Alya is an small high-end 2 way floorstanding speaker.

Alya is an small high-end 2 way floorstanding speaker. The kit is delivered with tweeter Audaphon TWS 30/4. This tweeter is also perfect for applications with deep crossover frequency. Two Wavecor woofers WF120CU07 with phase-plug and very linear frequency response are used for the bass range.

Alya passiv has been developed by Daniel Gattig and Dennis Frank. The active version has been developed by the team of journal Klang+Ton.

The crossover consists of a 3rd order high-pass filter (18 dB per octave slope) for the tweeter. A voltage divider reduces the volume to that of the woofers. The woofers are connected to a 2nd order (12 dB per octave slope) low pass filter.

The frequency response of this speaker a very linear. The decay spectrum is nearly perfect. At low volume, i.e. 85 dB at 1 m, the nonlinear distortions are not higher than 0.3% between 300 Hz and 14000 Hz and doesn't exceed 0.6% at 95 dB at 1 m.

Kit with high-end crossover

The high-end kit is delivered with a baked varnish air 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. All capacitors are of type Clarity Cap ESA 250V. The resistors for the tweeter are Mundorf Mresist Supreme.

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 14,60 excl. VAT: € 12.27 / $ 13.25

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 / $ 4.27
We recommend one board per kit (2 boards per speaker pair)
