I use this in my small studio.
Before I did buy mackie C4, they was small and cheap.
As they broke for the 4 time I wanted someting else.
I did look for many other brands and size, before I did see Presonus Eris E5.
Pro
They are cheap, but still very good.
The bas part is forward and it do work good in a small room where the monitors is close to the walls.
Con
it would be better if they was 6" instead, as they are a bit weak.
You need a sub woofer id you want deep bas, as they cant go down that much, even compare to other this size.
The tweeter has a bit of constant noise, but its not to high, so you dont notice it if you dont come close to the tweeters.
But still I do recomending this if you want a pair of good and cheap active monitors.
