Tiber is a three way on wall center speaker with a mounting depth of 130 mm, perfect for mounting underneath, or above a flat tv, or a screen.

To the Tiber center we can recomment the following speakers for a home cinema setup.:
Frontspeakers:Zaurak, Omikron, Duhr, Rana, Rhone
Rearspeakers:Duhr, Rhone, Rana
Subwoofers:Don, Don 2, Don MK2

Tiber is a closed-cabinet loudspeaker with drivers of Wavecor .

The kit is delivered with the following drivers:
- a Wavecor TW030WA12 tweeter
- a Wavecor WF120CU08 mids driver
- two Wavecor WF223BD01 woofers

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 3rd order low-pass filter (18 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 0.5% above 400 Hz and doesn't exceed 1.2% at 95 dB at 1 m between 300 and 15000 Hz.

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 tweeter are of type polypropylen (MKP) Clarity-Cap ESA 250V.
