      TROPO-18 // 650 Watts RMS 18 Inch Car Subwoofer
      R.R.
      Low end moisture

      I pride myself in using lower cost components and making it sound amazing! I replaced a Dayton classic with this Tropo 18, I chose the dayton for it's large effective cone mass, I'm not a fan of large surrounds for they require a smaller cone that moves less air at a higher octave I would like the lowest octave I can achieve with my sub. My enclosure is about 4cf sealed, I love the way it sounds it's just fucking wonderful! 🏆

      Seriously impressed

      I bought 6 of these for my 2020 Silverado to go under my back seat firing forward. I ported my box and tuned to 45hz. These things slam for 6.5’s. I couldn’t believe how much bass came in such a small package. They’re extremely musical and play all the notes. If you’re thinking about running these in your application, just do it.
