So then what about the old T3 TSS. It LOOKED identical to a DD 9500, but it wasn't. I realize not everyone machines their own motors.... nobody does. Sure they all roll out of factories in asia but does that make them the same? I would have to interject that it really doesn't. It might give them the opportunity to perform similarly. A lot of people look and say "hey that's a DD clone" and buy it. It worked for konaki but that motor isn't the same. Based on your inability to state a factory name or give ANYTHING other than blind speculation I have to conclude that you are talking out your ass. Great observation that they look the same. Anything else, you have no clue what you're talking about. I too think DD is too high, but they used pricing to get the market share they want. They are the most sought after brand name for devoted car audio enthusiasts like us. You might buy another brand, but that was because they attempted to emulate DD.
