The NS10s greatest strength was their reproduction of transients and the tight time domain response you get with closed box speakers
Actually, their greatest strength was that, compared to quality studio reference monitors, they sounded like absolute crap. Yamaha's marketing pitch was "if they sound good on this, they'll sound good on anything," as the goal of using them was to give mix engineers something that emulated the low quality home stereo or portable jam box speakers that mere mortals listen to music on.
It doesn't matter if your song sounds killer in a million dollar studio with $5,000 Genelecs if it sounds horrible to the person who actually buys the music and listens to it at home or in their car. In fact, the first generation NS-10s were meant to be home stereo speakers. Once Yamaha got wind that studios were using them, they started marketing subsequent versions as studio reference monitors. To be sure, the only thing they reference is a substandard consumer stereo.
And that was a long time ago. These days most home stereo speakers and car systems sound better than NS-10s. I gleefully sold my NS-10s along with all my guitar amps last month. The guy buying them was ever so enthusiastic about getting "the real thing" (2nd generation, mint condition), as people often buy legends more than sounds. I was even more enthusiastic about getting rid of them.
They were introduced as the modern take on the NS10s, Chris, IIRC...
...though they sound nothing like them!
I would consider this a Good Thing. I rather suspect that the only reason these monitors have white speakers is to make people feel like they're buying "the legendary industry standard." I'm guessing if you put them next to any other modern reference monitor they would hold their own quite well as they're probably designed to be actual studio quality rather than to emulate bad consumer gear.
