Libertas is a two way floorstanding speaker.
Libertas is a bass-reflex cabinet loudspeaker with drivers of SEAS and Wavecor.
The kit is delivered with the following drivers: - a Seas TWS27-6 + Visaton WG 148 R tweeter - two Wavecor WF146WA05 woofers
The loudspeaker has been developed by Dennis Frank and Daniel Gattig.
The crossover consists of: - a 2nd order high-pass filter (12 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.
The frequency response of this speaker is perfectly linear.
The decay spectrum is perfect.
At low volume, i.e. 85 dB at 1 m, the nonlinear distortions are below 0,6% above 300 Hz and doesn't exceed 0,8% at 95 dB at 1 m between 300 and 15000 Hz.
"In the listening room, the Libertas presents itself from its best side: the two 13-centimetre woofers create a bass as dynamic as a large paper cone and the tweeter matches t them dynamically. The clean crossover area between the drivers pays off in the shape of a stable and precise spatial image, while the tonality hardly changes even at angles - but you can adjust the intensity of the high-frequency range. The tonal balance is absolutely on-point and can inspire friends of all music genres, because all the qualities of a htop-notch loudspeaker are offered here at a more than fair price."
"Sound-wise and technically well-designed speaker, pretty to look at and absolutely inexpensive."

Kit without cabinet, price per speaker EUR 351,00 excl. VAT: € 294.96 / $ 303.81
Price for a pair of custom speakers of any color EUR 2801,00 excl. VAT: € 2353.78 / $ 2424.39
The high-end kit is delivered with baked varnish air core coils 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 Seas TWS27-6 + Visaton WG 148 R are of type polypropylen (MKP) Mundorf MCAP EVO Öl 450 V.
Kit with high-end-crossover without cabinet, price per speaker EUR 415,00 excl. VAT: € 348.74 / $ 359.20
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 13,10 excl. VAT: € 11.01 / $ 11.34
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 / $ 4.07 We recommend one board per kit (2 boards per speaker pair)
