PRO18SUB – One Sub. Every Situation.
Home theater that rattles the walls. Parties that start the second it turns on. Tailgates that steal the parking lot. Rooftop sets that carry across the city. Pep rallies that reach the top bleacher. At practice where you can hear the music at the other end zone.
That’s the PRO18SUB experience.
What it actually does for you
- Turns movie nights into something you feel in your chest, not just hear
- Gives house parties and backyard gatherings that evoke comments from your neighbor a few houses down

- Pair it with the optional C1000 battery pack and go completely off-grid, throw that rager in the middle of nowhere or have the loudest tailgate at the party
