I have owned a Sampson XP308i, which is only 300 watts, but has excellent quality. I began having an issue with it and found out they were no longer being manufactured. So I decided to move up to the XP1000 which had a superior amount of wattage to my little XP308i. But wattage doesn't tell the story for this unit. It is way under powered as it has no more power for volume than my little 300 watt unit. All the Sampson's have the same horn, but the XP1000 has a 10 inch speaker rather than the 8 inch in my smaller PA. But once I got it on a performance, and as a singer, the microphone settings had no treble only bass. So singing with this unit is not so good. The Bluetooth is excellent with its own volume and tone settings. This unit may be very good for speakers who want music playing before their speech or after through the Bluetooth, but if your a professional singer, this unit isn't recommended by me.
