I purchased three SRX815P and two SRX subs for my church. We have been using them for about two months and I could not be happier. I was planning to purchase the PRX series or potentially a different brand but the first time I heard the the SRX series I had to have them even though they were outside...

For concerts at our church (Christian rock). Simply incredible. Completely changed the overall tone, quality, and oomph of the music. The bass is fat and pronounced. It penetrates and surrounds. You could lose dental fillings.

Have 2 of these paired with 2 815s for DJing and I get crystal clear vocals on the mic with plenty of punch on the low end for the music. Couldn't be happier with their performance.

This speaker is huge! Much bigger than I expected. It is about the size of a small dresser, or maybe a TV stand. And it is loud! Wow! I had a lot of fun playing around with this, but it is definitely a big-venue speaker. This will easily fill up a club with good, rich sound.

First, know that this speaker is huge...big like a coffee table. Its also almost 90 lbs. This is perfect for DJ'ing, bands, outdoor shows. Its got serious power. Not for small rooms, you may shatter windows...lol. its more a larger venue type speaker, club, wedding hall places like that.
