Elias X2 W182 SW223 is a three way wall-mounted speaker.
Elias X2 W182 SW223 is a closed-cabinet loudspeaker with drivers of Audaphon and Wavecor.
The kit is delivered with the following drivers:
- a Audaphon APR 1.0 tweeter
- two Wavecor WF182CU13 mids driver
- two Wavecor WF223BD02 woofer
The loudspeaker has been developed by Dennis Frank and Daniel Gattig.
The crossover consists of:
- a 2nd order high-pass filter (12 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 low volume, i.e. 85 dB at 1 m, the nonlinear distortions are below 0.1% above 500 Hz and doesn't exceed 0.3% at 95 dB at 1 m between 300 Hz and 7000 Hz. That is quite splendid.

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 mids woofer are of type polypropylen (MKP) Clarity-Cap.

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 universal PCB instead on wood
PCB 220x155 mm, order no. I-8805002, price per unit: EUR 11,80 excl. VAT: € 9.92 / $ 11.11
We recommend one board per kit (2 boards per speaker pair)
