The sound is fantastic for small to mid sized venues. We played a club of about 300 and it filled the room, with no noticeable distortion, and they worked effortlessly with the JBL Subs.
For our monitors, we have them set for normal operation, and with the vocal enhance on. Out front, they are set for operation with external subs. Having these switches makes it very easy to tweak the sound without any major EQing.
Ease of Use:
They are very easy to use.
QSC has always made great workhorse products. I have used their power amps for over 25 years.
I have never had a problem with this company. Never needed to contact them, never had anything break down.
This is a little pricy, but more than worth the cost. We will be getting more of them to make an array for the larger venues.
The Wow Factor:
After receiving the QSC K10 2-Way Powered Speakers, we played three gigs. Out front, we use two QSCs with JBL 18" subs, and we use two QSCs each for monitors. The sound was simply amazing. They are super light, and super efficient. Very easy to set up and get our sound.
