From 6 x 9 inch (15 x 23 cm) one gets halfway Bass, the membrane surface is naturally greater than with oval for round speakers. Who has the space, instead 20cm- equal to incorporate these unusual 25cm-parts, should do so.
Mechanics: The price range gives an idea of it, there is no screw and everything seems a bit "easy". The chassis is rigid, however, the protective grille swings inaudible with.
Sound: The first impression at the center position for heights + middle + downs is "topfig" and sound the heights occupied, after adjusting the CD radio there is a good bass (Bassgittarre) or a very good bass (drums). A bass boost and slight "Loudness" bring more pressure, but cost precision in the bass.
For the money you get a Tieftonstarkes 3-way system with good mids and slightly weak highs. The latter at least silky sound and unobtrusive (not so penentrant-pervasive as "JBL" in the price range).
