I know the subject of pa and speakers has come up a zillion times, but I'm looking for a lightweight (under 30 lbs) speaker. Good fidelity is a must, since I usually use a Bose L1 or Barbetta Sona 32. I'm not interested in any the computer speaker systems, nothing against them, but I'm only looking for a single powered speaker for small venues (up to 80 people). Any suggestions appreciated. Thanks.
