Summary: OK. I've had these (2 sets + centre channel) for about 10 years. I have 2 systems (don't use the centre channel anymore) Tonight I just bought a pair of used orbs thinking of downsizing. I can immediately tell the difference. Even with a sub. I guess I've been spoiled all these years. I'm sticking with the the p150's. If you are paying what the advertised price is TODAY ($50 - $100) you are getting a great deal.
Summary: I'm a longtime Infinity fan. i bought my first set in the 70's and those speakers are still going strong. The reason I bought that first pair was because I listened to them side by side with speakers from other name manufacturers in the same price range. The difference amazed me. Crips, TIGHT sound reproduction. Infinity speakers consistently offer crisp, clear, distinctive, and true sound reproduction.
Summary: These are great bookshelf speakers. I've owned larger JBL speakers,and these sound better, with increased clarity, and bass! The price was fantastic, and shipping was quick. I would highly recommend these speakers.
Summary: Despite its small size, this speaker provides a rather full presentation with a clear, not shrill sound. Even full orchestra classical music sounds good. Caution: Many suppliers sell this as a single speaker, not in the usual pair. I purchased online and all was well until I saw it at my local Circuit City for $20.00 less per pair. However, they will easily please you; they compare well with some I have in the $300. - $500. range.
Summary: These are recommended components in the high end underground Stereophile magazine, which rates speakers up to $100,000. It takes a pretty good speaker to even make the list albeit these are class E, with class A speakers being the state of the art. Surely one cannot expect deep bass since the bass driver is so small, but the midrange is so sweet and the high end is superb.
