Luna Long is a two way floorstanding speaker.

Luna Long is a bass-reflex cabinet loudspeaker with drivers of Omnes Audio .

The kit is delivered with the following drivers:
- a Omnes Audio AMT 60.1 air motion transformer (ribbon-tweeter)
- a Omnes Audio MW 6G woofer

The loudspeaker has been developed by Thorsten Fischer.

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

The frequency response of this speaker is nearly linear.

The decay spectrum (waterfall spectrum) shows a decelerated swing-out behaviour in the mid-range.

At low volume, i.e. 85 dB at 1 m, the nonlinear distortions are below 0,8% above 300 Hz and doesn't exceed 1,3% at 95 dB at 1 m between 300 and 15000 Hz.

Our kit consists of

  • Omnes Audio AMT 60.1 (round)
  • Omnes Audio MW 6G
  • Bass reflex tube HP50, 50x145 mm, black
  • Damping Sonofil 100 x 35 cm for 20 litres
  • Binding Post PK31, gold plated (one pair, red and black)
  • 2m Speaker cable 2x1.5 mm2, transparent
  • 1,5x Pan screws 4x20 black, cross recess, 8 pieces
  • Plan for DIY kit

Kit without cabinet, price per speaker   EUR 186,00 excl. VAT: € 156.30 / $ 181.31

Kit with high-end crossover

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 fullrange driver are of type polypropylen (MKP) Clarity-Cap CSA 630 and Audaphon.

Kit with high-end-crossover without cabinet, price per speaker   EUR 223,00 excl. VAT: € 187.39 / $ 217.38

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 / $ 4.58
We recommend one board per kit (2 boards per speaker pair)
