I troll facebook alot because it works out to sea pretty good. I see so much hate on DD even when the one defending the brand always shows proof how DD is winning everything world wide even this year. I'm not one to say DD is the best there is but its been VERY good to me. I cant think of anyone that builds subs like DD does so they are going to cost more. I would say Sundown is a runner up but I have never seen a sundown woofer so versitle, maybe the older Zs? It seems now Jacob is designing for that niche market. When it comes to amps nobody is making that kind of power in that small footprint on 12v. DD may not be for you or your wallet but why hate or deny when the proof is everywhere for so many years?
