Lucy Ribbon Grande is a three way wall-mounted speaker that can replace a high-quality floorstanding loudspeaker.
Lucy Ribbon Grande is a bass-reflex cabinet loudspeaker with drivers of Audaphon and Wavecor.
The kit is delivered with the following drivers:
- a Audaphon Neo CD 2.0 ribbon-tweeter
- a Wavecor WF152CU14 mids driver
- a Wavecor WF182BD09 woofer
The loudspeaker has been developed by Dennis Frank and Daniel Gattig.
The crossover consists of:
- a 3rd order high-pass filter (18 dB per octave slope) for the tweeter.
- a band pass consisting of a 2nd order high pass filter (12 dB per octave slope) and a 2nd order low-pass filter (12 dB per octave slope) for the mids-woofer.
- 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 low volume, i.e. 85 dB at 1 m, the nonlinear distortions are below 0.2% above 300 Hz and doesn't exceed 0.5% at 95 dB at 1 m between 600 and 15000 Hz.

Kit without cabinet, price per speaker EUR 665,00 excl. VAT: € 558.82 / $ 558.82
Price for a pair of custom speakers of any color EUR 4590,00 excl. VAT: € 3857.14 / $ 3857.14
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 Audaphon Neo CD 2.0 are of type polypropylen (MKP) Clarity-Cap ESA 250 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 8,30 excl. VAT: € 6.97 / $ 6.97
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 / $ 3.95
We recommend one board per kit (2 boards per speaker pair)
