Summary: I have to agree with most everyone's opinion that these do sound wonderful, yet I'm extremely disappointed that after a couple of months use the sub is popping at the least amount of bass. Never played it that loud or treated these things any differently than many other systems I've owned, yet these are the first to have a popping, distorted bass. What a shame! They use to sound great.
Summary: I really like Altec Lansing. I have their inMotion iM7 and have been really happy with that product. Altec Lansing inMotion iM7 Portable Audio System for iPod 3G, 4G, 5G, mini, and nano (1G) It was my satisfaction with that product that drove me to this purchase. I purchased the FX4021 as an alternative to the iM7 which has been serving as a simple stereo setup in our family room. I wanted something small that I could hook up to our iPod for decent sounding music source.
