These speakers have great sound. They are really awesome!

Nice speakers!

Nothing I don't like. Very good overall response. Use with rear surround and front height speakers.

Sound great.

Wonderful full range speakers we use with a Dolby Atmos surround system for television.

Good value speakers for a small system.

Decent speakers for the price.  Not professional but sound pretty good.  Fairly large for a bookshelf speaker.

A lot of potential for excellent sound and performance. 
First, the "simple crossover" consists of only 2 filter capacitors. The woofer if getting full frequency. The "mid range" is actually a mid-tweeter, and has too much output compared to the other drivers. And, there is no sound absorbing stuffing in the box.
However if you are handy, with a few simple mods you will end up with a respectable sounding speaker. First, you can add a 1mh inductor coil in series with the woofer + wire to help reduce upper frequencies to woofer. Be sure to securely glue it down. Next, add a 10ohm 10 watt resistor in series with the + wire to the mid-range  driver to tone it down a little. Then you can cut a 2" hole in back and add a 2" X 5" port tube the help bring out the lows. Finally, add some acoustic stuffing in the box, covering the back and sides loosely.
The end result will be a deeper and more powerful bass, a tad mellower in upper mid's. The entire procedure took me about 3 hours.

only okay as received, but has tremendous potential

Awesome speakers for the price! Fast delivery. Thank You

Love the speakers!

These speakers sound really good.  I put a 8 inch SW with them for a better low end sound.  But they sound good without Sw well worth the money

Good sound

I could go on and on about imaging, timbre, transparency etc. etc. instead do this.(1) Go to your grand piano, (or your friends if you don't own one) raise and prop up the lid. (2) Play any piece you like and remember the sound. (3) Set the volume of your system to match the size of your listening room. (4) That's what they sound like.

NS-6490 That's What They Sound Like

Great sounding speakers, great price and super fast delivery !!  - Thank you !!!

Yamaha bookshelf speakers

These are fantastic speakers for the price range. No, they will not compete with $1000 or $10,000 a pair speakers, but for their class, they're fantastic.  They have clear and crisp sound, good range and power handling.  I'd recommend them to anyone who wants good sound with our breaking the bank. 

Great sound without breaking the bank!

Very nice speakers  for my setup. A theater/ music room . Solid base  goes pretty low 45db So I was able to lower my subs cut off
