Elias X2 SW275 Top Passiv is a two way wall-mounted speaker.
Elias X2 SW275 Top Passiv is a bass-reflex cabinet loudspeaker with drivers of Audaphon and Wavecor.
It is available in different versions:
The kit is delivered with the following drivers:
- a Audaphon APR 1.0 ribbon-tweeter
- two Wavecor WF182CU13 woofers
The loudspeaker has been developed by Dennis Frank and Daniel Gattig.
The crossover consists of:
- a 3rd order high-pass filter (18 dB per octave slope) for the tweeter.
- 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 0,3% above 500 Hz and doesn't exceed 0,5% at 95 dB at 1 m between 500 and 20000 Hz.

Kit without cabinet, price per speaker EUR 939,00 excl. VAT: € 789.08 / $ 954.78
Price for a pair of custom speakers of any color EUR 5953,00 excl. VAT: € 5002.52 / $ 6053.05
The high-end kit is delivered with baked varnish 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 Audaphon APR 1.0 are of type polypropylen (MKP) Clarity-Cap CSA 630 V.
Kit with high-end-crossover without cabinet, price per speaker EUR 1003,00 excl. VAT: € 842.86 / $ 1019.86
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 8,30 excl. VAT: € 6.97 / $ 8.44
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 / $ 12.00
We recommend one board per kit (2 boards per speaker pair)
