Summary: So i power a set of these using an old integrated pa amplifier pushing 150 watts rms at 8 ohms per channel, now these things are loud but screechy And a bit harsh sounding on the highs. Bass is good though and cabinets could use some extra braceing but overall its really clean. Once the speaker is equalized that is. Good buy. Very loud for only 100w speakers. Update!
Excerpt: I run sound for one of the top Elvis Tribute Artist in the World in 2009. Our tracks are run off a computer. The 3 way speakers help bring out the back ground vocals. I was using 2 way speaker which were too bassy. These speakers are light weight and our perfert for most rooms we play. We also have the GSM1560 for larger rooms which we use when needed. Great sound for the money.
Excerpt: If you want to use for voice only...you may be able to get away with it (if you keep the volume down),however, putting guitar,bass,vocals and drums through it?....save your money. Remember, you get what you pay for.
