Elde is a two way floorstanding speaker.
Elde is a bass-reflex cabinet loudspeaker with drivers of Morel and Wavecor.
The kit is delivered with the following drivers:
- a Wavecor TW030WA12 tweeter
- a Morel CAW 638 midrange / bass driver
The loudspeaker has been developed by Dennis Frank and Daniel Gattig.
The crossover consists of:
- a first order high-pass filter (6 dB per octave slope) for the tweeter.
- a first order low-pass filter (6 dB per octave slope) for the woofer.
Between 100 Hz and 20000 Hz, the frequency response of this loudspeaker is nearly flat on axis.
The decay spectrum is nearly perfect.
At low volume, i.e. 85 dB at 1 m, the nonlinear distortions are below 0.3% above 400 Hz and doesn't exceed 0.5% at 95 dB at 1 m between 300 and 15000 Hz.

Kit without cabinet, price per speaker EUR 272,00 excl. VAT: € 228.57 / $ 258.29
The high-end kit is delivered with baked varnish air core coils or copper foil 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 tweeter are of type polypropylen (MKP) Clarity-Cap ESA and CSA 630V.

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).
If you prefer to mount the crossover components on a universal PCB instead on wood

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