Really, you couldn't be more wrong. The W7 was basically the first low distortion, high linearity, high output driver in the market. The entire purpose of it's design was to improve BL linearity and reduce distortion while also improving output capabilities by increasing cone area and maintaining a high Xmax (which aside from shear output, the benefits of high displacement capabilities are also a benefit from a "sound quality" perspective as well). Really, it's pretty telling that the design is nearly a decade old now and it's still in the top tier of high performance offerings on the market. You might say "Nonsense! I've heard the subs in my brother's Dakota and it didn't sound good at all!".....and that very well might be the case. But that's not a fault of the driver. Chances are, it was probably a fault of the installation, enclosure, tuning and/or setup and settings. Which makes your listening experience rather meaningless as a point of comparison. Of course it's possible (but unlikely) that the setup, installation and tuning was perfect in your brothers setup. It's also possible (and more likely), that you simply don't enjoy the sound of a lower distortion, linear driver. Your subjective definition of "good sound" might simply be different than what the W7 offers. But that's a difference in subjective preference, not a difference or deficit in "sound quality". But again, since this is based completely on subjective opinion, it's rather meaningless as a point of comparison. I would find it hard to believe someone could spend the time, thought and expense to design a driver like the W7 with all of it's unique and innovative features without being in love with audio. It pushed the envelope of performance and innovation a decade ago, and is still holding it's own a decade later. Also, keep in mind JL Audio got it's start as a mail order speaker business. They were essentially the equivalent of today's "underground" (internet) brands. They just happened to do it extremely well and as a result have grown and experienced a lot of success over time. That really doesn't make any sense. Every business is trying to grow ? I would say JL took that idea to a new level when they designed and released the W7.
