Ducon TML (also called Grünanlage) is a slim 2 way transmission line, floorstanding speaker with Tangband drivers in d'Appolito arrangement.

Drivers used are the Tangband W4-657 SC mid / bass driver and the Tangband 28-847 S with 28 mm fabric dome.

The affordable price really needs to be pointed out:
A transmission line loudspeaker with D'Appolito arrangement for considerably less than 100 EUR!

Review in K+T 3/2005:
..."Over the entire frequency range from 50 Hz to 20 kHz everything is present. The high frequencies are unobtrusive, the quality is phenomenal taking the price of the Tangband tweeter into consideration. We had to really applaud the performance of the speaker, but then the reproduction of applause was authentic. Three-dimensionality was not spectacular, but balanced - what more do you want? "Analogue" instruments like saxophone, oboe or cello are so realistic as if they were playing in the listening room. And over and above that at 75 EUR for three drivers! Even more convincing than the tweeter is the W4. Drum rolls are produced in a relaxed and unforced manner; and the bass drum has got the right size, the listener doesn't miss anything."...
