Summary: Big and Loud the speakers just pump out the volume all night. Being a 3-way design, the vocals sit mostly on the mid-range speaker, which make for clearly heard lyrics. Keyboards sound great through this PA. They are big and heavy. Recommended for permanent or semi installed venues.
Excerpt: I was blown away! Not being used to having a 6.5 in driver for the high mids in the cabinet I was a little nervous about getting these but now that I've used them my mind has certainly changed. These 3 ways boxes are fantastic and very transparent through out the freq spectrum, And when you add subs you now have a four way system!
Excerpt: The sound quality is sufficient to small crouds open door, however these sound better in-door at 80 to 90% your volume. Design and looks are great, easy to connect. However try not to maximize you volume becasue you will reach the max level and the driver will stop for a few seconds and then it will come back playing.
Excerpt: This is a fantastic product. The fidelity of this 3-way system is remarkable. The flexibility of this system for a performer is high, and truly simplifies what I do most often. The majority of the time, I have a Rivera Sedona miked up in one channel, and a vocal mic in the other channel, daisy chained to a second QSC153. Great fidelity, big sound, simple set up. Use quality cables, these QSC's are good enough to reap the benefits.
