Conclusion
Alpine's latest iteration of the venerable Type-X sub is further proof that the company is serious about sound. While the improvements over the previous gen may go unseen, they're a definite step in the right direction.
Alpine really has built an outstanding performer in this competitive price range-a musical subwoofer that is capable of turning out some serious SPL. Needless to say, I really enjoyed my time spent auditioning it. Regardless of the music genre, it was one of the most transparent subwoofers I've added into my system, and that goes a long way in terms of long-term listening enjoyment. If you have $500 burning a hole in your pocket, check out this sub.
