Three-Way/Four-Driver Bass Reflex Speaker System

Yamaha's NS-555 speaker system has been designed specifically for home theater applications. The floor standing speaker is a bass-reflex design that can be used for main channels and incorporates a pair of 6 1/4" Polymer-Injected Mica Diaphragm (PMD) cone woofers, a 5" midrange cone driver and a 1” aluminum dome tweeter. For improved imaging, the midrange and tweeter utilize Yamaha's exclusive waveguide horns.

Waveguide Horn

Unlike most homes, movie theaters use sound absorbing materials on walls and ceilings. The result is that the sound reaching your ears is the sound wave produced by the speakers rather than reflected off the walls. Yamaha has created wave guides that greatly reduce reflected sound and increase the proportion of directly generated sound waves reaching your ears. The result is a clear and precise sense of sound direction and placement.

Internally Wired with Monster Cable™

Yamaha has chosen to ensure optimum sound quality by internally wiring some of the components with Monster Cable™. This ensures a clean, clear signal from the crossover network to the speaker driver.

Speaker Stands Included

Yamaha's matching speaker stands provides the solid footing necessary for full floor contact, enhanced stability, and minimal vibration resonance. The stands also provide an attractive counterpoint to the cabinet.

Magnetic Shielding

The speaker is magnetically shielded, so it can be placed on a TV or video monitor without degrading the picture via stray magnetic fields.

Bi-Wiring Capability

To further maintain signal purity, Yamaha provides bi-wiring capability for the NS-555 speakers. There are separate +/- terminals for the woofer(s) and other driver(s). The separation reduces modulation distortion and better sound quality.

Performance Enhanced by a Handsome Cabinet

The EF series speakers are enclosed in an Elliptical Form cabinet with a high gloss black piano finish, which provides solid construction with minimal sound diffraction.

New Grill Design

New grill design and grill cloth provide an attractive and acoustically transparent protective cover for the drivers.

Yamaha Factory Refurbished

Buying a Yamaha Factory Refurbished product is a great way to get "as-new" products at a considerable savings. Every product has been thoroughly tested, repaired (if necessary), cleaned and otherwise renewed to original condition. Next it’s repackaged with original accessories included. When you consider that a factory-renewed Yamaha product undergoes such close scrutiny for defects and workmanship, you might actually be buying something that is in many ways better than new. And for your piece of mind and protection, your purchase is covered by a full 1 year parts and labor warranty valid at any authorized Yamaha repair center (you can look-up locations online here or call 714-522-9888)

Yamaha, like all electronics manufactures, receives products returned for various reasons. In 2011 consumers returned 17 billion dollars in electronics globally, of which less than 5% were found to be defective! Once a product has been opened it must be resold as refurbished and can’t be resold as new again. The history and reason why a product was returned is not provided to us, thus we can’t provide any additional details regarding its past. All products are processed by Yamaha certified technicians, where they are fully tested, repaired (only if necessary), and retested again to ensure the highest quality control. Each unit must pass a complete battery of test before it can be titled a "Yamaha Factory Refurbished" product.

Most units are Cosmetically in Mint Condition (graded a 9 or higher on a scale of 1-10). Very minor signs of wear (light surface scuffs or minor scratches) may be present, although most units show little or no signs of any usage. We DO NOT sell products that are cosmetically damaged (cracked displays, broken knobs, heavy scratches, or physically abused) unless noted in the description. Unfortunately, we can’t provide actual photos of each unit or pick the best one for anyone, as they are all randomly chosen from our factory sealed boxes.

Great with Yamaha R-S700 stereo amp

5 YAMAHA NS-555 3-Way Bass Reflex Floorstanding Speaker Black Each
Reviewer: from Sonora CA
Tried a few floor standers to replace a pair of 90s JBLs. Not impressed until I tried these. Setup: Yamaha R-S700 receiver from Marantz CD and Oppo BDP-95 with Polk PSW-505 sub for 2.1 music (CD, SACD, DVD-A). They fill a 28 x 18' room very well.

Good clean mids, well balanced highs (not sibilant like Titanium JBL tweeters), good bass, but I use the sub anyway. Placement is important - keep away from back wall for bass since they are rear ported. When placed well, the sound stage is very good. You can pick out individual guitar parts and background parts since they are so 'clean'. They really shine with good recordings, but poor recordings can be difficult to enjoy.

I read that the 777s were not as strong in the mid, but I personally have not compared them.

Only issue was the shipping boxes... two different sizes, and neither was packed very well. Speakers came through unblemished. Some assembly required: Adding feet took quite a bit of effort to secure screws.
