Since I do not have the privilege to compare them and it seems that there are no reviews of the D25 and the newest D28 has someone had a chance to compare those models although the 2.5 and the D25 are not manufactured any longer. I really liked the Response 2.5 and I consider buying the D28. Does the D28 outperform the 2.5? Any answer will be highly appreciated.
There might be more low end with the D28, but its tweeter can't match the Scanspeak in the 2.5. The 2.5 has a rare, distinguishing naturalness and life, much like the finest musical instruments. The D28 is summa cum laude, the 2.5 magna cum laude.
