The goal of many transmissionline designs is to have the typical bass but avoiding the inherent high frequency shortcomings
of this type of loudspeaker. The main problem is a phase shift in the tops causing exaggerations and cancellations depending on frequency.
The Fuzzy Transmissionline is a new concept by Bernd Timmermanns.
The Fuzzy Transmissionline consists of one transmissionline tube
that shows many but small directional changes. The lower frequencies hardly notice the obstacles since the wavelength of lower
frequencies is longer than the dimensions of the directional changes, allowing the bass to travel through the tube without
much interference; the speaker performs like a transmissionline. Due to their shorter wavelength the high frequencies are
blocked by the numerous turns; the negative characteristics of a transmissionline are almost entirely eliminated.
There is another positive aspect: the construction requirements remain modest, simply because four small rectangular
wooden boards are used to assemble the tube (pictured below right).
The speaker is equipped with an Audaphon TWS 25/6 tweeter showing &quoT;according to Hobby HiFi lab results&quoT; an extremely
flat frequency response between 2 and 20 kHz (91 dB +/-1.5 dB).
In the recent MK2 version the tweeter has been replaced by Seas TWS 27-6. TWS 27-6 is without ferrofluid to reduce damping.
For bass a Mission CP 168 is being used; hence the name Transmissionline.
Please note: our standard kit contains already some components listed in the high-end suggestion of Hobby HiFi – the metal oxide resistors (MOX) and the MKP capacitor in series to the tweeter.
