Summary:
i have had thies speakers for over 6years. i have noticed that if you blare rap or hard bass stuff throught the speakers they will start to pull away from the voice coil. In the past year or so i have up graded to a 7.1 suround sound. wich has more power than my old system my new system has 100 and old had 75. i liked the fact that i could blare any thing through these speakers untel i put 100watts to these and started to mess up the woofers. befor i messed them up i could put bass tones through these speakers and they would rattle my room!!! i love the looks and the sound you can get from these speakers they are kick a$$ if you are smart and dont push a bass tone through the speaker

Strengths:
bass, how sweet they look the way they sound

Weaknesses:
dont push bass tones through them like i did lol!!!

dont compare them to klipsh or you top dollar stuff

Summary:
These speakers will sound OK unless you happen to put a different brand of speaker next to them. Then you'll realize these little Yamahas sound like the music is coming out of the bottom of a well. These were my main and only speakers before I upgraded to a decent setup (new Yamaha receiver, Klipsch Synergy speakers). Next to the Klipsch, which cost a little more but are still moderately priced, the Yamaha bookshelf speakers sound terrible. As soon as my Klipsch SS-1 arrive (to complete my setup), these Yamaha speakers are going to the salvation army.

Strengths:
Cheap (100 per pair). Did I mention a low price?

Weaknesses:
The fact that these speakers are 3-way is kind of gimmick.

Summary:
Good product at an excellent price. Not pretentious and no extra dollars for a pretentious name plate. (although Yamaha is up there) Deep accurate base and consistent treble with some knob tweaking. Very good looking speakers that fit with any decor.

Strengths:
Sound/Price ratio

Weaknesses:
a tad light. may not stand up to some really loud rock.

Summary:
These speakers have impressed me greatly. After upgrading from some reasonably good computer speakers, I was impressed with the sound quality. Combined with a 12" subwoofer, they have good response. Their only lacklustre point being the mid - high ranges being slightly too bright. A tweak on my Yamaha's treble control soon fixed this. I listen to jazz, rock, alternative and classical music and the speakers were able to recreate the sounds of these to my liking. I have these set up in my bedroom. It is likely that they would not be sufficient for a home theatre set up, but until then, the price was well worth it.

Strengths:
Good sound balance with a little fiddling of treble and bass controls. Gold plated banana plug compatible speaker wire sockets. Nice finish. Not too large. Good range Lively sound.

Weaknesses:
High frequencies too bright

Summary:
Update review/response to Nicholas Scott: After much listening, I'm wishing I had the budget to upgrade, but I still stand by my recommendation: the 6390s are a good deal for $100 or less (preferably less). Did I say that they were the best in the sub-500 category? Clearly, I did not - and they certainly aren't. The technology in a $400 pair is far superior. However, if you're a broke grad student like me, then you it's not sensible to buy somewhat more expensive speakers (say, $250 Cerwin Vegas) that sound only a little better overall. The Yamahas do sound tinny and relatively unclear, and the crossover is rough (again, I implied as much), but the point is that a poor crossover at 8khz is better than a poor one at 2.5khz, which hits much more often. Do give us all the credit for understanding that these are inexpensive, consumer-grade technology, which in fact makes up the majority of what many hangers-on call hi-end audio. Besides, if we wanted to debate the merits of truly hi-end audio, we'd be talking about $1000+/pair units, which most of us probably couldn't afford and/or couldn't justify. Few dedicated audiophiles would ever think about thinking about NS-6390s.

Strengths:
Value, value, value...for the starving student and more.

Weaknesses:
Excessively bright sound; characteristic, but acceptable-for-its-class lack of clarity.

In the next year, I want to go 5-channel with 4 LothX Ions and a yet-to-be-determined center and sub. Hopefully, I'll upgrade to a pair of Ion bookshelf speakers ($600/pair)before the Fall.
