Yamaha NS-B901 Speaker Specification

The Yamaha NS-B901 is a high-performance bookshelf speaker designed to deliver superior audio quality through advanced acoustic engineering and premium materials. It features a 2-way bass-reflex design, equipped with a 13 cm (5”) aluminum cone woofer and a 3 cm (1”) aluminum dome tweeter, which together ensure a wide frequency response and precise sound reproduction. The speaker's cabinet is crafted from non-parallel surfaces to minimize unwanted vibrations and resonances, enhancing the clarity and detail of the audio output. The NS-B901 employs Yamaha’s signature A-PMD (Advanced Polymer-injected Mica Diaphragm) technology in its woofer, which contributes to its lightweight yet rigid construction, allowing for rapid and accurate sound response.

The tweeter incorporates Yamaha’s DC-Diaphragm technology, integrating the diaphragm and voice coil to extend high-frequency performance and improve transient response. This results in a seamless and dynamic sound experience, making the NS-B901 ideal for both music and home theater applications. The crossover network is meticulously designed to ensure smooth transition between frequencies, providing balanced and natural sound across the entire audio spectrum. The speaker's elegant design is characterized by a luxurious finish, available in gloss black or piano white, which complements any high-end audio setup. With a nominal impedance of 6 ohms and a sensitivity of 87 dB, the NS-B901 is suitable for various amplifiers, offering flexibility in system integration. Overall, the Yamaha NS-B901 is engineered to provide audiophiles with a rich, immersive sound experience through precision craftsmanship and innovative acoustic technologies.

Yamaha NS-B901 Speaker F.A.Q.

How do I properly set up the Yamaha NS-B901 speakers for optimal sound quality?

To set up the Yamaha NS-B901 speakers for optimal sound quality, position them at ear level, ideally forming an equilateral triangle with your listening position. Ensure they are placed at least 30cm away from the wall to allow bass reflex ports to function effectively. Angle them slightly towards the listening position for better stereo imaging.

What should I do if there is no sound coming from the Yamaha NS-B901 speakers?

If there is no sound from the speakers, check the speaker cables for secure connections to the amplifier. Ensure the amplifier is powered on and set to the correct input source. Verify that the volume is turned up and not muted. Test the speakers with another source or amplifier to rule out a problem with the original setup.

How can I clean and maintain the Yamaha NS-B901 speakers?

To clean the Yamaha NS-B901 speakers, gently dust the cabinet with a soft, dry cloth. Avoid using chemical solvents or abrasive materials. For the grille, use a vacuum with a brush attachment or a lint roller. Ensure the speakers are unplugged and powered off before cleaning.

Can the Yamaha NS-B901 be used with any amplifier?

The Yamaha NS-B901 speakers can be used with most amplifiers, but it's important to ensure the amplifier's power output matches the speaker's power handling capacity. The NS-B901 has a nominal impedance of 6 ohms, so check that the amplifier can handle this load to avoid damage.

What is the best way to position the Yamaha NS-B901 speakers in a home theater setup?

In a home theater setup, position the Yamaha NS-B901 speakers as your front left and right channels. They should be equidistant from the TV and angled towards the listening area. Ensure they are at the same height as the center speaker to create a cohesive soundstage.

Why is there distortion at high volumes with the Yamaha NS-B901?

Distortion at high volumes may occur if the amplifier is overdriven, or the speakers are receiving more power than they can handle. Ensure your amplifier's power output is within the NS-B901's recommended range and avoid setting the volume to maximum levels. Check for any damage to the speaker cones or wiring.

How do I connect the Yamaha NS-B901 speakers to a subwoofer?

To connect the Yamaha NS-B901 speakers to a subwoofer, use the speaker-level inputs or outputs on the subwoofer if available. Connect the amplifier's output to the subwoofer's input, then connect the subwoofer's output to the NS-B901 speakers. Adjust the crossover settings on the subwoofer to blend seamlessly with the speakers.

What is the recommended break-in period for the Yamaha NS-B901 speakers?

Yamaha NS-B901 speakers generally benefit from a break-in period of about 50-100 hours of playback. During this time, play a variety of music at moderate volume levels to allow the speaker components to loosen up and deliver optimal performance.

How can I enhance the bass response of the Yamaha NS-B901 speakers?

To enhance bass response, try positioning the speakers closer to the walls or corners of the room. Use quality speaker cables, and ensure the amplifier provides adequate power. If more bass is desired, consider adding a dedicated subwoofer to your setup.

Are there any specific room acoustics considerations for the Yamaha NS-B901?

For the Yamaha NS-B901, room acoustics can significantly impact sound quality. Use rugs or carpets to minimize reflections, and consider adding acoustic panels for better sound absorption. Avoid placing the speakers in corners or against bare walls to prevent excessive bass buildup.
