for a speaker pair)
