The K Sub will give you the sound you need for your live set up. I have heard the QSC K Sub in over 25 different situations and venues and I don?t have a single complaint about it except for maybe the fact that it is not priced to sell.

Powerful and good sound quality. Very sturdy and nice wheels. But the control is not good. You can not switch off the base completely.

The K-Sub is the most compact AND powerful sub I've ever used. My band, 7k, recently used them on a 7-week US Tour and used them in every kind of venue imaginable. We also loaded them in and out of every one of those places! They are truly well-designed, reliable, and sound fantastic.
