Electro-Voice Evolve 90 Subwoofer for Evolve 90 white

The Electro-Voice Evolve 90 is already not a meagre PA system, with its 18-inch woofer and its eight mid/tweeters. But then again, you always have those who want more! More, more, more! And you can! The woofer from that Evolve 90 is also available separately, as that's the product you're looking at now. Just loop it through, and you have another 18-inch sub blowing for you. So it will depend on the situation whether you need it, but if you want to fill a large room, the extra sub is certainly not a bad plan.
