Elias X1-W182 is a 2 way high-end on-wall speaker. The kit provides an air motion tranformer (AMT) and a woofers of very high quality. The AMT is the very linear Air Motion Transformer Audaphon AMT-1i with very low distorsion. The woofer is a Wavecor WF182CU13.

Elias X1-W182 has been developed by Daniel Gattig and Dennis Frank.

The crossover consists of a 2nd order high-pass filter (12 dB per octave slope) for the tweeter. The woofer is connected to a 2nd order low-pass filter (12 dB per octave slope).

Between 40 Hz and 21000 Hz, the frequency response of this loudspeaker is very linear on axis. The decay spectrum is nearly perfect. At low volume, i.e. 85 dB at 1 m, the nonlinear distortions are lower than 0.6% above 400 Hz and below 0.6% at 95 dB at 1 m .

Kit with high-end crossover

The high-end kit is delivered with copper foil and 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. All capacitors are of type polypropylen (MKP) and in series to the tweeter Clarity-Cap MR 630 V are employed.

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 8,85 excl. VAT: € 7.44 / $ 8.63

universal PCBs

If you prefer to mount the crossover components on a universal PCB instead on wood
PCB 150x115 mm, tin plated, price per unit:   EUR 4,70 excl. VAT: € 3.95 / $ 4.58
We recommend one board per kit (2 boards per speaker pair)
