TBTL-W6, Floorstanding   as in Hobby Hifi 5/2014

Technical data
- impedance: 4 Ohm
- sensivity (2,83V/1m): 82 dB
- size (HxWxD): 1000 x 210 x 420 mm
- frequency range (-8dB): 26 - 40000 Hz
- crossover frequency(s): 180, 3300 Hz
- speaker type: transmission line

TBTL-W6 is designed by Bernd Timmermanns. It is a 3-way column speaker in a bass-reflex cabinet.

Benefits include the perfectly matched frequency range. The disadvantage: a low efficiency of 82 dB (2,83V, 1m).

The crossover consists of second-order filters for bass and mids. For the tweeter a third order high pass is used.

The frequency response of the speaker-system is very flat; the decay spectrum is very good.

Kit with high-end crossover

The kit with high-end crossover contains Mundorf silver gold capacitors in series to the tweeter. In series to the fullrange speaker two capacitors in parallel (15 uF foil capacitor and 68 uF electrolytic capacitor) instead of an electrolytical capacitor is used. Except for coil no. 1 (L1) instead of standard coils only baked varnish coils are used.

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).

  • Mundorf, electrolytic capacitor, unetched, 82uF / 50 Vdc
  • Mundorf air core coil L71, 0.022 mH
  • 3x Metal-oxide resistor, 10W 15 Ohm [brown-green-black]


Price per impedance correction for one speaker, to be mounted on a small wooden board.   EUR 14,60 excl. VAT: € 12.27 / $ 13.86

universal PCB

If you prefer to mount the crossover components on a 240 x 165 mm universal PCB instead on wood:
Universal PCB RA240, order no.. I-2767, price per unit: EUR 7,60 excl. VAT: € 6.39 / $ 7.22
We recommend one board per kit (two boards for a speaker pair)
