Audaphon Alya passive floorstanding loudspeaker from K+T magazine 4/2016

Kit without housing, price per speaker

.

The Alya is a small 2-way high-end floor-standing loudspeaker.

The excellent Audaphon TWS 30/4 is used as the tweeter, which is also very well suited for low crossover frequencies.

The woofers are two Wavecor WF120CU07 with phase plug and very linear frequency response.

The active version was created by the Klang+Ton editorial team.

The crossover consists of a 3rd order high pass (18 dB / octave) for the tweeter.

A voltage divider adjusts the level to the woofers.

The woofers are controlled by a 2nd order low pass.

The frequency response of the loudspeaker is very linear.

The decay spectrum is almost error-free, apart from a few artifacts.

The nonlinear distortions at low volumes (85 dB, 1 m) are below 0.3% in the audible range above 300 Hz and remain below 0.6% in this range even at (95 dB, 1 m).

Technical data:

• Impedance: 4 Ohm
