Illuminata 15 BE (Beryllium) is a two way compact speaker.
Illuminata 15 BE (Beryllium) is a closed-cabinet loudspeaker with drivers of Scan Speak .
The kit is delivered with the following drivers:
- a Scan Speak D3004/664000 tweeter
- a Scan Speak 15WU/8741T00 woofer
It is also available with Silk Dome.
The loudspeaker has been developed by Bernd Timmermanns.
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 medium volume, i.e. 90 dB at 1 m, the nonlinear distortions are below 0,5% above 300 Hz.

Kit without cabinet, price per speaker EUR 991,00 excl. VAT: € 832.77 / $ 899.39
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 Scan Speak D3004/664000 are of type polypropylen (MKP) Mundorf MCAP EVO Silver Gold Oil 450 V.

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 14,20 excl. VAT: € 11.93 / $ 12.89
If you prefer to mount the crossover components on a 240 x 165 mm universal PCB instead on wood:
Universal PCB RA240, order no.. str-RA240, price per unit: EUR 8,60 excl. VAT: € 7.23 / $ 7.81
We recommend a half board per kit (one board for a speaker pair)
