Summary: I am very pleasantly surprised by the quality of these speakers. I have had them for one month now, and am enjoying them more all the time. They replaced some vintage JBL LX-44s in my 2.1 music listening system, and I couldn't be happier. I had previously installed (and returned) Def Tech BP8Bs, but didn't like the 'bipolar' sound so I went back to my trusty JBLs. I was originally driving them with a Yamaha RX-V867 (high end consumer grade AV amp).
Summary: Excellent speakers Yamaha has what I call a "flat" sound. Clarity and authenticity of each note seems to be the goal with Yamaha. Lots of other speaker systems embellish the bass, largely because many music lovers enjoy a stronger bass register in their music. I notice this each time I get into a shared vehicle at work. The tonal adjustments are invariably set to heavy bass before I set them back to neutral or slight treble increase.
Summary: In short, these speakers are an incredible value. I Craigslisted a pair of these from a moving-sale (best way to get the best deals btw). I only paid $100 for the pair...which came with a crappy 1,000 Watt RCA receiver, queen mattress, and a mountain bike. After hooking these up to my 20 something years old Technics SA-160 receiver, the sound was so good it inspired me to look up specs... lots of specs.
Summary: I bought these speakers because Yamaha has a great reputation in making great musical and sound products. However, these speakers were great dissapointment to me because they did not sound good. The speakers lack transient response resulting in decreased sound accuracy especially on low audible frequencies. Not like sealed enclosures, they lack the punch and deep bass tone response.
Summary: Somewhat of a biased review because I've only used these paired with a subwoofer. I actually bought these over the NS-777's to save money because I knew my lower frequency range would be covered my my subwoofer and A/V receiver's built-in tuning algorithms. Having said that, these speakers are excellent for the price. I wouldn't consider any other floorstanding speakers until the +$800 range.
Summary: I am going to keep this simple. These are the best speakers I have ever owned!!! Especially for the pice! 2 woofers, 1 tweeter and 1 mid range driver on each tower!, I have a top of the line onkyo receiver and These speakers rock the house with loud and clear, crips sound!! One day I realized my subwoofer wasn't even connected. That's when I realizes that I didn't even need the subwoofer with these tower speaker. I Never even reconnected that subwoffer again lol.
