I use four Infinity beta's as the satellite speakers in a 7.1 setup (along with 2 Infinity Beta 50s as mains and a C360 center channel). The system is connected to a Onkyo HT-RC260 receiver. Pros - Sound quality is excellent, with great range (down to around 60 Hz, which is far below your ear's ability to hear the sound be passed over to the subwoofer.) I can listen to these speakers for ear shattering special effects all the way down to pianissimo sections of classical music, with quality being maintained at each level. Cons - Not really a con for me - but you should be aware that these speakers are quite large - at about 20 lbs and 14x14x9 inches - they are much larger than you would expect for satellite speakers. If you are an audiophile on a budget who wants great sound - these are perfect. But they may not be for you, if you are looking for a small setup to visually fit into a living/dining room environment.
