Alhambra 2 is a two way floorstanding speaker.

Alhambra 2 is a bass-reflex cabinet loudspeaker with drivers of Wavecor .

The kit is delivered with the following drivers:
- three Wavecor FR070WA04 full range driver
- two Wavecor SW182BD04 woofers

The loudspeaker has been developed by Bernd Timmermanns.

The crossover consists of:
- a 2nd order high-pass filter (12 dB per octave slope) for the full range driver.
- a 3rd order low-pass filter (18 dB per octave slope) for the woofer.

The frequency response of this speaker is perfectly linear.

The decay spectrum is nearly perfect.

At medium volume, i.e. 90 dB at 1 m, the nonlinear distortions are below 0,8% above 400 Hz.

Our kit consists of

  • 3x Wavecor Fullrange FR070WA04, 8 Ohm
  • 2x Wavecor Subwoofer SW182BD04, die cast, 8 Ohm
  • 1,5x Damping Sonofil 100 x 35 cm for 20 litres

Kit with high-end crossover

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 Wavecor FR070WA04 are of type polypropylen (MKP) Audaphon 400 V.

universal PCB

For one speaker you need 1 pc. of RA140 (140 x 102 mm) and 1 pc. of RA160 (159 x 127 mm) pcb.

If you prefer to mount the crossover components on a universal PCB instead on wood:
Universal PCB RA140, order no.. str-RA140, price per unit:   EUR 4,20 excl. VAT: € 3.53 / $ 3.85
Universal PCB RA160, order no.. str-RA160, price per unit:   EUR 5,90 excl. VAT: € 4.96 / $ 5.40
We recommend one board (each) per kit (two boards (each) for a speaker pair)
