Quick Question to any ; Kharma DB-7's owners.....

I hope all is well with everyone and I just would like to know how the base presentation is with these speakers ? I understand that they are a 2.5 design but the many reviews I have read have indicated that the bass on them is very good. I have a medium sized living room and these would fit in there very well at 100 lbs. However, I am also looking at the DB-9's but they are a much bigger and heavier speaker at 130 lbs. I guess the main question is on the DB-7's is ; can they play rock and roll that will sound realistic and true to the source for 2.5 design ? Thank you in advance.
