Looking for great-performing bookshelf speakers? Then take a closer look at these Yamaha NS-6490 8 In. 140 Watt Max 3-Way Bookshelf Stereo Speakers! This speaker pair is ideal for any home theater or stereo application. Grilles are included.

    Q: do these come with a 3.5 mm plug and are they compatable with pcs

    A: I don't own these but my assumption would be no... instead you would need a receiver or a DAC/Amp. You would connect the PC to the DAC/Amp or Receiver via USB. Then you would connect the DAC/Amp to the speakers using regular speaker wire. This would be a better set up than any computer speakers available.

    Q: What is the best wall mount bracket for these speakers?

    A: To be honest Best Buy does not sell a GOOD option for brackets for these speakers. I bought the largest brackets they sell, the Sanus WMS2, and they BARELY work. So, while you could use the WMS2, I would recommend looking elsewhere. The pictures do not do justice how big these bookshelf speakers are.

    Q: I bought a Yamaha CD-C600 5-Disc player. I take it, that I need a receiver hooked up to the CD player to hear anything. But, do I also need speakers? You can tell I am out of my element, but I am trying to learn.

    A: jmac, yes you will need some sort of amplifier to power the speakers. You will likely also need some kind of pre-amplifier to control volume and select input (CD Player). If you buy a receiver, they have amplifier and pre-amplifier in one unit, so this is often the most cost effective way to go. If you do not plan on upgrading to surround sound in the future, I recommend purchasing a stereo receiver like the Yamaha R-S202BL. Surround sound receivers are a bit more complex to configure so if you aren't going to get surround sound you might want to keep it simple. Hope this helps.

    Q: Do these come with wires?

    A: No, these speakers do not come with the wires.

    Q: Will the speakers work on a six year old Visio television?

    A: The speakers are not powered so you would need an amplifier.

    Q: Will these speaker work on a 8 ohm system?

    A: Yes, they will work fine on most any home stereo system with standard 8 ohm load requirements.

    Q: are these speakers plug in or bare wire connectors

    A: I used gold plated connectors with high gauge speaker wire. You can also use bare wire connectors
