It's always best to match rms rating of cabinet to your amplifier power rating.
Key Qualities
This cabinet has very good low end response and crisp highs. Like the dj12.1, this cabinet is fairly acurate, yet it handles a good amount of power. This is probably the most used cabinet we have, It works good in so many applications and holds up well. People seem to have nothing but good things to say about it.
Applications
One man band, mid size DJ gigs, weddings, studio monitors, churches and good for full pa use, minus the drum kit.
