If you are wanting the best, then look no further! I have tried a range of Subs over the past 10 years and the DS18 Helion is by far the best 15 inch Subwoofer I have ever used. It packs quality, sound, style, and of course exceptional bass and sub frequencies that will make anyone who you drive past jealous of you, no matter what you are driving. As soon as I heard just how good this sounded in my car, I was hooked.
