What is your opinion of this product?
I now own 4 different sizes of the QSC K-series speakers, the K-Sub, K12, K10 and now 2 K8's. QSC makes an excellent product. The quality of the sound and the output power are great in each cabinet and they are very solidly built, I think they should last many years. They also come with 6-year warranties which is amazing for this kind of product, it shows that they expect their products to hold up for a long time.
