Timbo-X is a two way compact speaker.

Timbo-X is a bass-reflex cabinet loudspeaker with drivers of Wavecor .

The kit is delivered with the following drivers:
- a Wavecor TW030WA14 tweeter
- a Wavecor WF182CU13 woofer

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

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

The frequency response of this speaker is nearly linear.

The decay spectrum is perfect.

At low volume, i.e. 85 dB at 1 m, the nonlinear distortions are below 0,4% above 500 Hz and doesn't exceed 0,8% at 95 dB at 1 m between 300 and 15000 Hz.

Our kit consists of

  • Wavecor silk dome tweeter TW030WA14, 8 Ohm
  • WF182CU13, Wavecor Mid/Woofer, 8 Ohm, paper cone, BD, phase plug
  • Bass reflex tube HP70 XL, 70x220 mm, black
  • 2x Damping fleece MT Bondum 800 (30 x 50 x 2 cm)
  • 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 black/red
  • 1,5x Pan screws 3.5x17 black, torx, 8 pieces

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 capacitor for the Wavecor TW030WA14 is of type polypropylen (MKP) Clarity-Cap CSA 630 V.

  • ClarityCap PWA capacitor 15 μF; / 160 Vdc
  • ClarityCap CSA capacitor 3.9 μF; / 630 Vdc
  • Mundorf baked varnish air core coil BL71, 3.3 mH/1.75 Ohm
  • Mundorf baked varnish air core coil BL140, 3.9 mH/0.65 Ohm
  • Metal-oxide resistor, 10W 5.6 Ohm (green-blue-gold)
  • Metal-oxide resistor, 10W 6.8 Ohm (blue-grey-gold)
  • Metal-oxide resistor, 10W 22 Ohm (red-red-black)

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).

  • Audaphon MKT CAP 33 μF; / 160 Vdc
  • 0.7 mm air core coil, 0.39 mH/0.49 Ohm
  • ceramic resistor 10 Ohm/20 Watt

Price per impedance correction for one speaker, to be mounted on a small wooden board.     EUR 14,63 excl. VAT: € 12.61 / $ 14.76

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 4,58 excl. VAT: € 3.95 / $ 4.62
We recommend one board per kit (2 boards per speaker pair)
