We have been using the PA 150MK II for a number of years for both live and tracked work, (4 piece Male Vocal Swing group) on their own for small to medium sized venues or as part of a larger setup (sometimes used as bass bins) for large hotel function rooms.
The speakers are light in weight in comparison to other manufactures, but they are by no means light on sound. Fantastic Bass, and pretty decent highs. I was concerned at the time that the HF drivers wouldn't be up to much, believe me they are. Can you get better speakers? sure you can, but at this price, you can afford to keep a couple as spares, these are about the best we have seen.
