I agree with this, I used to have 9.1s for fronts, mas masarap pakinggan yung 9.3.
I've tried the entire Diamond 9 line, and I liked the 9.3 and the 9.6 best (of this bunch). The 9.6 however, only sounds its best with a strong amplifier. The 9.6 needs an amp with a lot of current capacity, because of wild impedance dips and highly negative phase angles. For most HT setups (entry level to midlevel AVR powered), I suggest looking at the 9.3 instead. They're fairly forgiving speakers, and are not very difficult to drive. They do lack absolute LF extension, which the 9.6 delivers. However, in an HT setup, the sub can handle those frequencies. Use thick cables, toe the speakers in, take out the grilles, cross them at around 60Hz, and you'd likely be set (you can handle the EQ-ing and time alignment adjustments, as necessary).
There are also other speaker options out there, and it's always best to hunt around and hear the set that you like best.
