I have Hertz HSK 165 components all around so 8 speakers total powered by a RF p500.4and they are great speakers. Pretty good bass and very clear tweeters, but they are really bright as well. Not a big deal though. Overall, very good.
Then I have two RF 10'' T1's in a ported box powered by a RF p1000-1bd. Amazing subs. They pound extremely hard, and have good SQ.
Speakers, Subs and Amps are all very good!
