Summary: This is a excellent main speaker. I would rate it a 4.5 ebay does not allow that. It takes a lot of power to drive. I currently use 150 W monoblocks. The highs are clean and crisp. Midrage is excellent. Bass is good, but not great. It does not go down to 35 Hz like it says in the specs. The fall off starts at 70 Hz. That is where my preamp a D2v has set the cut off point. It lost about 3 db for every 20 Hz below 70 according to the graph.
