>> .. The dual driver clearly has its strengths in the bass reproduction. It is very precise, detailed and fast. The good three dB more compared to the SPRING (when the two frequency responses at 1 kHz are superimposed) are very beneficial to the bass. The bass retains its very good technical characteristics, but gets more authority in the subrange and a fuller punch. This allows it to provide sufficient level to any genre without ever overdriving or overshadowing other areas...
... Basically, I like the mids of the SUMMER almost even better than those of the SPRING, which can sometimes seem a bit thinner. However, the prominent trebles of the SUMMER have a say in this respect, which means that I can't always speak of a relaxed listening experience, although the mids alone can't be blamed for this and would have much more potential with reduced trebles, and even really impress with their clarity, resolution and separation....
... Yes, the SUMMER is bright and the peak around 6 kHz is clearly audible, but still mostly bearable. This range gives more presence to some instruments, but also voices, which sometimes seems a bit unnatural, but at the same time provides a distinct transparency. This can cause astonishment, but sometimes unfortunately also leads to lowering the volume to be able to hear the song further... <<
