Right, the IBMx45 series are made by
Altec Lansing..
Both the IBM345 (3-piece) and IBM545 (5-piece) have powerful, wood-enclosed subwoofers (which can set your fillings rattling, and neighbors complaining), and 5 watt satellites (a little weak, but they sound good). I've listened to the 3-piece IBM345s in both games and music -- very impressive for $30 (available 3-4 weeks ago from OfficeMax). I'd guess the 545s would be even better.
IMO, I suspect this is a solid, booming set of speakers for a great price.
