Tas is a powerful satellit subwoofer system. It consists of Tas Top and Tas subwoofer

Tas is developed by Daniel Gattig.

Tas contains Celestion horn driver, horn, mids and mid-woofer.

The crossover consists of a 2nd order high-pass filter (12 dB per octave slope) and a 2rd order low-pass filter.

The frequency response is quite flat at an angle of 0 or 15 degree, the harmonic distortion is low (less than 0.3% between 400 and 3000 Hz at 95 dB, 1m). The decay spectrum shows small resonances at 500 and 1000 Hz; apart from that it is nearly without fault.

Kit with high-end crossover

Our high-end version employs Rike Audio oil capacitors, produced in Germany. In the woofer part Clarity cap capacitors are used. A Mundorf varnish air core coil and two copper foil coils replace the standard air core coils. The resistors are of type Mundorf MResist Supreme..

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 8,80 excl. VAT: € 7.39 / $ 8.28

universal PCB

If you prefer to mount the crossover components on a 240 x 165 mm universal PCB instead on wood:
