Our take on the Yamaha NS-6390
Don't let the compact cabinet or the affordable price tag fool you the NS-6390 delivers big sound that doesn't skimp on Yamaha's trademark musical precision. It features a 3-way design for impressive power handling, and solid, accurate performance from top to bottom. The NS-6390's video-shielded, acoustic suspension enclosure incorporates a 3/4" fluid-cooled dome tweeter, a 4" midrange, and an 8" woofer. You'll love the clean, punchy sound! Both the midrange and bass drivers feature inverted dust covers for added durability.

Power Handling Note
Three-Way Acoustic Suspension Speaker: Yamaha's NS-6390 utilizes an 8" Hi-Polymer coated woofer and 4" aluminum-color midrange, both with inverted dust caps, and a 3/4" Ferro-fluid cooled balanced-dome tweeter.
Magnetic Shielding: Each speaker is magnetically shielded, so they can be placed near a TV or video monitor without degrading the picture via stray magnetic fields.
Spring-Type Terminals: The spring clips will accept pin connectors and bare wire.
New Grille Design: The new grille design and satin grille cloth provide an attractive and acoustically transparent protective cover for the drivers.
Power Handling: The nominal (average) power input rating is 70 watts, and the maximum RMS power handling is 140 watts. Yamaha does not specify a peak power rating.
