Elbe is a high end two way on wall speaker for stereo and home cinema applications.

Elbe is a speaker for on wall, or in wall mounting. Elbe is perfect for mounting next to a flat tv, or behind a acoustically transparent projection screen. Because of the very high quality of the chassis and the high efficiency there is no unfulfilled wishes in sound. The 8 Ohms impedance (minimum 6,4 Ohm @ 240 Hz) allowed to use the most exist amplifiers, especially home cinema amplifiers mostly assumes a minimum impedance of 6 Ohm for each speaker.

Elbe is a bass-reflex cabinet loudspeaker with drivers of Audaphon and Accuton.

The kit is delivered with the following drivers:
- a Audaphon AMT 1i tweeter
- two Accuton C173-11-191E woofers

The loudspeaker has been developed by Daniel Gattig and Dennis Frank.

The crossover consists of:
- a 2nd order high-pass filter (12 dB per octave slope) for the tweeter.
- a first order low-pass filter (6 dB per octave slope) for the woofesr.

The frequency response of this speaker is very linear. The decay spectrum is perfect. At low volume, i.e. 85 dB at 1 m, the nonlinear distortions are below 0.5% above 500 Hz and doesn't exceed 0.6% at 95 dB at 1 m between 500 and 20000 Hz. That is very good.

Our kit consists of

  • 2x Accuton/Thiel C173-11-191 mids/woofer, one unit
  • Audaphon AMT-1i
  • Damping fleece MT Bondum 800 (30 x 50 x 2 cm)
  • Damping Sonofil 100 x 35 cm for 20 litres
  • Female banana jacks, red and black
  • 2m Speaker cable 2x1.5 mm2 black/red
  • 1,5x Pan screws 4x20 black, 8 pieces

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 250 V.

Impedance correction

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 11,50 excl. VAT: € 9.66 / $ 10.34

universal PCB

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 / $ 4.23
We recommend one board per kit (2 boards per speaker pair)
