WaveBySide 223 is a three way floorstanding speaker.

WaveBySide 223 is a bass-reflex cabinet loudspeaker with drivers of Wavecor .

The kit is delivered with the following drivers:
- a Wavecor TW030WA11 tweeter
- a Wavecor WF182BD09 mids driver
- a Wavecor WF223BD02 woofer

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 band pass consisting of a 2nd order high pass filter (12 dB per octave slope) and a 3rd order low-pass filter (18 dB per octave slope) for the mids-woofer.
- a 2nd order low-pass filter (12 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 medium volume, i.e. 90 dB at 1 m, the nonlinear distortions are below 0,5% above 100 Hz.

An excerpt from the Hobby HiFi review

The price-performance ratio is outstanding - we know ready-made speakers in the five-digit price range, which have no chance in the sound comparison.

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 in series to the tweeter are of type polypropylen (MKP) Clarity-Cap CSA 630 V.

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 16,30 excl. VAT: € 13.70 / $ 14.79

universal PCB

If you prefer to mount the crossover components on a universal PCB instead on wood:
We recommend one board 240 x 165 mm and one board 159 x 127 mm per kit (two boards 240 x 165 mm and two boards 159 x 127 mm for a speaker pair)
