These speakers will do perfectly if you are looking at a 10-75 ppl setup, they can easily play up 50 ppls in a big room, then can run for up to 10 hours at max volume, they have some loose screws, and the plastic protections corners will break easily, bot besides all that, they have huge volume and a normal bass kick, you can force them to play a huge bass kick but they will clip over easily if you are using the bass on them, but if you want to komplement these speakers with a subwoofer (15''/18'') they are great, LOADS of volume for the price, and you wont be dissapointed... but saying all that, they can't play for 12 hours, and they can't play more than 75 ppls up, so these are for home partys only, not for professional dj's :)  using them for my computer with a complementary ibiza 15'' sub, sounds awesome, and has loads of volume and kick for the bucks :) 

awesome speakers do the job perfectly

I have worked with a performer who regularly used these when doing PA events in different places, work excellent with audiences up to 300 people and sound is clear. I am going to buy another set for my own performances as I am pleased with these.

Excellent value for money A+ recommended!
