Beaky, I have the 10 inch (2AA) and the 12 inch (4AA) FBT's and never had a problem yet. People have come up to me and stated that the sound is terrific. I have used them to play with the band having the voices, keyboards, guitar and sax coming through the 2AA's without distortion. Also, I use them for the small DJ gigs up to 100 people. They are light and sound clear. I use the 4AA for bigger jobs. One more item with the controls on the speaker. Always keep the GAIN at 0 or 10 o'clock. The manuals will also recommend it. The volume I keep at 3 o'clock. Check it out when you get them and good luck.
